Version 9.01 (2011-02-07)

This is the second release in the stable 9.x series.

Highlights in this release include:

A new, robust CFF parser implemented in C (replacing the previous Poscript one),

tiffscaled device - this renders internally as tiffgray, but then downsamples by an integer scale factor (specified by -dDownScaleFactor=n) and error diffuses to 1bpp output. The tiffscaled device also implements limited minimum feature size functionality; by setting -dMinFeatureSize to 1, 2 or 3, the device output is guaranteed to generate minimum dot sizes as multiples of the final resolution, useful for devices that offer finer position control than dot size control.

Add DSC compatible output in ps2write.

Windows makefiles now support 64 bit builds on 64 bit systems.

A number of performance, memory use, and stability improvements with the new features introduced in 9.00, plus the usual bug fixes.

We have also dropped support for Watcom and Borland development environments. These had not been maintained for some time, and were suffering "bit rot".

Merge r12117 from the "halftone" branch into trunk, the original commit
comment says:

Fix bug in bit devices rgb mapping procedure; in the ncomp == 1 case it
was only setting the first component. This was causing indeterminisms in
calling code, which has been giving vastly different timings in Norberts
tests.

This has apparently been here since revision 3318.

Change Windows makefiles extensively for 64-bit issues:
1. Command line nmake works now for 32-bit build on 64-bit OS
2. 64-bit builds use different directories for objects to allow 32 and
   64 bit builds to be alternated without confusion. 64-bit objects have
   '64' suffix to the 32-bit objects which remain in the same places
3. 64-bit binaries are now named uniquely, e.g. gsdll64.dll and gswin64.exe
   Binaries coexist in 'bin' directory since names are unique.
4. 'Style' changes to the makefiles to remove the '32' suffix from files
   that are not 32-bit specific -- hopefully will prevent future confusion.

Tested with VS 2005 and VS 2008 as well as with GhostPDL.sln (to make sure
the pcl, xps, and language_switch builds don't break.

Fix (ps2write) : Enable ps2write on PCL

Bug #691881 "ps2write broken with GhostPCL"

ps2write formerly required 4 'resource' PostScript files stored on disk in order to
write a PostScript header to the output file. These files have now been converted into
'C' header files and included in the source in earlier revisions.

This commit removes the last barrier to ps2write working with PCL (and other
non-PostScript languages) by removing a disk-based check for opdfread.ps.

No differences expected.

cluster build and shouldn't conflict with anyone else.

2011-02-02T14:12:15.676565Z Chris Liddell

A set of changes to make it easier to use the UFST with Ghostscript
and to get us closer to having the option of the UFST handling font
types other than the Microtype fonts.

The UFST build, using the default COMPILE_INITS=1  will now include
the Microtype FCO files in the rom file system along with the other
initialisation files (it does not currently strip out the normal
Postscript fonts in Resource/Fonts), and setup default values for
the various paramters required to have Ghostscript use the
Microtype fonts (these can still be overridden on the command
line). For the build with COMPILE_INITS=0, the default paths
will use the path to the UFST you specify for configure, or
nmake on Windows.


Included in this revision are changes to prevent the UFST version
5.x (or less) from trying to handle non-Microtype fonts, and allow
it to safely fall back to the Freetype (or a.n.other FAPI plugin).
UFST 6.2 or better will try to handle all fonts types, but this is
not yet reliable.

Currently, this code only replaces the UFST memory management on
UFST 6.2 and above (this is purely because I haven't time to test
this capability on UFST 5 yet).

A further change will be committed shortly to the UFST 5 sources
to force the UFST to use the Ghostscript stream IO instead of the
standard lib file IO on the Windows builds (this has been in place
for the Unix/Linux UFST builds for some time).

Fix ps2write : Don't depend on the PS file system for resources.

ps2write needs up to 4 resource files which are normally stored in the PostScript ROM
file system. However on PCL and other languages these resources are (obviously) not
present, so the output is incomplete.

Move the relevant files from PostScript into 'C' as header files. Remove the files from
the PostScript file system to save ROM file system space. Put the removed files into
the gs/lib folder for safe-keeping. Add the .h files as dependencies for gdevpdfu.c in
the build system so that changes to these files cause a rebuild.

No differences expected.

Fix (pdfwrite) : Always write a ToUnicode CMap for TrueType fonts

Bug #691907 "PDFs with TrueType fonts from Windows PostScript files not searchable"

Patch from SaGS.

When choosing whether to embed a ToUnicode CMap, always embed if the font type is 
TrueType. This is because TT fonts are always embedded as symbolic, and we now no longer
add Encodings to Symbolic TT fonts (violates spec), which results in PDF files where the
text is unsearchable and cannot be successfully copy/pasted in the absence of a
ToUnicode CMap.

It is possible that the ToUnicode CMap is incorrectly generated, but this is no worse
than having no CMap at all.

No expected differences since ToUnicode CMaps are not used in rendering.

Add new 'Profile' configuration to Visual Studio targets. This builds
objects/binaries with debugging symbols enabled, but otherwise full
optimisation.

The changes are entirely within the VS files, except for a few small tweaks
to the MSVC makefile. These changes should mean that it is possible to use
the makefiles in a way that doesn't rely on recursive make calls (even though
we leave the 'debug' targets in for now that do use that).

No cluster differences expected or shown in testing.

Fix (pdfwrite) : permit symbolic fonts in PDF/A output

Bug #691877 "Invalid text when converting to PDF/A"

TrueType fonts were being emitted as non-symbolic when PDF/A output was selected. This
was causing the text to be incorrect, because the fonts actually are symbolic and 
Acrobat was unable to apply the correct decoding.

This will result in more text being unsearchable/copyable but the rendering result is 
correct, which is more important.

No differences expected, PDF/A output not tested on the cluster.

While searching for performance on an ARM based dev board, I developed 2
new versions of the skip_white_pixels macro. The first uses native int sized
checking, and should be faster on long run matching. I have as yet been unable
to find any files that show this expected speedup.

The second should be faster on architectures (such as ARM) where the tradeoff
in the test is different (and where pointer arithmetic is cheaper than array
indexing).

Both versions are disabled by default until the case for their existence has
been proven, but are committed here to avoid bitrot.

No cluster differences expected, as the default code does not change.

More changes for CUPS, mostly to the build system.

We now build the CUPS device unconditionally on Windows, using the recently added local
partial copy of the CUPS library sources. This change also builds CUPS on Linux either
using the system shared libraries (if available) or using the same partial copy of the 
library sources, if *specifically* directed to use this.

On Windows CUPS is now always built and installed. On Unix systems the behavious is as
follows:

./configure cups not installed  - no cups device
./configure cups is installed   - cups device linked to system cups shared libraries.
./configure --disable-cups      - no cups device, regardless of cups libs installed
                                  on system
./configure --with-local-cups   - cups device with the partial cups code, regardless of
                                  cups libs installed on system
./configure --with-local-cups --disable-cups results in no cups device.

No differences expected as the cluster should still build and run with the system
CUPS libraries just as it always has.

More changes to the CUPS sources so they will compile on various systems:

language.c - if __APPLE__ is true, includes code which uses what I think is Carbon
             Framework calls and structures, but does not #include any of the .h files.
             Modified to #undef __APPLE__ to avoid this.

ppd.c  -  Same problem as for MSVC, the include file string.h seems to prevent the C
          string.h being included, and so leaves strchr undefined. Now unconditionally
          provide a prototype for strchr.

localize.c - Another problem with string.h. This doesn't exist on the MSVC build, but
             unconditionally providing a prototype fro strcmp doesn't cause an error.

The code now builds on MSVC, Linux and Mac. Lots of warnings, but I don't propose to
try and deal with those as they would require extensive alterations to the CUPS
sources.

No differences expected as this code is not yet in use.

Optimisations to mem_mapped8_copy_mono. Driven initially by a desire to
speed up 100pagemono.pxl on ARM devices, but useful on all architectures.
This work may end up being subsumed by the run_rop work, but is a worthwhile
stepping stone.

On x86 this speeds 100pagemono.pxl in greyscale 600dpi from 4.2 seconds to
3.6seconds. On ARM it shows a definite improvement too, but I don't have
figures to hand.

Clusterpush shows no changes.

2011-01-27T14:33:46.308935Z Ken Sharp

Update the CUPS sources so that they can be compiled under Windows.

1) Remove config.h which was a Linux configure result, replace with configwin.h (from
the CUPS distribution for Windows) and configlinux.h which is config,h renamed. We
will copy and use the correct version at make time.

2) cups/debug.c guard the use of pthread_mutex so that we don't try to use it if
HAVE_PTHREAD_H is not defined, as the variable will not be declared. Guard use of 
cups_debug_filter and cups_filter with a #ifndef WIN32 as these variables are not 
defined in a Windows build. Replace gettimeofday with a Windows equivalent when 
building on Windows as this function is not available.

3) ppd.c Add a definition of strchr when building for Windows. The use of an include
file called string.h confuses MSVC and it does not include the C string.h which leaves 
strchr undefined.

4) string.h When defining equivalents to strcasecmp and strncasecmp, also define the
HAVE_* variables so that inclusion order doesn't lead to these being undefined when
we have declared equivalents.

5) image-bmp.c Guard the declaration of the BI_* constants with a #ifndef WIN32 as 
these are Windows constants and already defined on a Windows build.

6) image-colorspace.c Define cbrt() in terms of pow() when WIN32 is set as the MSVC
compiler does not define a cube root function.

7) image-tiff.c Guard inclusion of unistd.h when HAVE_LIBTIFF is true as this include
file does not ship with MSVC on Windows.


These have been supplied to the CUPS development group, and at least some of the
problems are likely resolved in a newer version of CUPS. 

No differences expected.

We want to be able to use planar buffers in a line interleaved format.
Unfortunately, at the moment the planar device is hardcoded to use
contiguous buffers. Fortunately this appears to be a 1 line fix; rather than
calculting raster from the width, we instead calculate it as the difference
between line pointers.

This does assume that we can always safely read line_ptrs[1], even if we only
have 1 line in the band. (The value is unimportant in this case, but we must
be able to read it without crashing.)

Reorganise and correct the names of the devices specified in

actually work.

Finally, make the "make debug" compiler options originate from
configure, instead of being hard coded into the Makefile. A first

Revision 12038 revealed a bug in the transparency code; an operation with
a blend mode of 'Normal' and a solid alpha would be allowed to use the
fast stroking code, even though it had transparency in due to being a pattern.

Here we fix the code to check for transparency. As noted on bug 691900 this
test treats all type 2 patterns as being transparent, so could be improved.

The cluster differences this gives have been checked and correct the
regressions of revision 12038.


[base/gdevp14.c base/gstrans.c]

2011-01-19T18:00:59.394482Z Robin Watts

Bug 691897 shows a PDF that is much slower when transparency is enabled than
when it is not. The time is primarily spent in the stroke filling code due
to the fact that when transparency is enabled strokes need to be rendered
all at once, rather than segment by segment. This causes the scan conversion
code to have to work much harder.

In fact, the code uses solid alpha and "compatible" blend mode for most
strokes, so we would be perfectly safe to use the normal mechanism. The
code attempts to recognise this case already, but was only spotting "Normal"
blend mode and not it's synonym "Compatible". We now roll the two together.

SunStudio 12 has changed the default optimization level option for cc to
be -O3 (previously was -02), which results in Ghostscript crashing.

Changes to the Unix configure based builds to tidy up specifying
subsets of output devices.

Some devices were always being included regardless of the options
given to configure, resolved by tidying up the macro expansions
in Makefile.in done by the configure script.

Also the page device and clist device are effectively required by
all configurations, so those are now included in the core build.

Finally, the contrib/gomni.c driver relied on two functions in
base/gdevbmpc.c which is an optional driver, so configuring
the Omni driver to be built it, and bmp16 not would result
in undefined symbols. contrib/gomni.c now has its own
equivalents of those functions.

The bbox device remains as the ultimate "fallback" device.

Hopefully a fix for indeterminism introduced in rev 12005.  The source of this was that the cups and psdcmyk device are now using the older slower color image rendering function due to the fact that they have non-standard color mapping procedures.  Missing parenthesis were introduced when the ICC branch was merged into the trunk which was the source of the issue.  This was causing a check for color range mask testing even when the image was not a type 4.

Added the source code of the CUPS libraries to the Ghostscript source
package

Like with zlib, libpng, libjpeg, ... it is now possible to
build the complete Ghostscript (including the CUPS Raster output
device) on systems where there is no CUPS library available.

Note that currently only the CUPS library source code is added, the
results of the ./configure run in the Makedefs and config.h files, and
the Makefiles are stripped to only build the libraries and nothing
else. The CUPS ./configure command line which was used to obtain
makedefs and config.h was

./configure --enable-static --without-shared --disable-dbus --without-php \
--disable-slp --disable-gssapi --disable-ldap --disable-ssl \
--disable-cdsassl --disable-gnutls --disable-openssl --disable-pam \
--disable-dnssd --disable-launchd

This way the built CUPS libraries do not need any system services or
hardware interfaces of Linux. In addition to standard libraries they
use only libz, libpng, libjpeg, and libtiff. These libraries
Ghostscript needs anyway and copies of their source code also ship
with Ghostscript.

What is still missing is the integration into the build system of
Ghostscript and also the operating-system-independent base/cups.mak
file (like base/png.mak etc.).

No changes expected in the built Ghostscript as the code is not yet
integrated in the build system.

Fix so that we do not do the ICC optimized flow for color images when our target device does not have standard color mapping procedures.  This occurs for example, in the case for the CUPs device where the color mapping procedures map CMYK, RGB and Gray to the current CUPs device color space.   For standard gray, RGB and CMYK devices these procedures are avoided as the CMM performs all the required mappings.  This commit will show differences in the files for the cups device as well as the psdcmyk device, which also should be using the non-optimized flow due to the use of CMYK + spot colorants, which will not be managed correctly by the CMM in general.  The differences int the psdcmyk files that do not have extra spot colorants are tiny.  This should fix bug 691760.

Use the "x11" output device as default output device for an X-enabled Ghostscript, as "x11alpha" is too buggy

The simple call "gs <file>" is a common call to check a PostScript
file when debugging printing problems. Unfortunately, this call uses
the "x11alpha" output device which has a lot of bugs, especially on
complex input files. This makes easily a wrong impression of the input
file then. Having a somewhat inferior screen output quality (no
anti-aliasing) is no problem as the mentioned Ghostscript call is only
used for debugging purposes.

ps2write DSC enhancement. Belt and braces approach when emitting a serialised array/proc

This code should break an (already serialised) array or procedure emission if the total
length of the data to write exceeds 255 bytes. The data will be broken at name, array,
string or procedure tokens (ie '/', '[', '(', '<') or a space character. If none of
these occurs in the preceding 255 bytes then we emit a line break anyway and carry on.

I do not have any test cases which exercise this code path with a data size > 255
bytes, so I'm not certain that it works as expected.

No differences expected as the regression test doesn't exercise ps2write.

Fix so that the presence of source black and white are properly detected with the ICC color management changes.  This detection is useful for the optimization of certain ROPs.  Previously black and white were detected from looking at the device color.  This was a problem since the device black color is usually not pure for a CMYK printer with the ICC changes.  This fix updates the detection function so that it looks at the source color and maps it to the default RGB color space where black and white are well defined.

