Fix (pdfwrite) bug #691101 (part 2 of 2)
The revisions 10474 and 10476 were intended to address an indeterminism but actually
introduced a fairly serious regression. The code was changed to return any error value
from the glyph_info method before testing the members of the 'info' structure passed to
the method. Previously one of the member could be examined when an error had meant that
the member was still uniinitialised.
However, these revision missed the fact that the glyph_info method can return a
'rangecheck' error when they require a CDevProc to be executed. Because the error code
was tested before checking for a CDevProc, the pdfwrite code never executed the
CDevproc.
This resulted in a (very) few regressions, this is because the PDF interpreter uses
a CDevProc to alter the widths of glyphs if a /W array is present in a PDF file.
The code now initialises the member of the structure to 0, which we then test before
checking the return code. If we need to run a CDevProc we now do so.
Part 2 of this commit explains some further issues with CDevProcs.

<pre>
Fix (pdfwrite) bug #691101 (part 1 of 2)
The revision 10603 fixed a number of issues relating to FontMatrix and descendant fonts
of CIDFonts. However part of the fix, in CIDWProc, used 'currentfont' to address the
font dictionary instead of 'currentdict', as is done in the rest of the routine.
For rendering devices this works well, but for pdfwrite the two dictionaries are not
the same, and this causes PostScript errors.
This error was initially hidden by the revisions 10474 and 10476 which inadvertently
caused all CDevProc routines not to execute when using pdfwrite.
This patch alters the CIDWProc to use currentdict instead of currentfont, there are no
differences with rendering devices but with pdfwrite this causes the CDevProc to
execute properly, eliminating a number of errors (when the faulty revisiions 10474
and 10476 are rolled back)

<blockquote>
<pre>
Fix (FAPI)
Bit complex here. The FAPI code needs to tell the font rendering engine how much to
scale the font in order to get properly sized bitmaps. It does this by looking at the
FontMatrix, comparing it with the 'original' FontMatrix and determining the scale from
there.
The problem is that the 'original' FontMatrix was being retrieved from a copy of the
font stored when it is defined, intended for use by pdfwrite. When we define a font we
check to see if it has an /OrigFont entry, and simply use the one which is present if
we do.
This causes us problems if we make a new scaled font by taking an existing font and
changing its FontMatrix. We don't write the new FontMatrix into the OrigFont dict, and
so when we come to determine the font scale we divide the FontMatrix by the 'original'
stored matrix. This effectively results in any scale factor built into the FotnMatrix
being applied twice, once by FreeType because the FontMatrix isn't the default, and
once by the FAPI when it divides the FotnMatrix by the original.
I didn't want to modify the OrigFont entry, as that would probably break pdfwrite, so
I've modified the FAPI code to take a copy of the FontMatrix at the time the font is
defined and store it in its own structure. We then use this to determine how much to
scale the font by dividing the current FontMatrix by the matrix at the time the font
was defined.
This fixes my hand-crafter test file and improves the output of Bug687615.ps and
two_encodings.ps. The output is now the correct size, but the spacing is wrong in
bug687615.ps and many glyphs are missing from two_encodings.ps.

Fix (pswrite)
The pswrite device only partially implemented the 'file per page' output model. It
closed the output file and the bbox device, but did not open a new output file or
reopen the bbox device, leading to potential crashes later when the pswrite device
tried to access the bbox device.
This patch reopens the bbox device, and opens a new output file, at the end of every
page when we are outputting one file per page. The problem is that this will emit an
empty EPS after the last page is completed. Fixing this would mean delaying opening the
output file until we had received a marking operation. That's more work than we want
to do on this device, so this is being left as an issue.