Fix (pdfwrite) : Write ToUnicode CMap files which Acrobat likes

Bug #691862 (and also bug #691849) "Unable to copy text from the converted PDF"

It seems the Adobe documentation lies (or more generously is inconsistent). The
CMap tech note (5014) says that entries are not zero padded, so values less
than 256 are emitted as single bytes, values 256->65535 are two bytes etc.
However the ToUnicode CMap tech note (5411) says:

"Because a “ToUnicode” mapping file is used to covert from CIDs (which begin at
decimal 0, which is expressed as 0x0000 in hexadecimal notation) to Unicode
code points, the following “codespacerange” definition, without exception,
shall always be used: 1 begincodespacerange  <0000> <FFFF>endcodespacerange"

(This is somewhat restrictive, since CIDs can exceed 2 bytes, even though
UTF-16 can't, I could forsee a need to map high CIDs to lower UTF-16 values)

Finally, the PDF Reference (1.7) says:

"The CMap file must contain begincodespacerange and endcodespacerangeoperators
that are consistent with the encoding that the font uses. In particular, for a
simple font, the codespace must be one byte long."

So the PDF Reference conflicts with the tech note which it references!

In fact none of the above seems to be quite what Acrobat actually does. 

It seems that Acrobat does not care what size (in bytes) the codespacerange is,
no matter what kind of font is present. However it *does* care what size the
bfrange entries are. For simple fonts the bfrange entries must be single bytes,
for CIDFonts the bfrange entries must be two bytes. Deviation in either case
leads to files which Acrobat cannot process and either causes errors or
incorrect text when copying and pasting.

Changed the ToUnicode emission (mostly restoring revision 11170 which was removed in
revision 11795 because of bug #691849) so that we emit single byte bfrange and 
codespacerange arguments for simple (non-CID) fonts, and emit double byte, padded with
00 arguments to bfrange and codespacerange for CID fonts.

No differences expected as this only affects text search/copy in Acrobat.

The optimization in gdevdgbr to detect a device with a "plain" cmyk 1
bit to rgb mapping was broken because the procedure
cmyk_1bit_map_color_rgb() is obsolete.  The hack here is to detect
output formats compatible with gx_get_bits_copy_cmyk_1bit() which is
significantly faster since it does not have to call the device color
decode procedure.  The device API should have a member that indicates
the most frequently encountered pixel organizations.

Fix ps2write : Attach Encoding for symbolic TrueType fonts

The recent change to not attach Encodings to Sy,bolic TrueType fonts, as per the PDF
spec, meant that ps2write also wrote symbolic TT fonts without a /Encoding. This is not
ideal, because opdfread.ps then attaches a default StandardEncoding to the font. This
simply will not work correctly.

After some experimentation with extracting (in PostScript) the POST table from the TT
font, sense prevailed. This patch modifies the condition so that if we are producing
output for ps2write we continue to attach a /Encoding. (in this case it doesn't
matter whether we are producing DSC output, we always want the Encoding)

Bug #691849 "pdfwriter regression: pdf text element is broken"

revision 11170 modified CMap emission so that bfchar/bfrange entries less than 256 were
emitted as a single byte, as specified in the CMAp specification. However ToUnicode
CMaps don't follow the normal specification (I suspect this is a bug which has been

Initial commit of code for creating halftone screens.  This code needs additional debugging, especially in the case of edge parameters.  It will currently create threshold arrays based upon desired lpi, angle, quantization levels, and device resolution.  The method is restricted to angles that are the arctangent of rational numbers. Every attempt is made to achieve the requested lpi by using the rational angle that achieves an lpi over the requested value.  Since there is a trade off between lpi and quantization levels, the requested quantization levels are obtained through dithering of the dot cells within the supercell.  Essentially, the dots within the supercell do not all take on the same values and can grow at different rates in a visually pleasing manner.  There is still a bit of work to do still on this dithering as well as controlling the rate of growth for the dots.

More enhancement work for type 3 fonts with PCL

Previously we set the horizontal advance argument to the d1 (setcachedevice) operator to
0, and set the Widths entry to 0, for all type 3 bitmap fonts created by rendering the
original font.

This was required to prevent regression errors with the test suite when we altered the
type 3 font accumulation so that it made more effort to preserve the input character
code, in an attempt to improve searching.

Revision 11969 fixes a problem with cached characters which was leading to the /Widths
array containing garbage values. With that revision we can now properly set the 'd1'
horizontal advance, and also set the /Widths array correctly.

Fix ps2write/pdfwrite : Up date the show enumerator with the cached character width

When capturing a character bitmap on the first time it is rendered, pdfwrite and
ps2write get the width of the glyph in the cache device. This is then used to update
values in the show enumerator, and these values are used as the Widths entry for the
glyph.

When imaging an already cached character, however, the enumerator values are not updated
which can lead to garbage (uninitialised data) being written as values in the /Widths
array. This patch takes the value from the cached character 'wxy' and updates the show
enumerator 'wxy' with it. This is then used as the value for the /Widths array.

Bug #691839 "Invalid EPS conversion with -dEPSCrop"

Rectangular fills (and only the special case of rectangles) were being clamped to the
width/height of the device when emitted. This can cause problems when a matrix is in
force which reduces the actual co-ordinates, in this case a Pattern with a 0.25 scaling.

The clamping caused co-ordinates to be reduced, and part of the fill went missing.

The comment indicated this was to 'work-around' the limit in Acrobat of 32k on user
co-ordinates, but this is too sever a clamp to apply, also the general case path code
does not apply this limit. Altered to make the limit the 32k enforced by Acrobat.

pdfwrite enhancement : more DSC related activity

Defer the output of the header and the opdfread.ps 'prcoset' until the output file is
closed. This allows us to count the pages and emit the %%Pages: comment in the header
instead of at the end of the file.

Fix the PageBoundingBox comment to have two % characters instead of one.

Check for a new flag 'DSC_OPDFREAD' at the start of opdfread.ps (and write its
definition as part of the header emission in ps2write). If present this prevents the
SetupPageView routine from using setmatrix to reset the CTM to the one saved during
document setup. Because the DSC-compliant output puts save/restore around each page
we don't need to reset the matrix, and the reset prevents the output from working
properly with psnup. If the flag is not present, it is treated as false.

The output now works with GSView, psselect and psnup. The only remaining work is to
track the usage of ProcessDSC and see if we can reuse any of the comments parsed out
of the input.

pdfwrite enhancement : More work towards DSC compliance

This is a resubmission of revision 11941, with some additional changes so that it
doesn't crash with pdfwrite on Linux systems. 

We now pass around the 'type' of an object much more when writing. This is so that
we can emit "%%BeginResource/%%EndResource" comment pairs around the resources we write.
It is also required so that we *don't* write these comments around pages.

The code now emits %%BeginProlog, then writes the opdfread.ps procedure. It then writes
all the various resources used in the document, each with a reasonable DSC comment. Then
it writes %%EndProlog. After this come the page descriptions, each is written with a
%%Page: comment and a %%PageTrailer. Finally we write the %%Trailer, %%Pages
comment (NB we write %%Pages: (atend) in the header comments as we don't know how many
pages there will be until the end) and %%EOF.

The resources are mostly defined as being of type 'file', as most of them are not normal
PostScript resources. The DSC specification says under the %%BeginResource definition 
(file note on p72) "The enclosed segment is a fragment of PostScript language code or
some other item that does not fall within the other resource categories" and so this
seems the best type to use for our purposes.

The output is now minimally DSC compliant, though there are a few other comments I'd
like to add if possible. Given the way the file is created we are always going to have a
large prolog, and that will need to be copied to all the pages if they are split
individually, in order to make sure that all the required resources are present.

Technically we could follow the resource chain and write %%IncludeResource comments,
at the page level at least, but this is probably more effort than it is realistically
worth.

Still need to add some more DSC comment types, and run some extensive testing.

No differences expected currently. Minimal testing with GSView suggests that the output
so far is DSC-compliant as-is.

A change to how we get the advance width of the glyph from Freetype.

Previously, we used the data in the glyph metrics structure, which
are scaled, and the undid the scaling. This is correct method for
everything except the horizontal and vertical advance distances.

We now get the two advance distances from the glyph structure,
and tell Freetype not to scale them, this avoids the rounding
errors that occur due to Freetype's fixed point number
format. It also saves the (less significant) error when we
previously unscaled the value, and saves a couple of
fairly large double precision calculations.

This does cause a number of changes in the regression suite,
the vast majority are pixel or so differences in glyph
positions. A very few are improvements.

Fix (pdfwrite) : Hashing /Subrs didn't check all subrs.

Bug #691815 "ps2pdf fails on attached ps file"

The new code for hashing /Subrs, to improve font checking performance, stopped comparing
/Subrs between two fonts as soon as either font had an error getting a specific /Subr. 

However it transpires that some fonts can have a null object for a /Subr (used to skip
Subrs that do nothing), and this returns a typecheck error. This led to two fonts which
differed only in the fact that one has (and uses) more Subrs than the other being 
perceived as identical. This could lead to pdfwrite using the wrong font when 
converting type 1 into CFF fonts and cause errors.

The code now continues checking remainign /Subrs if a typecheck error occurs, and as an
additional measure also checks the number of /Subrs in each font before deciding if
they are compatible.

Acrobat 4 & 8 have a peculiar bug, if a type 3 font (may affect other font types, but
it seems unlikely) has a WinAnsiEncoding, and no /Differences, then text set in that
font is not displayed by these versions of Acrobat. This may be limited to glyphs
which consist of a bitmap only.

Forcing the emission of a /Differences array for each glyph used results in these
versions of Acrobat displaying correctly (even though the 'differences' are in fact the
standard Encodings).

other PDF consumer seems to have a problem with these files.

Due to "lazy evaluation" of softmask groups, the graphics state can change between
the creation of the softmask group form, and when it is executed.

We'll now save the gstate and (most of) the ExtGState when the softmask group is
defined, and then set both before evaluting the object. A few ExtGState entries
are not easily set directly, so those are missing.

This partially fixes Bug 691157, and fixes Bugs 690351, 691348 and 690535. It
also resolves the remaining issue with 690535.

Fix (pdfwrite) : Type 3 font capture and charpath operations

Bug #691033 "Regression: 14-01.PS fails with pdfwrite"

The first time a type 3 glyphis  encountered we start a charproc accumulatiopn and
exit to run the BuildChar/BuildGlyph. On return to the text processing, if the 
operation was a charpath, this would take precedence over closing the accumulator which
would lead to significant later problems.

Modified the code path to allow for the charproc accumulation to finish and if this is 
a charpath operation to rerun the operation using the newly captured glyph program.

Note this can only occur if the first operation on a given glyph in a type 3 font is 
for a charpath.

Fix (pdfwrite) : pointers not marked for garbage collection

Bug #691779 "SegFault with pdfwrite and more than one cid font"

pdfwrite does lazy creation of Identity ToUnicode CMaps for inclusion in output PDF
files (2 CMaps, one for horizontal and one for vertical writing). These pointers were
not marked for the garabge collector, but were stored directly in the pdf device
structure.

The CMaps were assigned to a pdfont resource type, where the pointer to the CMap *was*
marked for the garbage collector. This meant that if the pdfont resource was moved as
a result of garbage collection, the CMap could be moved as well. This left a dangling
pointer in the device structure. 

If another font resource required an identity CMap then the now garbage pointer from
the device structure would be assigned. If the new font resource was moved as a result
of garbage collection, then the attempt to relocate the CMap would fail and cause a
crash.

Fixed by marking the pointers in the device structure for the garbage collector.

No differences expected.

Fix for bug 691785.

The bitmap mask clip device has a long standing bug when attempting to clip
a bitmap through a 1bpp bitmap (gxclipm.c, clip_runs_enumerate, line 283ish).

The code detects runs of 'on' pixels in the mask. It then keeps the last run
it found in a 1 place buffer (called 'previous'). This therefore represents
the previous run found. Whenever we find a new run, we check to see if we can
add it to the previous run to try to form a larger (vertical) rectangle. If
we can't, we should write the previous rectangle out and remember the current
one.

Unfortunately the code was writing the current rectangle out, rather than the
previous one. This has the effect of losing the first run on most lines out.

Fix so that we handle the \B command properly when we have transparency.  The stroke should be drawn in a knock-out fashion rather than blended with the fill.  This was achieved by adding in the push of a knockout transparency group for the stroke operation.  The opacity for that group had to be 1 rather than what ever the current graphic state was (otherwise you end up with the opacity applied twice).  That change revealed an issue in the clist when a transparency group is pushed where the opacity for the pdf14 clist device was being altered without having the information passed into the clist.  Fixing that required a few changes to make sure that the blend parameter changes for the transparency group end up written in the same bands as the group push rather than all bands like the normal blend parameter change compositor action does.  A few changes were needed in the clist compositor writing code to make sure that this special blend parameter change did not push a new cropping item on the cropping stack.  This commit results in a lot of progressions.  However, the cluster push revealed a couple files fts_06_0608.pdf.pdf.ppmraw for example, which may have an issue.  These are being checked and if found to be an issue a new bug report will be filed.

pdfwrite enhancement : attempt to make PCL bitmap fonts into searchable type 3

In general pdfwrite only resorts to making a bitmap from a font when it cannot handle
the original font type, which is rare for PostScript, PDF and XPS. However all PCL
bitmap fonts are handled this way.

When this happens, the bitmap is stored into a general type 3 font, a 'bucket' where all
such glyphs are stored. When this font is full, a new one is started and so on. The text
stored in the PDF page stream references the correct type 3 font, but usually the
character code will be unrelated to the original character code.

For PCL bitmap fonts pdfwrite actually starts by creating a type 3 font to hold the 
PCL bitmaps, but doesn't use it. This patch tries to store the bitmaps in the type
3 font where possible, using the character code from the original PCL document. 
Although this will not create searchable text in the general case, it does seem that
there are a good number of PCL documents which do use an ASCII encoding and so will
produce a searchable PDF file.

There are several caveats:

1) This only works at all with cached glyphs. Glyphs which are too big to fit in the
cache are instead rendered as images, not text at all. The cache has a compiled limit
of 2500 for the height of the bitmap, but this needs to take the resolution which is
being used for rendering into account. The default resolution for pdfwrite is 720 dpi
which means that bitmaps larger than ~125 rows will not be cached. (see below for more)

2) Certain kinds of text operations can't be handled at all; any case where a character
code does, or may, exceed 256 cannot be handled. These cases are handled as before by
placing in a special font with a unique character code and called from there.

3) If the font matrix is not the identity we cannot handle the glyphs, as the bitmaps
stored in the cache already include any transformations present in the Fontmatrix and
we can't undo those transformations to the bitmap. In practice this means that if the
canvas orientation (not the media) is not portrait, then this will cause the text to
be non-searchable.

4) The Acrobat searching algorithm does not work very well with this kind of text. In
our case each glyph is individually positioned on the page rather than being written
as a continuous stream of characters. Acrobat seems unable to find more than about
three glyphs in succession this way.


There is no further scope for improvement in pdfwrite as far as I can see. The only 
way to handle this better would be to make changes in the PCL interpreter so that the
bitmap PCL font is created as an actual font (probably a TrueType). This would mean that
the text would be stored in the PDF file as real text, the FontMatrix would not be a
problem, caching would not be an issue. This is probably a large project, but I suspect
less of a pain than this enhancement was.