This commit is a fix for bug 691021 which had quantized (unsmooth) shading artifacts when transparency was present.
The primary changes to the code are:
The adaptive (non-fixed) smoothness method is now used in the shading code when transparency is present. Previously there was a check put in place and if there was transparency a fixed amount of smoothing was enforced.
The color cache used in the shading code was updated to use the color information in the transparency device that is contained in the imager state. This object is initialized with either the target device when there is no transparency or with the PDF14 device when there is transparency. In this way, the proper color information is used by the cache.
The shading code makes use of the member variables comp_shift and comp_bits in the color_info member variable of the target device. This information is now properly updated in the PDF14 device as the transparency group color space changes.
A clist change was also required for proper XPS rendering of gradients. When it has a gradient with a transparency component, the XPS code first creates a soft mask group and draws the alpha shading. It then creates a transparency group to draw the color components portion of the shading. When the transparency group is popped, is is composed using the soft mask buffer which is the XPS opacity shading. When we are going through the clist writer, the writer will end up drawing the shadings for both the opacity component and the color component with trapezoid fills. Later, during the clist reading and execution of the trapezoid filling, a clipping device is created. This device is created with the color info properties of the target device, which in our case is a PDF14 device. The clipping device is first created during the soft mask group. This group has color information associated with a grey device since it is just a single channel (the XPS alpha channel). Later, the same clipping device is used when we are doing the trapezoid filling during the transparency group fills. The problem is that the color information of the target device may have changed, for example if the transparency color group is RGB or CMYK. We need to test for that and update the color info for the clipping device.

Attempt to fix bug 691030, regression with thin lines. This regression was
caused by revision 10391, where I pulled the rectangle special cases into
line with the more general case. Sadly, the more general case appears to be
wrong in the way it rounds lines lying on integer values.
The fix is to correct the rounding in the general case, and to keep the
rectangle special cases in line with this. Unfortunately this produces
unacceptable results with the PCL interpreter.
We therefore commit a compromise solution, whereby we make the code do the
'correct' thing (or what we believe the correct thing is) for postscript,
and leave operation alone for the other languages. We spot this by examining
the fill_adjust values. This seems to works, with the minor problem that we
still see some changes in PCL due to it sometimes using non-zero fill_adjust
to thicken lines. A visual check shows the diffs to be reasonable.
Expected Differences: MANY. But extensively checked with htmldiff and they
seem OK.

Fix (FAPI - FreeType). The current FAPI implementation for FreeType ignores any vertical
advance defined in a glyph. This causes type 1 glyphs defined with an sbw (not hsbw)

advance the current point correctly.
There is a separate issue with FreeType which does not return the correct vertical
advance which will be addressed in a separate patch.
This patch adds the vertical advance to the metrics structure and uses it as a

<pre>
Fix (FAPI). The code to 'serialise' a CFF font (that is to convert the internal GS
representation back to a stream resembling a disk font) was seriously broken when writing
a local Subrs DICT.
The offset to the Subrs DICT is stored in the Private DICT as an offset from the
start of the Private DICT. This means it depends on the length of the Private DICT,
but the Private DICT includes that offset, so the length of the Private DICT is
dependent on the size of the offset (CFF integers use between 1 & 5 bytes depending
on their value).
The normal method for dealing with this is a process of refinement; assume that a 1 byte
representation will suffice, calculate the size of the DICT, see if that size can be
represented in 1 byte. If not assume a 2 byte representation, recalculate the size
of the DICT, see if it can be represented in 2 bytes and so on.
It looks like the code was intended to do this, but it was in fact seriously broken
and ended up incrementing an integer for size of DICT until it became negative, and
then stored a negative (and incorrect) offset to the Subrs.
Replaced the code with a simple for loop surrounding a switch.

Previously we would embed a CIDToGIDMap for a CIDFontType 2 font (TrueType outlines) if

However the spec (PDF 1.7, Section 5.6, "Glyph Selection in CIDFonts') says that we

not.
This patch modified the CIDToGIDMap production so that we ignore the production of PDF/A

then we create a CIDToGIDMap, if it is not, then we don't.

Update the example file. The old file used a single 'charpath pathbbox' to determine the
height of the text. It then used the 'scale' operator to draw larger text.
If the path was fixed to pixel boundaries, and the point size was low (default 15
points) this could lead to a small error which was magnified by the cumulative scale
operations.
This led to significant differences when using the FreeType font code, as it seems to
return a hinted path which is bounded by pixel co-ordinates, unlike the regular GS
code.
The altered code scales the font and recalculates the height of the text each time
giving more accurate results. In addition a minimum size has been introduced (50 points)
for the calculation of the text height. Together these result in much closer output.

Fix bug #691043 "Vulnerability report : Ghostscript gs_type2_interpret null ptr
dereference (Segmentation Fault)". The problem appears to be caused by a corrupt
compressed data stream which results in garbage font data being sent to the type 2 and
under some conditions the type 1, font interpreters.
As noted these font interpreters are normally coded to be intolerant of faults, and
do not normally perform much error checking. As a result badly formed (or as in this
case, garbage) fonts can cause serious problems.
Although the null dereference is the cause of the error, this is actually caused by
interpreting the data as a font, and decrementing the font instruction pointer below
the bottom of the instruction stack.
The patch here adopts the suggestion from the original bug reporter of checking the
pointer before the dereference, but in addition adds some checking when the
instruction pointer is decremented to see that it does not descend past the bottom of
the stack. This is because tests showed that it was possible to reach this point with
a non-NULL pointer, which was still invalid and caused a segmentation violation.
In addition the free_glyph routine has been modified to check the pgd (pointer to
glyph data) parameter is non-NULL, and that its 'procs' member is non-NULL, before
attempting to call the free procedure. This fault was exposed by selecting the pdfwrite
device.
Although improved this is not a comprehensive fix, there are other locations where the
font instruction pointer may be incremented past the top, or decremented past the
bottom, of the instruction stack. However the FreeType font interpreter correctly
detects the problems without causing a crash, so I don't think we should expend too
much effort on rewriting our current font code to cope.

FreeType interface fix. When using the incremental interface to FreeType (which in fact
we always use), Ghostscript is responsible for locating and passing the glyph
description data to FreeType, and so we don't bother to track certain kinds of data
in the FreeType structure.
However, even when using the incremental interface, FT still tests some of this data, in
particular it tests the requested glyph index against the reported number of glyphs
in the font, and aborts if the index is too large.
This patch simply sets the num_glyphs member of the FT_face structure to a large number
(65534) so that the internal FreeType test is successful, and we don't have to bother
with the record-keeping that would be required to keep this member updated when fonts
change.

fonts with symbolic flag set or having no encoding entry.
The flag -dIgnoreTTEncoding is removed because symbolic fonts always do this
now and non-symbolic fonts should never ignore encoding.
Bug 691035, customer 220.
The new spec includes cmap 3,0 in the supported list. We discovered this
before but didn't use cmap 3,0 as a first choice. PDF 1.7 is not clear about
the choice between symbolic and non-symbolic branches. Current algorithm
is based on a few experiments with AR 8.
The patch causes rendering differences in comparefiles/keyboard.pdf
A few undefined characters change from boxes to empty space.
Current rendering of undefined characters in Ghostscript doesn't match
Adobe Acrobat and should be revised.

A specific test is used to ensure that zero width/height clips are handled

Update the arguments passed to ghostscript by htmldiff.pl so that they
more closely match those used by the localcluster.
DETAILS
localcluster uses "-dNOOUTERSAVE -dJOBSERVER -c false 0 startjob pop -f"
The use of -dJOBSERVER changes the output given for some of the ps3cet files
due to having different stack contents at the outer level.
This seems to eliminate most of the differences between htmldiff results
and local cluster results. Those that remain seem to be caused by differences
in the output of devices (htmldiff uses bmp, wheras the localcluster uses
pgm/pbm/etc).
One minor point; the use of -dJOBSERVER is defined in doc/Use.htm
to require input to be supplied via stdin. I originally wrote the code to
do this, but it seems this gives problems on Windows for some files
(for reasons that are beyond my comprehension at this time). Accordingly,
I've swapped back to supplying the filenames on the command line and
everything seems to be fine.
If this presents a problem on platforms other than windows, simply
edit the value of $redir as shown at the top of the file and redirection
will be used. If this turns out to be necessary, it may be possible to
automate this.

The expansion was only needed if the device color space was RGB, but not 8 bit.
This doesn't really give valid output anyway for RasterOps, but at least
we no longer reference past buffer bounds (see the 'trow' calculation in
gdevmr8n.c).