Caching
========
In gsfont.c is a #define:
#define blimit_LARGE 2500	/* blimit/upper - max size of a single cached char */

Increasing this will allow larger glyphe to be cached. There is another limit in 
gxchar.c:
static const uint MAX_TEMP_BITMAP_BITS = 80000;

This should not be altered. Care should be exercised if increasing the maximum size 
of cached characters as these are emitted in the PDF file as inline images in a type
3 font. The PDF spec recommends that inline images should not exceed 4Kb and some 
consumers may not be able to cope with images which exceed this limit.

Many thanks!

When closing down render threads we check to see if the underlying
allocator had to be wrapped to make it thread safe. If it was, we free the

was accessing memory we'd just freed.

The fix is to move the code that finds the underlying allocator to before
we free the memory.

Revert revision 11901.

Because of the way that PCL draws bitmap fonts directly to the cache there is no 
possibility of making uncached glyphs work properly. Also the code for cached glyphs is
much too forgiving and attempts to add glyphs which cannot be handled. Finally there is 
no provision for type 3 fonts with non-identity matrices. Because the bitmaps in the
cache already have the scaling/rotation/shearing and clipping applied, we cannot have
a type 3 font with a non-identity matrix.

The code will be revised and recommitted.

Fix so that the initial gray color spaces in the graphic state are properly color managed. Previously, if we immediately started drawing in the document with a gray color space, the initial un-managed color space in the graphic state was used and this was not associated with the specified gray source profile.  With this fix we initialize the stroking and filling color spaces to be ICC color spaces associated with the profile for default_gray in the icc manager.  Also a fix for an issue in littleCMS.  When merging profiles, littleCMS will often do an optimization where it approximates 1-D LUTs with an exponent operation for use during merging and interpolation of the profile structures.  If the curve is very steep, as in like a step function, it should not do this approximation.  This was an issue when we had profiles that provided thresholding operations with their 1-D LUTs.   I spoke with Marti about this issue a couple weeks ago.  This commit will create over 6000 differences in the regression test.   I reviewed many of these and they all are minor differences in gray colors as expected.  These are differences where we were drawing unmanaged colors.

pdfwrite enhancement : attempt to make PCL bitmap fonts into searchable type 3

In general pdfwrite only resorts to making a bitmap from a font when it cannot handle
the original font type, which is rare for PostScript, PDF and XPS. However all PCL
bitmap fonts are handled this way.

When this happens, the bitmap is stored into a general type 3 font, a 'bucket' where all
such glyphs are stored. When this font is full, a new one is started and so on. The text
stored in the PDF page stream references the correct type 3 font, but usually the
character code will be unrelated to the original character code.

For PCL bitmap fonts pdfwrite actually starts by creating a type 3 font to hold the 
PCL bitmaps, but doesn't use it. This patch tries to store the bitmaps in the type
3 font where possible, using the character code from the original PCL document. 
Although this will not create searchable text in the general case, it does seem that
there are a good number of PCL documents which do use an ASCII encoding and so will
produce a searchable PDF file.

There are 3 parts to this enhancement:

1) Cached glyphs. When the current font is a type 3 font, and the text operation is
one which might result in an ASCII character code, and we can manufacture a glyph name
for the resulting character code, store the glyph in the type 3 font (rather than the
general 'bucket' font), using the character code and glyph name. Glyphs which can't
be handled this way for any reason are still stored in the general recipient 'bucket'
font.

2) Uncached glyphs. Glyphs which are too large for the cache are rendered as images. The
image handling code has been extensively reworked to try and detect this situation and,
if the criteria for cached glyphs above also holds true, to store the image as a glyph
in a type 3 font and draw text in the PDF content stream instead of an image. Images
which do not fulfil these criteria are still handled as images.

3) Recached glyphs. If the glyph cache fills up, glyphs will be flushed to make space.
If a glyph is then reused we go through the caching case again (for large glyphs which 
are uncached we end up repeating the code every time the glyph is used). We now attempt
to spot this by determining that the glyph in the font has already been used, and rather
than storing a new copy of the glyph, as the old code did, we simply emit text into
the page content stream.

Note that there is a recommendation that inline images in PDF should not exceed 4KB. 
Since CharProcs must use inline images, bitmaps which exceed this size will be rendered
as images, not text (they will also exceed the cache size and so are always rendered
uncached).

In the event that we've decided not to cache a glyph generated by FAPI, we
need to make sure that zsetcachedevice2() doesn't opt to try to cache said
glyph. To do that we were setting in_cachedevice to CACHE_DEVICE_NOT_CACHING
before calling zchar_set_cache(), and setting it back to its previous value
on return. Unfortunately, a font with a CDevProc causes the call to
zsetcachedevice2() to be delayed until after execution of the CDevProc, so
in_cachedevice was (probably) no longer set to CACHE_DEVICE_NOT_CACHING.

Amongst other effects, this caused some anti-aliased glyphs to be render
with incorrect, scaling as well as the potential for marking glyphs to have
empty (but valid) cached bitmaps.

Expected cluster differences: fts_23_2306.pdf at 72dpi shows some (benign)
pixel differences on the pattern filled glyphs - this is actually a behaviour
progression, as it is caused by cache being properly bypassed for an uncached
glyph, rather than the glyph being rendered uncached but the cache receiving
an emtpy glyph.

Previously, for every high level image, the serialized ICC source data was read out of the clist at a different clist file location, which required a fseek, a fread and then another fseek.  This occurred even if all the images shared the same profile.  The cost of file i/o for this can become significant if we have a lot of images.  With this commit, the reading of the profile data is delayed and will only occur if a link using that profile does not already exist in the link cache.

Fix Bug 691727.

Black and White Tiff based devices were not respecting the AdjustWidth
parameter. Fax based devices were applying it regardless, non faxed based
devices were not applying it at all. The documentation says they should
all default to applying it, but be controlled by the option.

In this commit, we change so that all black and white tiff based devices
(except tiffscaled) respect this parameter. We default to applying it in
fax devices, and not applying it in non-fax devices, so default behaviour
does not change. We also update the docs.

Fix Bug 691726, memory corruption in tiffscaled device when
(resolution % DownScaleFactor) != 0.

The problem specifically occurred when the page had 'stray' lines at the end.
The code I had written to cope with this was calling the Tiff writing code
with the wrong row number, causing the tiff lib to try to extend the buffer.
This, it seems, is a bad thing.

Fix bug reported by Norbert Janssen. Inaccuracies in the floating point maths
can cause 'no-scales' to look like 'downscales', and so high level images are
skipped.

This shouldn't actually matter in most cases as the two rendering paths should
give the same results, but when people hook the clist for their own purposes
this can cause problems. The workaround is to introduce a fudge factor and to
accept very slight downscales.

Thanks to Norbert for the first version of this patch.

Fix pdfwrite : Do not emit DeviceRGB/CMYK as an Alternate when disallowed by PDF/A or X

If a /Separation colour space had an /Alternate of /DeviceRGB or DeviceCMYK it was not 
checked to see if it was valid for PDF/A or PDF/X production, if these were set.

As a result invalid PDF/A or PDF/X files could be written.

The code now tests these flags and if the base space is not valid, converts to an 
appropriate base space by; sampling the tint transform function at 0 and 1, converting
the resulting colours to the appropriate base space (using the Red Book methods for
DeviceRGB/DeviceCMYK conversion), creating a new linear interpolation function for
the new base space, using the converted sampled values for /Co and C1.

The new base space is then written to the PDF file.

Add a helpful valgrind header, and call it from gsmdebug.h.

The valgrind header here serves 2 purposes.

Firstly, it insulates us from platforms on which Valgrind does not exist -
if we build without defining ENABLE_VALGRIND then no dependency on any
valgrind headers exists. The standard Valgrind macros are all defined in
this header to do nothing, so they can safely be called in our code
without needing ugly #ifdef ENABLE_VALGRIND wrapping.

Secondly, it insulates us from changes in the valgrind/memcheck.h file -
if ENABLE_VALGRIND is defined we will use whatever version is defined by
the system. If new macros are defined by new versions of valgrind/memcheck.h
we simply need to add new 'empty' definitions to valgrind.h.

To start with, the only use of this code is to mark the contents of newly
allocated blocks as being undefined. Thanks to AlexCher for spotting a
cunning place to do this.

Disable the use of high level images in the clist if we are downscaling;
this serves 2 purposes.

Firstly, it fixes the potential problems with banded/unbanded mismatch
of rendering due to the 'support' calculations done in the high level image
code. These calculations are no longer correct for downscales since the
change to use a simpler interpolated image scaler.

Secondly, when downscaling we will probably end up copying more data than
we would if we just kept the original, so high level images are a bad idea
anyway.

This *should* produce no differences, but actually produces lots.

Most of these might be ignorable (slight rendering differences that appear to
result in the new images being a little lighter, but a significant number
appear to be noticable progressions, which hints that the high level image
clist code is broken. Specifically high level images fail to  render the
same as the non high level code does. In particular halftoning seems to
be enabled for some examples when high level images are used, for no good
reason. This has been opened as bug 691697.

Fix (pdfwrite) : Update CFF interpreter to handle gsubr while searching for SEAC

Bug #691680 "PDF Writer drops many accented characters"

pdfwrite makes use of a routine 'gs_type1_piece_codes' while copying fonts to determine
if a glyph is a SEAC, and therefore includes two subsidiary glyphs. This code was
updated previously (rev 10076) but on encountering a callgsubr in a CFF font, assumed
that the glyph was not a SEAC>

This patch adds support for callgsubr and continues searching glyphs which use a gsubr
to see if the gsubr is actually a SEAC type endchar.

Fix (pdfwrite) : Scale up type 3 font outlines to give more accuracy

Bug #691383, #691287, #691595 various type 3 font problems.

Although this is being fixed for the FreeType implementation, the Artifex font
interpreter had similar problems. 

The issue is caused by using an identity scale at 72 dpi to capture font outlines.
Quark often uses a type 3 font which runs a type 1 font, in order to achieve text
special effects, such as stroke+fill. The stroke was achieved by a 'charpath/fill'
combination, because pdfwrite doesn't have a charpath, this meant that the path was
captured and emitted. Because the scale was so low, the interpreter could run out of
arithmetic precision, resulting in poorly formed outlines.

We can't simply use the CTM in force at the time, as that includes the font scale, but
we need to use something other than the identity. A scale facto of 1000 proved too 
likely to cause arithmetic overflow, or clipping, and also meant writing large values
to the PDF file, which is inefficient. A factor of 10 turned out to be insufficient, so
a factor of 100 has been used.

Because the CharProc is effectively interpreted at the page level, this can result in
large values being used for paths, so we need to scale the device width and height by
100 as well, to prevent clipping (and undo it afterwards!)

Fix (pdfwrite) : Properly scale co-ordinates into Acrobat's range

When emitting various co-ordinates pdfwrite is careful to stay within +/- 32,767 in
order to ensure all versions of Acrobat can properly deal with them. To achieve this it
emits a matrix which scales values up, and then writes the co-ordinates scaled down
by this factor. Thus ensuring that they stay within permitted values, but are still
correct.

However, when emitting a rectangular fill, the scale was applied backwards, the 
co-ordinates were scaled *up* instead of down by the scale factor. This led to wildly
incorrect values being written for rectangular paths.

No differences expected with this in the test suite, however it forms part of the fix
for type 3 fonts which will follow and does rely on this change.

Update interpolation filter. When we are downscaling an image on either axis
we now use a simpler (less computationally complex) linear interpolation
filter rather than the existing mitchell filter.

For downscaling the difference in quality between mitchell and simple
linear interpolation is not that noticable. (But the CPU/memory usage is a
quarter what it would be for proper mitchell downscaling).

What is noticable is that the existing downscaling code is 'bent' to avoid
having to hold more than 8 temporary scaled scanlines of the image. The effect
of this is to incorrectly limit the pixels that actually go into contributing
to an output pixel, producing dropouts.

We update the code here to remove this limit. This means that downscales
may potentially take more memory and more computation to perform, but the
overall quality is better.

Regression tests show both noticable and unnoticable differences in files that
enable interpolation (270 or so). The noticable differences are all that the
new output looks smoother, at the expense of losing some contrast and solving
some 'jaggy' looking edges.

Testing with my custom dropout test file shows a huge improvement with the
new code. I'll add this to the test repo shortly.

Fix for a large memory leak that can occur when a pattern cache entry is freed and a transparency buffer exists in the entry.  A problem was that the pdf14 device, which contains pointers to the buffer, had its close device procedure set to forward due to the device being set in a disabled state during pattern_paint_finish.  The close device proc for the pdf14 device contains the calls to actually free the buffers so this was not occurring (instead we were forwarding to another device).  In addition, the pdf14 device itself was not being destroyed.  With this commit, when the pattern entry is freed, the  pdf14 device is now closed, which frees the buffers, and the pdf14 device is properly reference count decremented to result in the device itself getting freed.  Regression run revealed no problems.

some output, even just a notdef glyph. So in the non-hinted, and notdef
fallback cases, remove the "tricky" flag from the Freetype face.

No cluster differences expected.

Fix (pdfwrite) : Process text in Tr 3 even if the Widths are non-standard

Bug #691605 "Invisible text not preserved by pdfwrite"

The problem was that if text in text rendering mode 4 (neither stroke nor fill) used a
font where the entries in the FontDescriptor /Widths array did not match the actual 
widths in the font, the code took a path where the glyphs were not added to the 'used'
list, and so were never emitted.

Text in regular fonts where the /Widths array was missing, or matched the widths in the
font (as the spec says they must) worked correctly.

Fixed by processing text whose operation properties include TEXT_RENDER_MORE_3 the
same as text with the TEXT_DO_DRAW property.

Fix (pdfwrite) : Check encoding compatibility when finding base fonts

Bug #691656 "crash in Chinese font: /typecheck in --.FAPIBuildGlyph--"

A typecheck error is not a crash of course, but when using the built in font interpreter
this did not produce an error, silently discarded the text instead. This was still
incorrect.

The problem is caused when dealing with type 0 fonts and producing multiple type 1 fonts
to handle the large number of glyphs. The code for finding an existing font (in order
to minimise the number of new fonts) or create a new font, did not consider the 
encoding of an existing font when trying to match it (this did work for regular fonts).

This could lead to a font with an incompatible encoding being used, which caused an
error later in text processing where a routine is supposed to be guaranteed no font
encoding problems. That led to an attempted fallback to the 'bitmapped type 3 font'
solution, but the text processing was passing ridiculous values to the font interpreter.

In the old font code this caused a silent discard of the text, with the FreeType code 
it produces an error.

Fixed by checking the base font we find to see if its encoding is compatible with the 
current text encoding, and manufacturing a new font if it is not.

No differences expected.

Put back some statements. It turns out that we can either have gcc be warning free or
the static analysis warning free. The problem is gs_note_error which uses
gs_log_error, on a release build gs_log_error is defined as the error value. 

If we don't do something with that value then gcc complains that the 'statement has no
effect'. So the code was set like this:

ecode = gs_note_error(error code);

But if we want to actually ignore the error and just note the problem, then we don't use
ecode and the static analysis complains that the variable is unused....

Fix for part 1 of bug 691484 - uninitialised memory usage in clist code.