Fix (FAPI) : Ignore some TrueType faults
Details
The file Bug689516.pdf contains TrueType fonts with problems, one of the fonts has
multiple fatal errors:
1) GLYF and LOCA tables contain more than NumGlyphs glyphs, and some of these
glyphs are used.
2) At least one glyph uses more points than the declared maxPoints value.
3) The FPGM is invalid.
Acrobat ignores these but elides the glyphs with problems, GS's internal TT rendering
engine issues a warning and also elides these glyphs.

different, possibly slightly more informative, warnings, and continue, ignoring the
faulty glyph(s).

Fix (FAPI) : FAPI code not expecting unsorted LOCA/GLYF tables
Details
The FAPI code needs to copy the GLYF data, to do this it needs to know how long the
data is. The only way to do this is to consult the LOCA table which gives the offset
to each glyph in the GLYF table. Subtracting the start of the glyph from the start of
the next glyph in the GLYF table gives the length.
The existing code assumed that the GLYF (and therefore LOCA) tables was ordered, that is
that glyph 1 followed glyph 0 and so on. There is no such restriction, glyphs can
appear in any order, so the simple subtraction caused incorrect glyph lengths, which
could lead to truncation of the data and caused errors.
We now pick up the offset of the glyph we want from the LOCA table, and then search the
entire table to find the glyph whose offset is nearest (but after) the offset of the
glyph we want.

Fix for bug 690218. If the SeparationOrder was specified, then we should only allocate buffer space for those colorants. See devn_put_params for details on this. Right now, the PDF14 device will always include CMYK. A future optimization is to be able to NOT have those included in the bufferallocations if we don't specify them. In that case it would then be possible to output 8 separations at a time without using compressed color. Note that if SeparationOrder is not specified, the number of colorants used in the pdf14 device buffer allocations is equal to the number of colorants in the document up to a maximum of 64.</pre>

updating begin_image and fill_mask to cope with white/black+transparent
Apparently not all black/white+transparent uses the copy_mono code path, which
has been recently updated to do white-on-mask. There are two other ways
black/white+transparent can pass through pxl - in begin_image() (as part of an
RGB/Gray image with an alpha channel) which is most of the files in bug
690947, and fill_mask() which has no known cases yet.
Note the new addition to fill_mask() and begin_image() is not identical to that
in copy_mono() in the case of the drawing color being white - fill_mask() and
begin_image() both try to draw white on the blacks of a black/white mask and
transparent on the white, whereas copy_mono() draws white on the white and draw
transparent on the opposite (set to black but really transparent), so the
source is inverted in fill_mask() and begin_image() compared to copy_mono().

Fix (FAPI) : invalid fonts resulting in errors
Details
The files Adobe Garamond CE.pdf, Bauhaus CE.pdf and Futura CE.pdf alll contain subset CFF
fonts, and use the same (ecaron) glyph. In all three cases the font uses the deprecated
'SEAC' endchar construction and in all three cases at least one component glyph is not
present in the font.
Probably the producer didn't realise the component glyphs were required amd did not
include them in the subset.
As a result the FAPI code properly rasied an error, sicne the required glyph is not
presemt. Adobe Acrobat (of course) ignores the error and simply elides the missing
glyph. Regular Ghostscript has at some time been coded to do the same and emit a
warning.
For compatibility this 'feature' has been implemented in the FAPI interface.

Fix (FAPI) : intermittent crashes with TrueType fonts
Details
The sfnts reader code in the FAPI module maintains a pointer to a string from an array
of strings (the /sfnts array). It then used the offset member to point along the string
to the current byte within it. When reading multiple bytes, it checks there is
sufficient data by checking ptr+offset against the size of the string. However the code
did not increment the offset member after reading multiple bytes, instead it incremented
the actual pointer. This completely bypassed the size checking, which could cause a
crash depending on the memory layout. This was only likely to happen with fonts with
very large TrueType tables (ie those not conforming to Type 42 recommendations
regarding string sizes, see tech note 5012)
Altered the code to always increment the offset rather than the pointer so that size
checking works properly.

Fix (FAPI) : Incorrect GID supplied to font interpreter for CIDFonts with TT outlines
Details
CIDFonts use a CID, for CIDFonts with TrueType outlines the font contains a CIDToGIDMap
entry which is used to convert the CID into a TrueType Glyph ID (GID). We were not using
the data, which resulted in us passing the CID directly to the font interpreter, which
caused the wrong glyph to be extracted, or failures to occur because the GID was larger
than the number of glyphs in the font.
The type 42 font code in GS converts the CIDToGIDMap into a CIDMap entry, we now use
this to convert the CID into a correct GID for the font interpreter to use.

The check in zputdeviceparams relied on code > 0 or the width or height change

forwarding needed to check if the target device closed (such as when DeviceN
parameters changed) and return code=1 to trigger the device reinitialization.
Also the forwarding of close_device needed to make sure and set is_open=false

Fix (pdfwrite) : problems with type 3 fonts and glyphshow
Details
Bug #690738 "pdfwriter garbles/omits glyphs"
Bug #690836 "Bug during eps to pdf conversion"
Bug #690882 "ps2pdf mangles type 3 fonts"
Revision 9804 modified pdfwrite to try and make text in type 3 bitmap fonts, derived
from PCL input, more likely to produce a PDF file with searchable text. Part of the
change was to try and group multiple glyphs together into a single string instead of
emitting them as single glyphs.
Unfortunately that was an optimisation too far. There is no way currently to tell the
difference between a type 3 font which has been converted into a bitmap, one which
started as a bitmap, and one where the CharProc has been captured (PostScript). We do
however store bitmap and outline glyphs in different fonts, the problem arose if we
converted a CharProc to a bitmap, and then stored a CharProc, the code did not realise
that we had switched fonts and tried to use the bitmap font for both.
This occurs because matplotlib defines all its fonts as type 3, applies an Encoding
to them, but never uses it, instead showing all glyphs with a glyphshow operation.
This makes it difficult for pdfwrite to assemble an output type 3 font with a valid
Encoding, and PDF doesn't support glyphshow. In this case if we find that the glyphshow
uses a glyph which is not in the font's Encoding (eg /multiply) we end up producing a
bitmapped glyph instead.
Ideally we would capture the CharProc, but doing so would be very difficult in this case
for a very minor benefit. Instead I've chosen to remove this optimisation.
Previously we would emit text something like:
x y moveto
(ABC) show
Now we do:
x y moveto
(A) show
x1 y1 moveto
(B) show
x2 y2 moveto
(C) show
There seem to be no differences in the test suite with PostScript and PDF files,
probably because no files apart from matplotlib use glyphshow in this demented fashion.
However, this does result in a large number of PCL test files exhibiting very small
differences with text, especially at low resolution, due to tiny shifts in position.

Fix for segfault reported in bug 690927 and two of the segfaults of bug 690880.
DETAILS:
The pdf14_compressed_encode_color (and _decode_) assumed that the device was
a pdf14_device and directly accessed the devn_params using that structure offset,
but when filling gradients the device was the target device (a gx_device_printer
subclass) so the pointer was wrong.
The primary change is in base/gxblend1.c and uses the device's ret_devn_params
procedure (if possible). If the proc is NULL, or if it returns NULL, then and
only then use the devn_params structure assuming that the device is a pdf14
variant (usually pdf14cmykspot or pdf14clistcmykspot).
A check for this is performed in DEBUG builds in case this expected invariant
is ever violated. In order for the check to be made simpler, the names of all
of the devices were changed to all start with "pdf14" (some were PDF14).

Fix for Bug 690531, excessive slowdown while rendering a complex stroked
path with anti-aliasing.
The problem is caused by the gs filling code grinding to a halt under the
weight of an extremely complex path produced by stroking an already complex
path and then filling it all at once.
This change can be seen as a workaround in that it does not change the
filling code at all (this may be considered in future after the freetype
changes have gone in), but instead adds a new mechanism for stroking that
produces (broadly) equivalent strokes which happen to fill more easily.

Replace only the initial definition of the gs executable
in the script wrappers.
It is possible to change the name of the compiled gs executable; this is
generally used to distinguish multiple installed versions. In r5212 a
sed command was added to the unix build scripts to rewrite the name of
the gs executable embedded in the various wrapper scripts so that they
would call the corresponding version.
This was broken in r8107 where an extra clause was added to have the
wrapper scripts prefer the gs executable in their local directory
over any in the path. Unfortunately the sed command rewrites both
attempts to set GS_EXECUTABLE.
This commit only rewrites the specific assignment of the default name.