The FAPI code copies bitmaps and pads them out so that each raster line
is appropriately aligned. Previously the padding bytes were left
uninitialised. Unfortunately the clist code reads the padding when
compressing the bitmaps, which a) upsets valgrind and b) means that the
exact size of the clist will vary from run to run.

Here we tweak the copying code to ensure that the padding bytes are always
set to zero.

No differences shown in local cluster. This solves part 1 of the bug.

Fix (pdfwrite) : ConvertCMYKImagesToRGB not working

Bug #691647 "-dConvertCMYKImagesToRGB no longer works"

Originally caused by the conversion to the ICC workflow, which meant that all images
appear to be in a ICC space, and only images originally natively CMYK are converted.

Probing the ICC space using the provided utility to return the original colour space 
allows the code to work, but reveals a more serious error. The code in
psdf_setup_image_filteres() alters the image colour space and decrements the reference
count of the original colour space.

This seems logically correct, and in one of the three calling paths it is correct, but
under one of the other two conditions it causes a crash. The routine 
pdf_begin_typed_image_impl() makes two copies of the original image parameters, and
when it does so it does *not* increment the reference counts of any counted objects.
This copied data is presented to the image filter setup several times, and if CMUK
to RGB conversion is going on the original colour space is decremented each time. This
leads to obvious problems.

The simplest solution would be to increment the reference counts when the copy is made, 
but that would mean checking all the error condition break outs, and decrementing the
reference count in each case.

Since the colour space is only decremented in the filter setup, this patch increments
the count before the call, and if the colour space is the same afterwards (whether
an error occurred or not) decrements it back again. If the colour space changes we do
not decrement the space of course, as the filter setup routine has done that.

In addition, extended the test for whether CMYK images should be converted to include
the original test of the native space, in case we get here after an image has been
converted to a base space and no longer has an ICC space.

No expected differences, this configuration is not tested by the regression suite.

Fix (pdfwrite) : allow for UserPasword and OwnerPassword in page device

Bug #691256 "OwnerPassword and UserPassword don't work as device parameters"

pdfwrite sets up encryption filters when the device is opened, and the device is not
(currently) closed until Ghostscript shuts down. This means that changes to the page 
device dictionary which require a restart (eg the encryption parameters) do not affect
the current setup, though they may be (incorrectly) written when the device is closed.

This patch addresses the specific issue of OwnerPassword by closing the device if the
password is changed *and* we have not yet written any pages. If we have already begun
the output when a password change occurs then we ignore it and flag a warning.

This is also a first step in the direction of making pdfwrite open and close properly
so that we don't need to restart Ghostscript to use it.

Fix (pdfwrite/ps2write) : Don't dereference mask colour spaces

Bug #691106 "-sDEVICE=pdfwrite -dConvertCMYKImagesToRGB=true"

When checking to see if an image needs to be converted to RGB, the image space is
checked to see if it is CMYK. However an image mask does not have a colour space (it
is NULL), firstly so that we can tell its an image mask, and secondly because masks
genuinely do not have a colour space, they take on the current colour.

Attempting to dereference the NULL colour space causes a crash. Since a mask never
needs converting to RGB, we short circuit the test by detecting a NULL colour space.

Bug #691088 This does not affect the PostScript/PDF interpreters which now use FreeType
but is relevant still for XPS and PCL.

A buffer was allocated to contain the GSUB table from the TT font, but was never freed

length' array and added a notification procedure which is called when the font is 
released, and that procedure frees the GSUB buffer.

Fix so that objects tag information makes it through transparency rendering AND the clist.  An issue was that the pdf14 encode and decode procedures are used as opposed to the target device encode and decode procedures and it is through a value in the color index that we currently communicate the object type through the clist.  When we are in page rendering mode, it is easy to get the current object from mem->gs_lib_ctx->BITTAG, but this is not set correctly in clist rendering if for example a glyph is stored in the clist as a mask fill.  Instead the information about the object is extracted from the color index.  So, to make this work, we had to introduce an encode method for the pdf14 device that incorporates the tag information and also make sure that the bit depth for the pdf14 color info value is incremented appropriately so that the extra byte is stored and extracted from the clist.  The object type is then recovered during the pdf14 mark fill rect procedure.  This was tested with the updated bitrgbtags device using a custom file that has overlapping text, image and path objects with varying transparency amounts.

Final part of the fix for bug 691612.

Currently the code blindly sets the "lop_pdf14" whenever the pdf14 device is
in use. This forces the 'lop_is_idempotent' test to fail, which in turn forces
slower cases to be taken through the code.

This patch alters that logic, so that the pdf14 device can leave that bit
unset if the parameters are set up in such a way that the lop really can
be idempotent (i.e. normal blending, solid alphas etc).

This vastly improves the speed of rendering non-alpha content, so we are no
longer penalised for having just a small amount of transparent content on a
page.

Testing shows 398 files that change, but bmpcmp reveals these all to be very
small changes to do with whether individual pixels are filled or not. This
is consistent with the typical mismatches between special case and normal
renderings, so can safely be ignored for now.

As part of the investigation into bug 691612, we noticed that the clist
band playback code doesn't call the device stroke_path method, but instead
calls the default implementation directly.

In order the fix the bug, we'd like it to call through the device version
(pdf14_stroke_path). Consensus is that it's an oversight that it's not calling
the device version already, and tests indicate no differences (*) so this
patch changes it to call via the vector.

(* Actually regression testing shows 2 pdfwrite differences, but they are
in unbanded tests, so can't be executing this code, so are probably just
indeterminisms).

Fix (pdfwrite) : Do not write Encodings with Symbolic TrueType fonts

Bug #690744, #691036, #691319. The PDF specification makes it clear that Symbolic
TrueType fonts should not have a FontDescriptor which contains an Encoding entry.
pdfwrite has specifically been doing this, the reason being (code comments) :

	 * We write True Types with Symbolic flag set.
	 * PDF spec says that "symbolic font should not specify Encoding entry"
	 * (see section 5.5, the article "Encodings for True Type fonts", paragraph 3).
	 * However Acrobat Reader 4,5,6 fail when TT font with no Encoding
	 * appears in a document together with a CID font with a non-standard CMap
	 * (AR 4 and 5 claim "The encoding (CMap) specified by a font is corrupted."
	 * (we read it as "The encoding or CMap specified by a font is corrupted.",
	 * and apply the 1st alternative)). We believe that AR is buggy, 
	 * and therefore we write an Encoding with non-CID True Type fonts.
	 * Hopely other viewers can ignore Encoding in such case. Actually in this case 
	 * an Encoding doesn't add an useful information.

Since this is working around a bug in old versions of Acrobat, and the presence of an
Encoding causes preflight errors and is specifically forbidden in PDF/A, this work
around has been removed. I would like to check recent versions of Acrobat to see if 
this issue persists, but am unable to find an example file. The change predates the
adoption of Subversion, the first logged change is October 2003.

Addition of support to enable persistence of objects tag information through transparency rendering.    In the current code base, transparency blending erases all knowledge about the objects that were drawn and blended, setting the entire object to image type.   With this commit, the tag information is retained through blending by doing a bit-wise or of the tag values.  When a device supports tags, the pdf14 device will create an additional plane to maintain the tag data information.  Blending of the tag information occurs in pdf14_mark_fill_rectangle, pdf14_mark_fill_rectangle_ko_simple and pdf14_compose_group.   A new device procedure called put_image is added.  This is called by the pdf14_put_image operation, which enables the communication of the tag information to the target device.  pdf14_put_image will first attempt to pass the alpha channel and the image data not scaled by the alpha channel and the tag data to the target device.  The planar offset location of the alpha and tag data is communicated in the put_image procedure interface.  If the target device cannot handle this form of the data, it should return 0.  The pdf14_put_image operation will then blend the alpha data and attempt the put_image again but this time with an alpha offset of 0 to indicate that there is no alpha data.  Note that the alpha data remains valid for those devices that still want the alpha but also want to have the graphics library do a premultiplcation of the alpha with the data.  Details of this interface will be added to the documentation.  In addition, the bitrgbtags device is being updated to demonstrate the use of the put_image procedure.

Another partial fix for Bug 690993. The sole remaining Valgrind warning
is that memcpy is called on overlapping src/dst blocks in cmd_read_data.

Investigation supports this, and suggests that we should be using memmove
instead. This does stop the error, and leaves us valgrind warning free.

This also appears to resolve the indeterminism, in that repeated runs
of the command line given in the bug return identical results.

The bug remains open though, as there is still a mismatch between banded and
non-banded mode.

Partial 'fix' for Bug 690993. When encoding a bitmap into a clist, we
copy it into a block with potentially larger padding requirements. These
extra padding bytes were left undefined, causing subsequent attempts to
compress the bitmap to cause valgrind to give warnings.

The fix is simply to introduce and use a new function that copies a bitmap
and zeros the padding. This should eliminate the warnings, produce better
compression, and (more importantly) mean that every run uses the same amount
of memory, hence eliminating potential odd effects where clists may be of
different lengths on different runs.

This still leaves bug 690993 open.

Fix (ps2write) : Bug #689419 "Text missing if nested BT with opdfread.ps"

Type 3 fonts which select another font and then draw text from it (a common feature of
Quark Xpress) can result in nested 'BT' operators when processed by ps2write.

The opdfread prologue does not cater for this, specifically the TextMatrix is not saved
and restored around a BT/ET pair. If the text matrix is altered by the font
selection, then the 'ET' will not restore the old matrix leading to incorrectly sized or
disappearing text.

The patch (supplied by SaGS) saves the TextMatrix in a stack (stored in an array) and
restores the matrix after an ET, in case it is nested. Currently this allows for 
nesting up to 20 deep, which should be more than adequate. Note that if we were to 
encounter a nested BT with no ET this would still fail, but in this case the file 
produced by ps2write would be invalid, and the missing ET should be fixed.

No differences expected, the regression suite doesn't test ps2write.

Fix (pdfwrite) : Don't colour convert SMask images

Bug #690612 "PDF sRGB conversion loses images"

The handling of SMask images in pdfwrite is a bit convoluted. These are handled by 
converting initially to a DevicePixel colour space, then detecting that later and
replacing with a DeviceGray space. However, after doing so, if ColorConversionStrategy
was set, the space (and image samples) would be converted to another colour space. This
is not legal for SMask images.

This code simply checks to see if the image is an SMask before setting colour conversion
and doesn't convert the colour space/samples if it is and SMask.

No expected differences.

pdfwrite enhancement : performance improvement with type 3 fonts

Bug #690575 "PS to PDF Conversion extremely slow (possibly endless)"

The type 3 font code assembles CharProcs for type 3 fonts by writing them individually 
into a 'cos_stream'. Each time a new one is completed it is compared to all the existing
CharProcs to see if it is a duplicate. This was done by fseek/fread/memcmp operations.

As the number of CharProcs increases, the time spent seeking, reading and comparing
the data increases dramatically and performance becomes very poor. Not only that, but
the test is actually done twice for each new CharProc.

This patch tackles the problem by creating an md5 hash of the data written to a 
cos_write_stream (a subclassed cos_stream) as it is written. The cos_stream 'equal'
routine checks to see if the md5 hash is valid and if it is then compares the hashes.
If the md5 hash is not valid (ie not a cos_write_stream) then it uses the old 
seek/read/compare mechanism. This will improve the performance of any stored data
if it is stored using a cos_write_stream and compared against other data of the same 
type. (I don't believe we do this anywhere else currently, but I'm not suer)

This does improve the performance significantly, and the code no longer spends most of
its time waiting for I/O operations to complete. It is still slow, but this is the 
result of using lots of type 3 fonts. Because of the way these must be processed in 
order to capture the outlines they are never going to be fast.

In my test this runs 2-3 times faster than before. There should be no differences in
output from the old code.

Bump version number to 9.01 and associated changes.

[base/gscdef.c base/version.mak Resource/Init/gs_init.ps]

Version 9.00 (2010-09-14)

This is the first release in the stable 9.x series.

This release includes a move to an ICC-based color rendering workflow. The design allows easy integration of 3rd party color management modules (CMMs) and management of DeviceN and spot source colors with ICC profiles as well as with non-ICC proprietary methods. The default CMM is the well known littleCMS. Postscript color objects and non-ICC CIE-based PDF color spaces are converted to equivalent ICC profiles enabling complete color management for all color spaces by an ICC-based CMM. New command line options enable the specification of gray, rgb and cmyk default ICC profiles as well as output device ICC profiles. The new work flow provides performance improvements in the rendering of images, shadings and transparencies. In addition, the color conversions are designed to work efficiently in multithreaded display list (c-list) rendering through the use of a shared link cache. Finally, proper ICC based rendering now occurs for ALL XPS objects including Named colors, N-Channel colors and images with internally embedded ICC profiles.

The second major change in this release is that glyph rendering for all font types except Type 3 is now handled by Freetype (via a much improved and enhanced Font API). The most obvious benefit of this is a complete, and proven implementation of the TrueType byte code interpreter (now unencumbered by patents).

Another major change is that the Postscript interpreter's graphics state now stores two separate colour space settings for stroking and filling, to better support the stroke and fill colours required by the PDF interpreter.

Finally, support for optional content has been added to the PDF interpreter.

This release also includes a number of improvements to the pdfwrite device to improve reliability and quality with PCL and XPS input. Many improvements to the support of JPX images in PDF files, PDF annotation rendering and the usual number of general bug and robustness fixes.

For security reasons, Ghostscript no longer searches the current directory by default. Use -P option to revert to old behavior.

Another revision of the FAPI code. Due to a problem in Freetype which needs
further investigation, we cannot produce an outline, then decide to produce
a bitmap if it is small enough. We work around this by producing a bitmap,
and if it is too large, dispose of it, and retry with an outline, thus although
we still risk larger than ideal memory use, it is very short lived. A glyph
too large to be cached (for which we will now usually use an outline) does
not suffer from the Freetype issue mentioned above.

The maximum allowable bit for Freetype to produce is now 1.5 x the maximum
cache bitmap as set in the Postscript state - it is set larger than the
cache bitmap since it is *vital* that if GS expects a bitmap to be cache
we supply a bitmap. Given that the bounding boxes arrived at the GS cache
device and the Freetype rendering code arrived at slightly differently, there
would be the chance of edge cases where FAPI would produce an outline, when
the cache expects a bitmap. Allowing FAPI plenty of leeway avoids that.

The calculation to convert a quadratic to a cubic spline in the
Freetype interface code was slightly wrong.

Also, FAPI now sets the fill adjust to 0 for filling outline glyph, instead
of inhereting the value from the originating graphics state, which gives
*much* more consistent output between the bitmap and outline cases, and
addresses the slightly excessive boldness observed for outline glyphs since
the adoption of Freetype/FAPI as the default font scaler/renderer.

Finally, support for the existing Ghostscrit text anti-aliasing
capability is improved.

Fix to enable proper mask filling with patterns that have transparency.  Major change is in gdevp14.c where begin_type_image and mask_fill procedures now will (if we are filling with a pattern that has transparency) push a transparency group.  When we are finished processing the image, the group is popped which enables proper blending.  There remains an issue with a special file that Ken created when it is run in c-list mode.  A new bug will be opened for this issue.  Thanks to Ray for helping with this project and finding a bounding box issue in the creation of the transparency group during c-list reading.

Fix (pdfwrite) : incorrect pattern matrix calculation

Bug #690504 "ps2write does not work with asymmetric resolutions, like 600x1200dpi "

The problem was caused by frankly totally incorrect calculations when generating the 
/Matrix for a pattern. Because we always see the CTM including the resolution scaling
but need to output a matrix with this removed, we scale the CTM by the inverse of the
resolution scaling.

But the calculation simply divided the CTM through by the scale factors, which is
totally incorrect and fails badly if the matrix involves rotation. The code now
correctly creates and multiplies a scale matrix. Note, the order of multiplication is
important here.

No differences expected.

Slight refinement in the how the FAPI character generation detects we are
producing anti-aliased glyphs.

Also, it seems that when assigning variable value to a second, larger data
type, whilst gcc promotes the data type before the assignment, MSVC promotes
the variable later, so shifting a 32 bit integer up during an assignment to
a 64 bit integer variable works find on gcc, but MSVC loses the most
significant bits. So we need to force the promotion to happen with a cast.

Some fairly substantial changes to the FAPI code to get very high resolutions and
anti-aliased text working reliably.

For AA text, we now make *sure* to produce outlines for non-cached glyphs, thus
the GS path code can anti-alias correctly (for cached glyphs, the "show" machinery
does the anti-aliasing from the cache bitmap).

The high res problems were highlighted by the bbox device (which runs at 4000 dpi).
To resolve these the width and height parameters for Freetype had to have value
overflow compensation added, to match the existing underflow compensation.

FAPI/Freetype also now will only create a glyph bitmap if the bitmap size is smaller
than the allowable glyph cache bitmap. It may still produce a bitmap for a non-cached
glyph, if the cache is full, but the individual glyph bitmap is not larger than the
allowable glyph item - this is allow for better consistency when we're near the limit
of the total cache size.

Finally, the FAPI outline retrieval code now requires 32.32 fixed point variables (rather
than the previous 16.16), which prevents overflow, and improves accuracy. If also provides
us with the opportunity to check for overflow/underflow of the GS internal fixed point
variables, before calling the GS path code.

There are quite a few cluster changes. I have checked them all, and one is a progression
(missing glyphs now render) and the rest are the pixel level differences expected by
having GS render a path, rather than Freetype - most are due to Freetype grid fitting to
the glyph bitmap, and GS grid fitting to the page raster.

Fix (pdfwrite) : string not being re-encoded

Bug #690441 " Files render properly with gs, but are misformatted by ps2pdf"

A Coverity fix in revision 9072 prevented a crash, but also circumvented code that was
essential to run under some conditions. (This is described by comments in the code as a
'trick'). The routine created a text string with the encoded text for a font with a
custom encoding derived from a CIDFont with an unusual CMap.

In order to avoid the potential crash, but still re-encode the string, which is
essential, the relevant portion of the code has been copied and is exercised instead of
executing 'pdf_reserve_char_code_in_pdfont()'. This produces the reencoded string we
need, but if the encoding fails, where we would have caused a crash by dereferencing a
NULL pointer, we instead return an error.

No differences expected, we obviously don't have a test case in the regression suite.

pdfwrite enhancement

The addition of code to test and honour the 'embedding flags' in TrueType fonts has
led to problems because PostScript producers are embedding type 42 fonts in the
PostScript which are non-embeddable and worse use a custom non-reversible encoding,
so that the  resulting PDF file has garbage text when a normally encoded font is used
as a replacement.

It seems that Adobe has published a 'white list' of fonts which have been granted
at least some embeddable rights. It isn't obvious if these are fonts which were type
1 (and therefore could be converted to TrueType and get incorrect embedding rights) or
if the fonts were originally released as TrueType with the wrong embedding rights.

In any event, this list has now been added to pdfwrite; if a font is encountered which
has restricted embedding, then its name will be checked against this list, if it is
found in the list then it will be considered as embeddable. We have already 
encountered one font on this list which has a slightly different name to the original
(a space was removed) so spaces in the font names are ignored. 

This list will have to change over time, and we may find other examples of characters
which we want to handle specially (eg oumlaut treated as o and e)

No differences expected as this is not tested in the current regression suite.

Fix (pdfwrite) : linewidth corruption when Tr is 1

Bug #690436 " (regression) re-distilling pdf causes R graphics to go block-single-color."

The problem was cause din the pdfwrite-specific text rendering routines. When the text
render mode is 1 (stroke), the linewidth is adjusted by the current text matrix. However
the routine to do this is called each time any element of the text 'graphics state'
changes. So if multiple calls to (eg) Td were made, the linewidth would be altered
even though there had been no change in 'w'.

Fixed by getting the current linewidth before the text rendering routine, and setting
it back to this value after the text rendering routine.

No expected differences. However z400454b01d4-1.pdf seems to exhibit some minor
differences which I am unable to reproduce locally. They are so minor that bmpcmp
ignores them, and on my tests the PDF files are identical bar the date/time stamps
and other metadata. I don't believe this is a real difference.

Fix (pdfwrite) : faulty matrix transformations for Pattern dictionaries

Bug #690398 "Geometric issue with pattern"
The problem is the definition of the default co-ordinate space. When a Pattern is at the
page level or drawn inside a form, we need to remove our 0.1 scaling in order to return
to the 'default co-ordinate space'. However, when painted on a form nested inside a
form, the default co-ordinate space is the parent form, so we don't need to undo
the scaling. 

This is the same problem addressed for shading dictionaries in revision 11347.

Fix (pdfwrite) : FormDepth not tracked properly.

Part of the fix for Bug#690398. In order to know whether a pattern matrix should be
converted to the top level CTM, or to an enclosing Form CTM, we track the Form Depth
by noting when transparency groups begin and end (currently this is the only way to get
a form output by pdfwrite).

There was a problem with mask groups, because although pdf_begin_transparency_mask calls
pdf_begin_transparency_group, pdf_end_transparency_mask doe snot call
pdf_end_transparency_group. This resulted in the depth being incremented at the start
of the mask, but not decremented at the end, so patterns could be emitted at the page
level but with the CTM for a Form level, leading to missing content.

Fixed by decrementing the FormDepth appropriately.

Enhancement - Font copying (pdfwrite)

Bug #691573 " invalidfont in xshow". The file does in fact contain an invalidfont, the
type 42 embedded fonts are defined by adding /.notdef to the CharStrings dictionary as 
if it were the Encoding array. The key /.notdef is added 256 times with values ranging
from 0 to 255. Of course only the last one is actually defined.

This means that when we come to copy the /.notdef glyph for our font copy, the type 42
GID is 255. However the font does not contain a glyph with GID 255, so the copy of the
font fails.

Although this is an illegal font, Adobe Acrobat Distiller does produce a PDF file from
it. In order to duplicate this, code has been added when copying a font. If we fail to
copy a glyph, and the glyph is /.notdef and the GID is non-zero, we try to copy a glyph
with GID 0 instead. If that fails we error out, otherwise we use the glyph with GID 0.
(TrueType font /.notdef glyph has GID 0)

This works for the supplied file but is not, of course, a guaranteed solution since 
another badly formed font may not contain a glyph with GID 0.

Fix (pdfwrite) : errors in XMP metadata parsing

Bug #691562 "ERROR -15 closing pdfwrite device".

This use of a DOCINFO pdfmark exposed 3 separate bugs in pdfwrite's handling of XMP
metadata.

1) Decoding an escaped PostScript string. Unescaped characters and octal escapes worked
correctly, but non-octal escapes moved the index into the string one place too many.

2) The escape '\b' (backspace) wasn't handled and returned incorrect data. Although not
tested by this issue, the form feed (\f) also wasn't handled.

3) When converting UTF16 data to UTF-8, the end of the destination (UTF-8) buffer was
calculated incorrectly, causing a spurious buffer overrun error.

The code now handles the missing escapes, does not advance the character position after
decoding a non-octal escape and correctly defines the end of buffer. After this the
Title string displays the same in Acrobat as the same pdfmark sent through Adobe
Distiller.

No expected differences as this only affects the document metadata.

The "shortcut" for rendering masks use by the FAPI code for uncached
glyph bitmaps (gx_image_fill_masked) is only safe, in the general case
when drawing "plain" colours to the output. For complex colour spaces
(like patterns) we must use the "long hand" version.

This causes minor pixel level differences in some cluster tests (due
to rounding differences), and some (very small) progressions: there
are differences in about 20 cluster jobs.

Enhancement : pdfwrite

performance enhancement for pdfwrite when handling files with large amounts of text.

Bug #689859 "Performance comparison versions 7.07 and 8.62 on HP-UX ia64" Alex's
analysis shows that pdfwrite was spending a lot of time trying to to see if two type 1
fonts were the same before deciding whether a glyph could be added to a font, or was 
already present in a font copy.

Most of the time was spent extracting and comparing /Subrs. The new code creates a hash
(MD5) of both the local and global Subrs (if present) and stores that in the type 1
'data' field in the font (16 bytes). The hashes are created by pdfwrite only as they 
are required, so there is no performance penalty for rendering. The hash comparison is
considerably quicker than the long winded Subrs comparison.

For many files the performance difference is minimal but for file containing lots of
pages, mostly composed of text, there is a considerable saving. The text files run in
about 60% of the time they did before this change.

The "show" machinery expected that even non-marking text operations
(such as stringwidth) would result in a glyph bitmap which
could be cached (assuming the glyph would be a candidate for the
cache with a normal marking operation, like show).

FAPI, however, did not create a glyph bitmap for non-marking
operations, thus the cache would receive a valid, but
"empty" glyph. This caused Postscript that used stringwidth
before a show to sometimes "lose" glyphs, by using the empty
cached glyph.

FAPI's behaviour now matches the expectations of the show/cache
management code.

Causes cluster differences in Bug688372.ps, fts_31_3111.pdf, and
14-08.PS, these are all progressions.

Fix (pdfwrite) 
A piece of data (pointer to glyph data) was stored and passed into a routine
'process_text_modify_width' which expected the glyph data to remain unchanged but
modified the text enumerator data. This doesn't work if the glyph data is a pointer
to the text enumerator data. NB the text enumerator is saved and restored around the
call.

Modified so that the calling routine makes a copy of the glyph data before calling 
'process_text_modify_width'.

This should prevent 13-10.ps from entering an infinite loop.

Fix for Bug 691504 (gs taking a long time to render a file).

Revision 8694 changes code from using a simple cast to an int to using
a call to (int)floor. This fixes problems, but costs a factor of 3 in
processing time for heavily tiled files.

Here we change to using a macro version of floor instead. This removes
the function call and NaN handling overheads and returns us to the
same kind of performance as we had before.

We apply the same change throughout the file (i.e. all the calls to (int)floor,
not just the two changed in r8694.

There is still scope for optimising this code further, but this closes the
regression.

Fix for bug 691488.

This commit fixes the issues that we are seeing with the JPEG2000 images in the FTS files EXCEPT for the issues related to SmaskInData.  Those images will be addressed in a separate commit and will now be handled in bug 691470.  

With this commit, support is in place for faster 16 bit image rendering due to the improved ICC support, which lets us avoid the multiple conversions from 16 bit to frac to float to unsigned short to byte which occurred in the old flow.  Also, the jasper interface will now, when it encounters a 16 bit or 12 bit image, use the higher bit depth renderer and pass the data along.  Previously, we were truncating to 8bits in our jasper interface.  These changes have been regression tested and checked with bmpcmp.

Assorted fixes for the modularized X11 output device

All object files destined for shared libraries needed to be compiled
with -fPIC but this is not the case for gsparamx.c, gdevemap.c, and
gdevxcmp.c which are required by other parts to be built as standard.

This change makes x11 not depend on gsparamx.c and gdevemap.c (and not
geeting them included in the shared library X11.so). gsparamx.c is
part of psdf and is usually included and available, and gdevemap.c is
small enough to be inserted completely where it is used.

gdevxcmp.c is addressed by building it with $(GLCCSHARED) and not with
$(GLCC).

In addition, $(CC_SHARED) is only used for object files, rather than
for linking, so DYNAMIC_CFLAGS is more appropiate here than
DYNAMIC_LDLAGS.

Fix (pdfwrite) : try not to write out invalid xref

Exposed by bug #691503. There are circumstances under which we create a reference to a
/Page object which does not yet exist (creating an outline tree for example). In this
case we create a reference to the page, and set its initial offset to the current 
position in the PDF file. When we later write the real object we update the position
to reflect the point in the file where it is actually stored.

However, if we don't actually ever write the object (in the case above, because
LastPage is set before the destination page), then the object remains pointing to the
wrong location in the file. This is then written into the xref table, and this confuses
the current version of Ghostscript.

The patch creates new pages with an offset of 0 (which is always invalid because the 
PDF header means the minimum offset for any object is 15). If the page is later
created then the offset gets updated. If it is not written, however, we now check in 
the xref writing code to see if an object has an offset of 0. If it does, then we
break the xref table up and do not write an xref entry for the missing object.

Ghostscript is happy with this and processes the file.

NB the proper fix is to not emit the Outline entry for the page which will not be
present in the output, and a patch has been suggested to achieve this. This code has
some uses, however, as it may prevent this kind of problem in the future. It also
permits objects to be created and never referenced (presumably because they are never
used) without leaving invalid entries in the xref, which might be useful.

No expected differences.

Two changes for two primarily pdfwrite problems with FAPI/FT.

The first is to only replace whichever of BuildGlyph or BuildChar
procedures the original font actually contained, replacing both
regardless confused some of "decoding" code elsewhere in GS
(op_show_continue_dispatch()) and we ended up receiving a valid
glyph to render instead of notdef. In this case we ended up incorrectly
stroking a charpath (this was seen with Quark's Type 3 "special effects"
font). With rendering output this resulted in a boldening effect on the glyph,
in pdfwrite, the result was strange extra lines through the glyph.

The second change is to due pdfwrite's use of a unit matrix for some of
its work. This resulted in small glyph metrics rounding to zero within
Freetype, and pdfwrite thinking a glyph had a width of zero. So make
the scale value at which we consider a glyph to be "small" an order of magnitude
larger, which gets compensated for in the calculation of Freetype's final
matrix.

Unfortunately this does cause ~2600 differences in the cluster tests: some
are progressions, most are pixel differences due to rounding differences
because the scaling numbers have changed in Freetype.

Fix bug #691493. Revert some of the work done for gs_2_colors.

I had needlessly attempted to have 2 pattern_cache's, one for stroking
colors and one for non-stroking colors. Given that the pattern_cache is
indexed by color id number, this is not necessary as all the data can
live happily in just one instance.

This removes the problem seen in the bug (where it was getting into an
infinite loop trying to populate the cache).

Local cluster testing shows this produces 57 differences, all (I think)
non-determinisms.

CUPS Raster output device "cups": Improved support for rendering jobs with high memory demands.

Let Ghostscript determine the memory buffer sizes automatically (as it
does with all the other output devices) if the environment variable
RIP_MAX_CACHE is not set, zero, or does not begin with a number (like
"auto"). If RIP_MAX_CACHE defines a valid value, use the actual value
for BufferSpace and not 1/10 of it. MaxBitmap is the maximum buffer
size to be used when rendering in full page mode, BufferSpace is the
buffer size used in banding mode. Banding mode is used if MaxBitmap is
too small to hold one page. Bug 691499.

Add new gp_thread_start, gp_thread_finish abstraction, and deprecate old
gs_create_thread function. Adapt multiple rendering thread code to use
this new style instead. Hopefully this should solve the problems seen
in rare cases when a test thread doesn't get scheduled until after the
DLL has exited and the code isn't around any more.

No expected differences.

This code has been tested with MSVC and on linux with pthreads. While it
should work with Borland and Watcom (as all the headers appear consistent)
I have not been able to properly test it. Therefore the code is currently
configured to fall back to the old code, thus hopefully guaranteeing that
this commit won't make the operation under Borland/Watcom any worse than
it is now. This fallback is controlled by a single define for each of
these systems in gp_wsync.c, so it's easy to test. If users can report
success with the new code we can remove the fallback trivially.

alignment as Ghostscript expects, so in the event that is the case, create

further operations on it.

Fix for bug 691478

Note that string objects that are maintained as user params must be either allocated in non-gc memory or be a constant in the executable. The problem stems from the way userparams are retained during garbage collection in a param_list (collected by currentuserparams).  For some reason this param_list does not get the pointers to strings relocated during the GC. Note that the param_dict itself is correctly updated by reloc, it is just the pointers to the strings in the param_list that are not traced and updated. In this particular case, ICCProfilesDir sets a string in the icc_manager. When a reclaim occurs, the string is relocated (when in non-gc memory and when it is noted to the gc with the proper object descriptor).  Then if a set_icc_directory occurs, the user params pointer has NOT been updated and validation problems will occur.  Fix for this was to make the string not known to the GC and to allocate in non-gc memory.  When icc manager is deallocated, the string is also deallocated.

Update trunk to FreeType 2.4.1

The important change (from Ghostscript's point of view) is that the previously
patented TrueType hinting operations have been enabled by default after the
expiration of the patents in question.

This change (the hinting being enabled) causes 3060 non-pdfwrite cluster
changes, and 655 pdfwrite changes - these are expected, and are
progressions.

Fix the bug that prevented recognition of GenericResourceDir/Category/Name
as a valid resource path and required inclusion of GenericResourceDir in
the search path to find the same resource by searching.

New procedure does the following:
1. Returns GenericResourceDir/Category/Name if it exists.
2. Searches for Category/Name in LIBPATH. Returns actual path if found.
3. For non-existing resources return the same path as (1).

Old implementation added GenericResourceDir twice, didn't close files,
used system memory, called expensive procedures twice, etc.

Regression testing shows trivial differences in 23-07.ps, which prints
the length of ResourceFileName procedure.
This is a partial fix for bug 691408.

Improve Ghostscript operation when current directory is not included in the

   the number of trivial configuration errors.
2. Search LIBPATH list for valid iccprofiles/ directory as a sibling to
   (Resource) and set it as a default to ensure a valid default.
   This code follows /GenericResourceDir example.
3. Make sure that the path name derived from /GenericFontDir is is not
   searched but other font file names are searched. Earlier code relied on
   a feature of .libfile not searching for an absolute path and failed
   when the path was relative.

Improve Windows batch files.
Bug #691440 "Windows bat files use relative paths and write to non-temp dir"

As suggested by Bjorn Martensson in bug #691440. Altered all batch files which call
other batch files so that they prepend the call with the location the original
batch file was executed from. This allows batch files such as ps2pdf.bat to be called
from locations other than the Ghostscript 'lib' directory.

Also altered the location of temporary files created by the batch files to the Windows
temporary folder by using the %TEMP% environment variable. If this variable is not set
for some reason then this will still default to the current directory, as it does now.
This allows batch files to be run from directories which are read only.

Since these files are not used by our (Linux) cluster there will be no differences. I
have tested a number of the scripts, but not all of them. The ones I have tested seem
to work well.

I finally found a reference which states that the %~d batch parameter was introduced
to Windows in NT4, this means that these batch files will likely fail on older versions
of Windows (ie Windows 3.x/95/98). I don't believe we need to support such antiquated
Operating Systems any further.

Fix : temporary memory device not finalized.

clist_init_data creates a temporary memory device in order to "get the memory planarity
set up", using a local variable to hold the device. When the function exits the
variable goes out of scope and disappears.

Because the memory device is a forwarding device it increments the reference count of
its target, but because it is never finalized it does not decrement the reference count
when it is destroyed, leading to an incorrect target reference count.

This only affects pdfwrite at present, but it prevents valid PDF files being written
because the file is only terminated when the pdfwrite device reference count reaches
0 and the pdfwrite device is closed.

Added calls to finalize the device before discarding it.

No expected differences.

Fix (pdfwrite) : Named destinations with no /Page not working properly

Bug #691344 "REGRESSION: ps2pdf of 8.70 generates correct hyperlinks but not ps2pdf of
8.71"

The revisions 9779 and 9788 fixed a problem where DOCVIEW pdfmarks without a /Page or
/View entry were producing invalid PDF files, and a problem with DEST pdfmarks arising
from it.

Because DOCVIEW and DEST pdfmarks share some common code in pdfwrite to create a 
Destination annotation in the outptu PDF, this still left some confusion in the code.
The problem was that DOCVIEW pdfmarks need not contain Page or View data, but named 
destinations *must*, but pdfmarks need not specify, in which case the current page is
used.

Added a parameter to pdf_make_dest which allows us to differentiate the two cases and
use the current page number for a named destination if no page is supplied.

The regression suite can't test this non-printing feature, so no differences are 
expected.

Enhancement (pdfwrite) : Fall back to Flate instead of JPEG when an image turns out
short.

Bug #691435 "any PDFSETTINGS besides /default gives dictfull error"

There are two problems; firstly when an error is encountered closing a filter the
error code (-1 or -2 usually) is returned and interpreted as a regular GS error,
resulting in ridiculous error messages. Modified to return ioerror instead.

Secondly, when an image terminates with insufficient data and pdfwrite is creating a
DCT encoded image, we can't complete the image. In this case try to fall back to the
simple Flate compressed stream instead.

gx_device_has_color() was changed 8 years ago in the deviceN commit (r2925),
from just color_info.numcomponents > 1 to 
|| (dev)->color_info.gray_index == GX_CINFO_COMP_NO_INDEX .

This has some unfortunate side-effect for continuous tone gray devices which
doesn't support transparency, such as a 8-bit gray X11 display, which goes
down the wrong code path. These are quite rare so it took 7 years for the bug 
(bug 690428) to be seen.

The ad hoc gstate setup for patterns should not call grestore after

"wraparound", creating another gstate (no saved gstate exists when the

extra gstate.  No expected differences.

Provide more robust behaviour when FT fails to render a glyph. Inistead of silently continuing when FT errors on a glyph, we'll now attempt to use the notdef, if the notdef triggers an error, we signal the error to the GS world. This ensures that any time we expect processing to continue there is valid glyph information available to the cache and other downstream devices.

This causes one regression difference with 34_all.PS, where an extra TTF notdef is rendered.

This patch adds limited support for TrueType collection fonts to pdfwrite and ps2write.

In the PostScript world TTC fonts are never passed down to pdfwrite, we only ever see
TrueType fonts. XPS, however, can pass back TrueType collection SNFTS data. This patch
uses the first font from the TrueType collection and writes that to the output file.
This may be too limited and may require further work in future.

2010-06-23T05:02:13.734047Z Michael Vrhel

Fix for 691359. Problem tracked down by Alex.  

What lcms is trying to do is to figure out the best prelinearization for the incoming data prior to doing the CLUT interpolation.  In the case when the input is RGB based and the output Gray, lcms was using uninitialized data in constructing is prelinearization.

Tangentially related, there could still be problems with what lcms is doing here if the number of Input channels is 1 and the number of Output channels is 3.  In that case, it is possible (but not likely) that I could have radically different gamma behavior in each of the RGB channels.  Trans in such a case would be constructed based upon only one curve based on the red channel.   In the real world, this is probably not a problem but ideally it would be optimal to use something that provides the best prelinearization in all three channels.  That is an optimization for Marti to do and perhaps is already in lcms2.

Erase patterns with the color white instead of filling the pattern
bitmap with 0 or 255.  

Previously the initialization was only used when anti aliasing was
enabled, now initial erasing is done for all colored patterns,
eliminating a long standing UMR in the pcl code where the pattern was
combined with the destination/source with indeterminate results.  The
UMR manifested in frequent regression reports in the pcl tests
(c321.bin for example), these reports should go away with this change,
though (NB) the change only masks the underlying issue.

Fix (pdfwrite) : limit composite object sizes when producing PDF/A

Bug #691370 "Dictionary size not limited for PDF/A-1"

The PDF/A specification insists that the implementation limitations of Acrobat as
defined in PDF 1.4 should be followed when producing PDF/A files. Accordingly this
limits the size of dictionaries to 4095 and arrays to 8191 when producing PDF/A output.

Since there is no way to ignore the problem, setting the PDFACompatibiltyPolicy to 1
'don't emit the object, carry on producing PDF/A' can't be made to work. Since the 
user has expressed a desire for an output file, we fall back to Policy 0 'Produce a
regular PDF file' instead.

Also extend PDFACompatibilityPolicy to include policy 2 'abort'.

No test file for this case, no differences expected.

Fix (pdfwrite) : Don't emit invalid PDF/A files

Bug #691383 "pdfwrite emits invalid PDF/A when glyphs are missing in the input font."

If the input file references glyphs which are not in the font, then we could emit a
PDF/A file which also referenced glyph which were not present in the fonts embedded
in the PDF file.

This patch uses the PDFACompatibilityPolicy to control the action in this case, and
avoid emitting invalid PDF/A files.

Also extended the functionality of the PDFACompatibilityPolicy to allow the user to 
abort PDF file production when a valid PDF/A file cannot be produced.

No expected differences as PDF/A production is not tested by regression code.

In the event of a FreeType error when scaling a font face, don't clean up the FT data, but leave it to the garbage collector
to call the font object's "finalize" function, which will then clean up the FT data.

Secondly, add code to deal with very low resolutions underflowing some of FT's fixed point code (similar to code for small
scale factors).

Fix pdfwrite - device reference counting problem with patterns and XPS

When using XPS as the input PDL, and pdfwrite as the output device, the pdfwrite device
was counted up by pattern accumulator allocation, but the clist accumulator never
counted the device down, leading to a reference count > 1 at EOJ. This meant that
the pdfwrite device wasn't closed, since pdfwrite only emits the PDF file when it is
closed this led to invalid unfinished PDF files.

The code here modifies the behaviour of the pattern management so that we don't use the 
'clist' path for accumulating patterns *if* the device can accumulate patterns itself
*and* the PDL doesn't have_pattern_streams (to avoid pathological PDF file problems)

This resolves the issue with device reference counts and all the FTS XPS files now
produce complete PDF files.

Fix for Bug 691368.  

lcms appears not to check its handles of link transforms when a profile is released, to clear out xform->InputProfile.  Probably due to the fact that lcms may not expect a change of the formatters after the link is created.  That would imply that we would need to create links based upon data types, which is not so efficient.  Disable this check in lcms since it is only related to named color profiles, which we will not run into.  Will kick this up to Marti.

Fix pdfwrite, faulty matrix transformations for Shading dictionaries

Bug #691352 "cairo pdf mis-distilled"

Patterns in PDF are unpleasantly complicated by the need to transform the pattern to
the 'default co-ordinate space'. Normally this means that we undo the resolution scaling
which is normally applied to the CTM.

For page streams this works well, but for forms the 'default co-ordinate space' is 
the space of the parent. For one level of form there is therefore no difference between
the page and the form. When forms are nested however, the lower form's space becomes
that of the parent. This means that patterns inside forms, which are nested inside
another form, need to be transformed to the parent form co-ordinate space, not the
page space.

Since we don't currently emit forms from pdfwrite for anything except transparency
groups what this means in practice is that we don't undo the CTM transformation if 
we are rendering a pattern inside a form, nested inside at least one other form.

Merge of icc_work branch into trunk.

These changes make the color architecture of the graphics library ICC-based.  All colors are now managed in terms of ICC profiles including PS CIE color spaces, for which equivalent ICC profiles are created.    A big feature of this change is that it makes it very easy to interface a color management module (CMM) to ghostscript.   The default CMM is now littleCMS and the interface to littleCMS is contained in gsicc_littlecms.c .

New member variables were added to the imager state including an ICC manager, which stores the default ICC profiles; a link cache, which reduces the cost of creating links between ICC profiles, and a profile cache which stores color spaces created from PS CIE, PDF CalRGB and PDF CalGray colors spaces.

A new directory named iccprofiles has been added.  It contains the default ICC profiles used if none are specified in the command line.  If COMPILE_INITS=1, these will be included in the ROM file system.  The new command line options related to ICC profiles are described in the Use.htm documentation.

For c-list based rendering, all ICC profiles used in the rendering are stored in the c-list.   During multi-threaded c-list reading, a link cache is associated with the primary reader device and is shared amongst the various threads.

Efficiency improvements were made in the handling of soft mask groups, shading smoothness calculations, and color image rendering.  

For details on the branch, please see the commits that were made within the branch.  There remain indeterminisms to fix.  The files affected include Bug688807.pdf,  Bug688845.eps, Bug690208.pdf, 09-34.PS, CATX0988.pdf,  CATX1028.pdf,  CATX1101.pdf,  CATX5529.pdf.

Rendering issues to investigate include Bug689830.pdf, fts43xx.xps (page 3) (shopping cart image), Bug689880.pdf, Bug691002.pdf, Bug689968.pdf, Bug688584.ps (page 4), catx4949.pdf.
  
Note that the number of differences generated with the merge amounts to pretty much every file.

Following Acrobat implementation but contrary to TTF spec, consider cmap entry
that has endCode < startCode as an entry with endCode == startCode.
According to the spec, "to use these arrays, it is necessary to search for the
first endCode that is greater than or equal to the character code to be
mapped. If the corresponding startCode is less than or equal to the character
code ...". I.e. an entry with endCode < startCode should have no effect.

Fix: device reference counting problem with patterns and clipping

Bug #690572 more details here. The problem was caused by installing a clip device while
drawing a pattern tile. This patch initialises the finalize member of the structure
where the clip device will be created to NULL. If a clip device is required, the member
will be initialised to a real routine. After drawing the pattern cell, if the finalize
routine is non-NULL we execute it.

This correctly dereferences the forwarded device if we create a clipping device.

Some work towards (but not a complete cure for) bug 691030.

Previously XXX_slant_into_trapezoids would check for 2 'simple' cases,
and bale into the fully general fill_slant_adjust function otherwise.
The simple cases were where the top span was a subset of the bottom one, or
vice versa.

Unfortunately the way the code to test for these cases was originally written,
one of these special cases could be used for shaped with vertical sides, and
the other couldn't.

By rewriting the test slightly, both cases can be used with trapezoids that
have one vertical side.

For good measure we also extract the 'rectangle' case out separately.

Cluster testing shows no differences (barring a couple of indeterminisms).

This reduces the output from 5 shapes (2 rectangles, 3 traps) to 3 (2
rectangles, 1 trap). One of the rectangles is still a repeat, but it's
a step in the right direction.

Fix - type 1/CFF font interpreter.
The gs_type1_piece_codes routine interprets a type 1 or CFF glyph program to determine
whether the glyph is composed of two subglyphs (a SEAC).

There was a problem with the CFF opcode cntrmask which did not cater for the case where
it is called with a number of operands on the stack. In this case the operands are to
be interpreted as vstem hints. Because this was not done, the interpreter had the wrong
number of hints, and so did not interpret enough of the following bytes as mask data for
the cntrmask operation. This led to attempting to interpret data as operands, which 
caused corrupted glyphs as well as potential crashes.

This does not appear to be tested by any of our current test files (according to a 
cluster test), so no differences are expected.

Fixes portability issue properly with r11256 (which is identical with r11520),
first discovered by Ralph 6 months ago with r10520 
which results in its being reverted in r10540 .

******************************
    Revert c10520 which causes problems with the MSVC build.
    
    $(CC_) enforces 'ansi' C under msvc32.mak, disabling any Microsoft
    extensions. This often causes problems with 3rd party libraries
    which try to take advantage of those extensions.
    
    This means that the -fPIC flag is again not propagated in the GCC
    build; this is just to unbreak the build until I can test a different
    solution which works on both platforms.
******************************
As Ralph explained then, some of libtiff requires non-ansi extensions to work.

The main culpit is tif_win32.c (which includes <windows.h>) and some of the 
file IO flags not being defined. So this commit fix the ansi issue properly.

fix windows build breakage in r11249

This change (defining TIFFCONFIG_SUFFIX) should have been part of 
   r11249 (create tif_config.h for non-autoconf build) 
which in turn should have been part of 
   r11241 (hook up libtiff with non-autoconf build via 
      "make -f base/unix-gcc.mak" and "make -f base/unixansi.mak")

The explanation is that in r10317 where Lars originally hooked up libtiff,
tif_config.h is generated by libtiff/configure (which is driven by the 
top-level configure), but special provision is provided for non-autoconf build 
(win32 and VMS) by copying from a canned header file.
If one chooses to bypass the top-level configure, *on every platform* 
(win32, VMS, and non-autoconf unix build), one must provide similiar special 
provision as well.

Personally I'll prefer not to support non-autoconf unix build.

Add skeleton support for the Bitstream font engine. In its current form this only allows
for type 1 PostScritp fonts, CFF is trivial to add, as should be support for Bitstream's
own compressed format. Addition of type 42/TrueType fonts should be patterned after
FreeType, as there is support in Bitstream for a callback to provide TrueType
outlines. There is no such provision for PostScript fonts.

To build; define BITSTREAM_BRIDGE=1 and BITSTREAM_ROOT="", the root should point one
level above the 'core' directory. In the current code this would be :
"/bitstream/FontFusion 4.5a SDK"

The final part of trying to "ln -s base/unix-gcc.mak Makefile ; make so" work.

There were some fundamental problems with the older version: The so target really
should be built in three distinct stages with three different FLAGS - the 
utils (genarch, gechogs) executable part, the shared library part, and the two final
executable part. The library should be built with the shared-object flags, but neither
of the utils nor the final executables should be built with "-shared", since they are
executables and not libraries. Hope this is clear.

There is also a little problem from SOC_LOADER not being defined if this file
is not used from ./configure's Makefile.

Fix FAPI interface
There is code in the FAPI interface for replacing a font's /FontBBox entry, this
sometimes has to create a new array to insert into the dictionary, if the old array is
not suitable for storing real values.

The code to do this continued using ref_assign_old, as it had done for replacing the
values in an existing array. This appears to be incorrect, when created the refs in a 
new array are uninitialised so attempting to use ref_assign_old tries to use
uninitialised data. 

Modified to use ref_assign_new instead, as indicated by the comments in store.h

This *may* reduce some of the non-deterministic behaviour, possibly with files such
as ShadowText.eps

Fix (FAPI)
The PDF interpreter, when a font is missing, and it has the 'small caps' flag set,
creates a substitute by altering the CharStrings of the substitute font, replacing
the lower case glyph CharStrings with procedures which 'show' the upper case glyph at a
reduced size.

This ends up in the FAPI code as a t_mixedarray type which was being missed by the check
for a t_array, added previously to handle arbitrary procedures in a type 1 font. After
extending the check to include t_mixedarray it was clear that the SEAC processing was
also messing up the dictionary lookup, so it was necessary to restore a value which
had been overwritten in case a SEAC turned up.

zero-length-font.pdf should now work as it does without FAPI, no other differences
expected.

Fix (FreeType) : illegal use of setcurrentpoint not handled as per Adobe.
Bug #691172, file type1-ce1_setcurrentpoint.ps

The PostScript file includes a font which illegally uses setcurrentpoint to establish an
absolute x/y position. The spec is quite clear that this operator is *only* meaningful
when processing the results of an OtherSubr, so this usage is definitely illegal.

Not only does it use setcurrentpoint but, unlike previous uses we have seen, it does not
simply establish 0,0 as the initial point, which can be safely ignored, it actually
uses it to displace the outline vertically.

FreeType normally just puts two uninitialised variables on the stack, ignores the
setcurrentpoint and pops the two dummy values. Instead, we now push the current x and
y co-ordinates when we get a '0 callothersubr'. In setcurrentpoint we then use the
top two values on the stack to set the current point. This now works for the illegal
usage seen here, the previous illegal usage, and does not break well-formed fonts
which actually use the OtherSubrs to set the point.

Fix (FAPI & FreeType)

Bug #691284 "Error: /unknownerror in --.FAPIBuildChar"
The issue is caused because the PostScript file adds to an existing type 1 font a 
CharString entry which is not in type 1 CharString format. I would have thought this
to be illegal but other PostScript interpreters (specifically Distiller) are happy
with it.

Modifed the FAPI interface so that after retrieving a type 1, non-CID, CharString we
test to see if it is a procedure, if it is, then we return an error from the FAPI
code to the caller (in this case the FreeType interface).

Modified the FreeType interface so that if the CharString retrieval returns an error
we return a  specific (otherwise unused) error to the caller, in this case the
FreeType engine. On return from FreeType to the interface we test for the specific
FreeType error (FT_ERR_Invalid_File_Format) and if this is detected then instead of
returning an error to FAPI, we add one to the character index (to ensure it isn't 0)
and return that to FAPI.

Finally, in the FAPI code, after 'rendering' the glyph, if we were returned a value
> 0 then we assume that 'something went wrong' with the CharString. As a last-ditch
effort we use the return value -1 to retrieve the CharString, and then 'exec' it.

NB if we fail to retrieve the CharString at this level, we return an invalidfont error.

More work towards bug 691207 (global variable removal).

There are 4 places is xps where we do eprintfs that access mem_err_print.
This resolves 1, the other 3 should never be called in files we support.

Resolve 4 const warnings from jasper.

Remove 2 calls to gs_lib_ctx_get_non_gc_memory_t from the cups driver. This
means the only places left calling this are devices in gs\contrib.

Convert calls to errprint_nomem to calls to errprint (in gdevx.c, gxttb.c,
gdevupd.c)

The only places using mem_err_print are therefore:

 * calls to debug printing functions
 * devices in gs/contrib calling gs_lib_gtx_get_non_gc_memory, errprint_nomem,
   and eprintf.
 * jasper calling eprintf.
 * gdevsco.c (but that seems intrinsically single threaded to me as only one
   thing can be using the console at a time, presumably)
 * signal handlers in os2 and iwatc for catching numeric exceptions.
 * Various devices in gs/base still call errprintf_nomem - some in DEBUG only
   code, but some not.
 * The gs_throw_imp function.

I think this may be as good as we can get at this point.

As part of the work for bug 691207 (remove global variables) we introduce
a new set of macros, "emprintfX". These do the same as the "eprintfX"
macros, except they take an explicit memory reference rather than using
the mem_err_print global.

The plan is to move everything possible over to using emprintf, leaving
callers of eprintf as 'unsafe' in multithreaded builds.

This review changes all callers of eprintf in ghostscript except:
gdevsco.c, gp_iwatc.c, gp_macio.c, gp_mswin.c, gp_os2.c, gp_os2pr.c,
gp_unifs.c, gp_vms.c, gsfid.c, contrib\*, jasper\*.

1 instance in gzspotan.c remains unchanged, but it should never be used.

As part of the efforts towards bug 691207 (global variables must be removed)
this commit reduces the reliance on mem_err_print.

Currently all calls to errwrite and errflush get the stdin/out/err details
from a global mem_err_print. For multithreaded gs this will result in output
going to the wrong place if any of them are redirected. This review splits
errwrite into 2 variants, errwrite and errwrite_nomem. The first takes an
explicit mem pointer. The second continues to assume a global one.

The plan is to make everything possible use the first. Currently debugging
calls and some 'stubborn' devices continue to call errwrite_nomem.

Local cluster testing shows no differences.

Fix (pdfwrite) incorrect ToUnicode CMap.
Bug #691274 "Missing or incorrect ToUnicode when using Identity ordering"

pdfwrite emits ToUnicode CMaps in PDF files which always use 2 bytes for the key
length. That is 0x21 is represented as <0021>, since these are hex strings there should
in fact be no difference between <21> and <0021>. It is clear from the ToUnicode
Mapping file tutorial that this is correct for mapping files.

However, a PDF file is not a CMap file. It appears that Acrobat does not like
beginbfrange data which is padded with zeros (it seems happy with codespacerange and 
destination codes which are 0 padded though).

This patch outputs ToUnicode CMaps which are not padded with 0, ie 0x21 is emitted as
<0021>, for the srcCodeLo and SrcCodeHi parameters in a beginbfrange operation. The
destination codes remain zero-padded.

Technically this would be incorrect for a real CMap file, but we don't write those
out so this should not be an issue. The change is limited to ToUnicode CMaps and does
not affect any other kind of CMap.

I believe the change will affect the data emitted for the beginbfrange,
beginbfchar, begincidchar, beginnotdefchar, beginnotdefrange and begincidrange
operators. It does *not* affect the begincodespacerange operator; although Acrobat
Distiller writes this without zero padding tests show that Acrobat is happy reading
zero-padded code space ranges.

ToUnicode information is not used in rendering PDF files, so regression testing should
show no differences. Local testing of a limited number of files doesn't reveal any
problems, but this change has not been well tested.

Modify the 'C' defaults of the pdfwrite device

Bug #691259 "HPGL graphic followed by raster graphic results in incorrect pdf"
The pdfwrite device is initialised in 'C', and then partly overridden by PostScript
initialisation. The problem is that non-PostScript input does not (cannot) execute the
PostScript initialisation, and so the defaults are left as those done in 'C'.

Not only do these defaults not match the documented defaults in ps2pdf.htm, they are
not particularly well selected. In this case the problem was caused by sending image
data at 150 dpi, but only a single scan line at a time. The default setting for
pdfwrite was to downsample image data to 72 dpi, this caused us to subsample (the 
default downsampling) by a factor of more than 2, which led to our single scan line
becoming less than half a scan line, and so disappearing altogether.

This patch addresses this issue by altering a number of the defaults to more sensible 
values. In particular we disable downsampling and enable image compression for gray
and colour images. This has the fortunate result of making most PDF output files 
smaller than before, even though we are now storing more image data.

move them inline into i_ctx_t and amend the gc routines for that
structure. Thanks to Alex for his help with this.

Fix for Bug 691014.  Problem was caused by the fact that we had a soft mask present and a pattern with no transparency.  This means the PDF14 device is installed and more importantly that transparency state pushes and pops occur to keep the softmask in sync with the graphic state.  This particular files pattern is installed as a clist, which happens to not have any transparency.  The transparency state pushes and pops were getting placed into the pattern clist when the Q and q operations occurred in the pattern, which was causing problems since the pattern clist device had no pdf14 device installed to handle such commands.  

The solution is to check, when a transparency compositor action is to occur, if the current device is a pattern accumulator or a pattern-clist device.  If it is, then the pattern instance is checked to see if it has transparency.  If it does not, then the transparency state chance is ignored.  This all occurs on the clist writing phase in the gs_trans functions.  

In addition, a fix was made so that the pdf14custom device sets up it's color information correctly.  For subtractive devices that do not have cmyk process colorants the custompdf14 device is installed.  This pdf14 device was obtaining its color_info from the target device.  The pdf14 device must be continuous tone even if the target device is not. 

Ran a regression test and saw no differences.

base/gdevpdf.c: Make the fact we're ignoring the return value of fread
explicit by casting to void.

base/gdevsj48.c: Remove unused var.

base/gdevtknk.c: Avoid gcc warning by not needlessly assigning within
expression.

base/gdevimgn.c: Fix type declaration, make function static.

base/gxdcolor.c: Remove unused var.

base/gdevwts.c: Comment out unused function, cast unused return value from
fread to void, remove unused vars.

base/gdevo182.c: Be more explicit in type definition to stop warning.

base/gdevlp8k.c: Remove unused var.

base/gdevpdfu.c: Cast unused return value from fread to void.

base/gdevlbp8.c: Cast unused return value from fread to void.

base/gdevokii.c: Explicit cast to int to shut up stupid compiler.

base/gdevpdtd.c: Add const to arg to avoid warning.

base/gserror.h: Do some macro magic to ensure that the macro always evaluates
it's arg strictly once, insists on being followed by a semicolon, and behaves
well with surrounding if/else structures etc.

Fix for a problem in the rinkj driver for Epson Stylus Photo 2200.
The code was accessing indexes 4,5,6 in plane_offsets[6] and hence was
running off the end of the array. This was causing a warning at compile time
but never caused a segv as it was merely corrupting the next entry in the
structure which was reset to 0 shortly afterwards.

Presumably the offset for one of the planes would be wrong though causing
a loss of quality.

Remove several occurrences of calls to gs_lib_ctx_get_non_gc_memory_t().
The only code that now needs this is gp_macpoll.c and gp_mspol.c for when
CHECK_INTERRUPTS is defined. This reduces the need for mem_err_print.

The only other code that uses mem_err_print is errflush() and errwrite().
Potentially these could be nobbled for a multithreaded build.

The changes here rely on the memory pointers being set up correctly. While
local cluster testing gives this a clean bill of health, it's possible that
problems will appear with files in the wider world - we'll just have to fix
these as they are reported.

Move CPSI_mode from being a global to living in the libctx, as part of the
efforts for bug 691207 (remove global variables).

I originally tried moving CPSI_mode into the imager state, which would have
been slightly nicer, but had to abandon this due to problems interacting
with the command list code. My first thought to make this work was to
push the value of CPSI_mode into the clist at initial clist creation time.
As the setting of CPSI_mode isn't vectored through the device, we can't
detect changes in its setting, but then changing CPSI_mode during the
lifespan of a clist would give unpredictable results anyway in many cases.

Sadly this was doomed to failure as if a page device is started up that
uses the clist code to do banding, then the command list is created before
CPSI_mode is enabled, and we'd operate with the incorrect value.

Moving CPSI_mode into libctx means we keep exactly the same behaviour as
we have now. This has required various functions throughout the code to
pass a gs_memory_t * around.

Localcluster testing reveals no problems.

A fix for a regression introduced by r11074 (bug 690094).

Made oog_encode in tif_luv.c reentrant by precalculating oog_tables.

oog_tables was calculated on-demand when writing TIFF files in LogLuv Encoding.

We move invalid_file_stream to be a non-gc chunk allocated to be in
i_ctx_t, and invalid_file_entry can then be replaced by
i_ctx_p->invalid_file_stream. The only tricky bits are a) the need to ensure
that i_ctx_p is available everywhere where it is needed, and b) making sure
that invalid_file_stream doesn't move when i_ctx_p is relocated.

Fix for bug 691244, reported/patch supplied by Norbert Janssen. In
revision 11045, I'd moved some globals into the libctx, which is
accessed via the gs_memory_t pointer. This has required certain
functions to now take a gs_memory_t pointer as an extra arg. In
this particular case the gs_memory_t pointer in question could be
NULL. The fix is to use one obtained from gs_lib_ctx_get_non_gc_memory_t,
a call to which happens conveniently to be on the previous line.

gs_lib_ctx_get_non_gs_memory_t is going to be painful to remove later on,
but at least this fix gets us up and running again now.

Update the clist band list compressor code to work without using global
variables as part of the workd for bug 691207 (remove global variables).

The old code used to call a function to read an initialise global structure,
then based on that allocate storage and copy the structure into it. The new
code essentially does 2 calls; one that serves to get the size, and another
that serves to initialise the newly allocated structure.

To facilitate testing, this introduces a new TEST_BAND_LIST_COMPRESSION
define. If built with this as a define, the code sets the compression
threshold to 1K, thus forcing the use of compression. A local cluster
push with this in reveals just one problem, and that seems to be in the
existing code whereby inflateEnd can be incorectly called on a NULL derived
pointer. A fix for that is included too.

No expected differences.

Fix FreeType FAPI
No bug for this (probably should be). Noticed while testing that using a TrueType to
replace a missing CIDFont (ie entry in cidfmap) was rendering the wrong glyphs, and
applying a vertical advance.

The incorrect glyph seems to be because we were incorrectly stating that the character
index was not a glyph ID, which it is in this case.

The second problem was more difficult. FreeType manufactures vertical advance metrics
for all TrueType glyphs, we override those in the incremental interface callback, but
when the TT is a CIDFont on disk, we don't use the incremental interface and so have
no opportunity to override the metric.

Addressed this by checking in load_glyph to see if the current font is not type 1 
(ie its TT), *is* a CIDFont, and is not a vertical font (WMode is 0). In this case
we simply override the vertical advance and maek it 0.

Fix FreeType
A prior update which re-initialised a glyph index to prevent old Metrics override
values persisting after a glyph was discarded did not check the ft_inc_int member of

Remove the commented out invocations of autoheader and aclocal/automake
in the autotools bootstrap script.

The various autotools modules must be invoked in a specific order, and
usually with non-default options. We only use autoconf in our build,
not any of the other tools which layer on top of it, but I had left
their invocations in the script, but commented out, so make it easier
to add them at a later date.

It's been some years since autogen.sh was added, and we still have no
plans to adopt automake. Also, the script didn't include support for
libtoolize (which is glibtoolize of MacOS X)  nor for detecting the
appropriate automake version, so it seems simpler to just remove the
commented out lines to avoid confusion.

Remove the function scope static variables from gdevcdj.c as part of the

ESC/P driver.

There are 4 variables in play here. real_rows doesn't actually need to be
static at all as it is always set before being used. The other 3 (ln_idx,
vskip1 and vskip2) all go into the 'ep_globals' structure.

There is a subtle change in behaviour here; previously these variables were
initialised to zero on execution start (and again on every flush). Now they
are initialised to zero at the start of every page (and again on every flush).
This means that leftover vskips are no longer carried forwards from page to
page. This seems like a good thing to me.

used to also be static const. This should remove them from the global variable
list in bug 691207.

Remove global variables in gdevcdj.c as part of the effort for bug 691207.

The ESC/P based printing code in gdevcdj.c uses various global variables; we
gather them into a struct here, and pass the struct between the 2 functions
concerned.

This device isn't used in the default build, so no point in testing with the
localcluster. Enabling it locally and doing before/after tests shows that
identical results are given for rendering tiger.eps.

A side effect of this commit is to remove the nasty shadowing of the img_rows
variable (doubly nasty because of it's use within a macro). This meant that I
had the code wrong for a while, so I know the test is actually testing the
right thing.

Remove global variable lbp8_end from gdevlbp8.c - it was permanently NULL
so removing it isn't hard, or risky. This will help towards the "No global
variables" goal (bug 691207).

No expected differences.

Fix for bug 691228, problems with wide strokes with round caps/joins with
antialiasing enabled.

2 small problems in the same code. In the antialiased case, we stroke by
forming 2 paths (one up either side of the line) and then reverse one and
concatenate it. This should happen whenever we meet a closepath, but due to
a misplaced return, was being missed out in some round join cases.

Also, when using a round join in the case where 2 lines meet 'in-line' we
would inadvertently leave the point on the wrong side of the line.

No changes in localcluster testing as this only affects antialiased results
and that's not tested currently.

Another attempt to fix Bug 691115. This corrects the clipping of a trapezoid
to a rectangle within the shading code. My previous attempt had failed to
allow for one case.

This causes 116 non-pdfwrite diffs, and 23 pdfwrite ones, all checked using
bmpcmp and found to be acceptable.

Fix FAPI and FreeType interface.
The Metrics override was broken, the code to retrieve the /Metrics entries (1 to 4
values) stored the results in an array in a different order to the code which read the
values back.

In addition the FreeType code did not reset the 'glyph_metrics_index' if a glyph had no
metrics override, which could lead to us using the metrics overrides from a prior glyph
if we had already encountered one using an override.

Fix FreeType
When using bitmaps from a TrueType/Type42 font FreeType uses a heuristic approach to
synthesize vertical metrics for the glyphs, including a horizontal advance. As in the 
past, this works well as long as the client knows whether the advance direction is
horizontal or vertical and uses the correct advance.

However we don't know that, so we don't want the vertical advance.

Its easiest jut to have FreeType ignore embedded bitmaps and use the outlines, in which
case we don't get the invented vertical advance. Not only that but the rendered bitmap
is a better match for the cases where we don't have a pre-built bitmap, so consistency
is improved with this patch as well.

Fix FreeType
The test file objlune_font2_mine.ps contains a Type 1 font which has a technically
 invalid glyph. The glyph executes a 'lineto' class operation before a 'moveto' class
operation.

Although illegal it seems that all other PostScript RIPs ignore this requirement, this 
patch removes the error check in FreeType to conform with other interpreters.

'Fix' FAPI with FreeType.

FreeType's hinting is worse than useless for type 1 fonts, its actually harmful. It
distorts the glyph shape because it hints an unscaled outline. While it would be best
to fix FreeType's hinting this is a large project. For now this patch disables FreeType
hinting when handling type 1 fonts.

This resolves many spacing issues as well as fixing the stroke/fill mismatch with 
ia3z3519.pdf and the incorrectly scaled outline in womanface.pdf.

In the gs_2_colors branch I had made 2 copies of the color state and swapped
between them. I had included dev_ht as part of this 'split' state, which
was a significant contributor to the slowdown due to it forcing repeated
writing of the halftone data to the clist. Also, it required significant
extra work on every setscreen or setcolorscreen operation.

Discussions with Henry/Ray/Kens et al lead to the realisation this wasn't
required. This patch therefore backs out the dev_ht split, and the changes
to zsetscreen and zsetcolorscreen. Additional code is however required to
clear the 'alternative' dev_color when a halftone is installed to stop the
'swapped out' color pointing to an illegal halftone cache.

This runs through local testing with no diffs showing (though some
strangeness was observed with an earlier version of this patch in
regression testing - Marcos has captured this with bug 691223).

This seems to have helped with the largest slowdowns, but there are still
significant differences in some cases. Very preliminary investigations seem
to show more time being spent in the interpreter/gc mechanism. Continuing
to investigate.

Fix for bug 691115.

In some circumstances, the shading code can get all the way to the point of
marking the screen/page without ever clipping to the relavent region. This
produces cases where we "draw outside the lines". Often this is masked by
the fact that we only ever draw as far out of the lines as would be covered
by an area of constant color (typically a small area).

The fix for this is to spot the unclipped case when we come to render
trapezoids to the screen, and to clip the trapezoid into (at most) 3
smaller trapezoids.

This causes 104 non-pdfwrite differences, and 24 pdfwrite ones. Examination
using localcuster bmpcmp shows them all to be acceptable.

Compute AES cypher tables at compile time instead of run time.

The aes implementation needs some tables of data to perform its
calculations. In a thread-safety review, Henry spotted that the
tables were global variables with no mutex isolation.

I believe this is actually ok. There is a static flag marking whether
the tables are initialized. If they are not, a call to aes_setkey_*
will invoke aes_gen_tables to initialize them, then set the flag.
However, aes_gen_tables operates deterministically, always writing
the same data sequence to the globals. So while there is a race
where two threads could be executing aes_gen_tables at the same time,
or while another thread is accessing the same tables, there is no
read-modify-write step which could create inconsistent data.

Nevertheless, the tables are small relative to our application, and
there is a compile time option XYSSL_AES_ROM_TABLES which generates
the data at compile time and stores it static const. This commit
turns on that option, allowing the compiler to put the data in a
non-writable segment and making the careful thread safety analysis
above unnecessary.

There should be no difference in behaviour, and Henry has verified
that the two code paths result in identical table data.

Update the list of face substitutions in .substitutefaces to include all the fonts we
define in Fontmap.GS (if not already defined).

Bug #691180, if we have a font defined in the Fontmap then we don't use the additional 
information in a PDF file FontDescriptor. Instead we stick with whatever font the PS
substitution comes up with (if the font is not present). If a member of the family is
not defined we do use the FontDescriptor. This can lead to different choices for the
substitute font. By defining the font in the substitutefaces array we can attempt to get
a consistent result.

This *will* lead to differences in the regression suite as we are now substituting 
different fonts for some missing faces. Apparently only with the test file for this
bug though.

Change the condition under which we update the overprint device when restoring
a graphics state to be more relaxed; rather than updating if the overprint
state has changed we now update if it was enabled, or it if it is enabled.

The logic behind this is that it will still fire in all the same conditions
it did before, but will also fire when we restore from a state that had it
enabled to another state that had it enabled. This should be entirely
harmless, but will allow the state to be updated in the case where a
colorspace has been updated.

This causes 2 differences in the tests, that only show up in psd files.
All indications seem to be that these files really are identical. But if
they aren't, I believe they should be progressions, rather than regressions.

This moves the trunk more into line with the output of the gs_2_colors branch.

Fixes on CUPS Raster output device:
- Fixed memory reallocation on bitmap size change. Reallocation is not only
  needed when dimendions and margins change, but also when the color depth
  changes. Fixes bugs #691029 and #691108.
- Fixed arrayoption() macro in cups_put_params() function. Array values did
  not get actually set in cups.header data structure. Bug only showed via
  a compiler warning.
- Silenced compiler warning by presetting c0..c3 in cups_map_cmyk() to zero.

Ongoing bug fixes for #690448.
The FreeType code will synthesize vertical metrics for TrueType (Type 42) fonts which do
not contain a vmtx table. This includes the vertical advance, which will be returned
to the FAPI code, and used even if there were originally no vertical metrics and the
font should not have any vertical advance.

Modified the metrics override callback, called by FT, so that if the font is a TT font,
and this is a vertical metrics call, we set the advance to 0. This prevents the
synthesized metrics from incorrectly advancing the glyph vertically.

This may eventually be a problem if we find a CIDFont with Type42 outlines which relies
on the vmtx table in the font rather than the Metrics2 or CDevProc overrides to position
the glyphs. Since this facility was only added in CPSI 3011 it is unlikely we will ever
encounter such a font. THis has not been done at present, as the information (WMode=1)
is not currently available to the code called from FreeType to override the metrics, 
and would need to be added.

Also, fixed an issue where the 'advance_v' member of the metrics structure was left
uninitialised if a horizontal override took place. This could cause glyphs to be
mis-positioned vertically.

Fix FreeType
Ongoing fixes for bug #690448. In this case FreeType generates vertical metrics for
TrueType (in our case Type 42) fonts which lack vhea/vmtx tables, which is generally
the case.

These metrics are useful to a 'normal' TrueType consumer which has a notion of the
orientation of the writing direction. However in PostScript we don;t know that, so we
apply both the horizontal and vertical advance widths.

If the vertical advance should be 0 (because its not specified) then creating one causes
the glyphs to be misplaced.

This code adds a new load flag to FreeType 'FT_LOAD_NO_SYNTHETIC_METRICS', and sets
this flag in the FAPI FreeType interface code, which prevents FreeType from manufacturing a bogus vertical advance.

2010-03-01T17:44:40.662743Z Ralph Giles

Add support to the autoconf and msvc builds to compile in a copy of
the FreeType2 library from local source.

Previously, the FAPI bridge for freetype required that the library
be compiled externally and include and link flags passed through
the FT_CFLAGS and FT_LIBS makefile variables. We now include a copy
of the freetype source in the tree, to make it easier to find a
compatible version of the source and to simplify building for
platforms that don't provide a system freetype.

Now, to enable both freetype and the FAPI bridge, pass --enable-freetype
to the configure script. This will set FT_BRIDGE=1 and the other required
variables. The configure script will prefer local source in gs/freetype2
to the copy in gs/freetype to simplify testing against upstream.

To enable freetype in the msvc build, pass FT_BRIDGE=1 on the nmake command
line.

Note that the fallback is now FT_BRIDGE=0, not FT_BRIDGE undefined; this
will require changes in any custom top-level makefiles.

Fixes bug #691147 customer 861, the optimization to strength reduce
the raster operation here is wrong, it is premised on the assumption
the colors are opaque.  If either texture or source is transparent the
strength reduction which effectively ignores the source or pattern is
wrong and it will subsequently cause opaque painting.  We've simply
removed the optimization instead of conditionalizing on opaque cases,
because tests indicate the reduction not that significant.  The
example in the bug report was reduced from a file in the XL ATS 305
test suite.  The following customer reported bugs in that test suite
are fixed by this change:

Fix, ignore a class of broken TrueType font.
Bug #691121 "gs stops in interpreting tt instructions". The font executes an MDRP
instruction with point number 28, the glyph only contains 28 points numbered 0 to 27 so

This was caused by decode_escape assuming that octal sequences are terminated by 
non-numeric characters which is clearly wrong. The octal escape decoding loop is now

1) 3 numeric characters are read from the string
2) No more data is available in the string
3) A non-numeric character is encountered in the string.

Fix colour processing. It was possible for nested ICCBased colour spaces (ie an ICCBased
space whose Alternate is another ICCBased space) to cause segmentation faults.

This was due to the fact that the conversion to base colour continuation procedure 
'currentbasecolor_cont' was supposed to scan the space from the initial declaration
each time round a loop. However a reassignment of an array pointer caused it to
rescan from the last processed colour array instead.

Normally this does not cause problems, but in the case of nested ICCBased it caused
us to generate an error.

Fixed by re-initialising the array pointer at the start of the loop.

Fix (pdfwrite) bug #691104 "pdfwrite emits garbage in the XMP metadata when DOCINFO
pdfmarks contain UTF-16BE text strings"

There were several problems. Firstly the undoing of PostScript string escapes was wrong,
Octal escapes consumed too many characters, and several escape sequences weren't
recognised.

Secondly the XMP emission didn't expect to receive UTF-16BE strings and didn't convert
them to UTF-8 for inclusion in the metadata.

This patch fixes the broken octal escapes, adds teh unprocessed escapes and checks the
DOCINFo strings before sending to XMP. If they include the UTF-16BE Byte Order Mark
then convert the strings to UTF-8.