Fix (TT font substitution) : Incorrect Widths applied to CIDFont glyphs from PDF file
Details
Bug #690876 "Spacing issues with mixed asian/roman characters"
The PDF interpreter applies the /Widths array from a PDF CIDFont by applying a custom
CDevProc to alter the width of the glyph before it is cached. This procedure relies
on the CID of the glyph being correct, as this is the index into the Widths array.
This works correctly for genuine (embedded or from disk) CIDFonts. However, if we use
a disk-based TrueType font as a substitute for a missing CIDFont, the integer which gets
passed into the CDevProc routine is the TrueType glyph ID (GID). This is because the
CID from the CIDKeyed instance must be converted into a GID for us to consult the font.
Using the GID instead of the CID results in incorrect widths being applied.
This conversion happens in PostScript and the original CID is not available at the time
CDevProc is executed.
Since this only affects substitution of fonts its arguable that the CDevProc is useless
in its original intent anyway.
This patch detects a CIDFont being replaced by a TrueType font by checking the font
type is type 11 (CIDFont with TT outlines), that the font dictionary contains a key
called /File (has been read from disk) and that the font_name and key_name strings
are different (substituted font).
In this case we ignore the CDevProc routine, and simply use the original widths from
the TrueType font. The widths won't be the same as requested by the job, but then
neither are the glyphs. For this job, because the widths of the TrueType glyphs are
sensible, the result is an improvement in the output.

Fix (TT fonts) : regression with TrueType fonts
Details:
Bug #690642 "conversion to PDF aborts after 800 pages"
Bug #690921 "Regression: /invalidaccess in --run-- starting with r9897"
The patch for #690642 was an interim fix which was known to have flaws and was supposed
to be revisited to fix them. Unfortunately a file appeared which exhibited an attempt to
put a key in a read-only dictionary before this was done.
This patch resolves both issues by removing the need for a temporary key (hence we no
longer write into a read-only dictionary) and also removes some ugliness (and slight
performance penalty) by not creating a dict from the stack, patching the dict, and
loading its contents back to the stack.

Bug fix for Bug 688604, "incorrect rendering of a returning curve".
The code currently in ghostscript checks for the bbox of a beziers control
points being of zero width/height and to avoid a division by zero just chooses
not to subdivide this curve. This is wrong in some cases.
The fix here is a cheap and cheerful one; in the case where one dimension is
zero and the other isn't, we basically do the same calculation as would be
done in the two dimensional case, but just with a one dimensional distance
as input.
This causes various diff; all look good in my tests.

Affected Devices are tiffgray, tiff12nc, tiff24nc, tiff32nc, tiffsep, tiffsep1,
tiffcrle, tiffg3, tiffg32d, tiffg4, tifflzw, and tiffpack. Also, two new
devices: tiff48nc and tiff64nc (16 bits per component rgb and cmyk respectively)
have been added.
Libtiff 3.9.2 is included in the source tree as tiff/. It is possible to link
to the system's libtiff by passing --with-system-libtiff to configure. Passing
--without-system-libtiff will force the build to use the in-source version. By
default, the newer library (based on TIFFLIB_VERSION in tiffvers.h) is used.

partly reverting r8576, and other file-size improvements.
After r10313, it becomes possible to revert r8576 (which was
a work-around to bug 688992, but increases file-sizes in some cases).
It is also found that r8576 is in fact more efficient for
small rasters; so it is only partly reverted. In two other places where
write_image_data() is called, switching to gx_default_copy_* for single-line
images/masks is likely to work well also.
This fixes bug 690857, where 12-07C.PS uses a lot of 1-bit images,
and shrinks the file size by a factor of 4.
There are a total of 4 places where write_image_data() is called
(copy_mono/copy_color/fill_masks/image_write_rows) - the 4th does
not use the data_bit field, nor is it likely to be called
with small rasters; so it is left unmodified.

caches the null/non-null state of both pen and brush in the

Fix (pdfwrite) : type 0 fonts with type 3 descendants could confuse pdfwrite by using
stringwidth
Details
Bug #690875 "Ghostscript locks up writing PDF file"
There is code in gdev_pdf_text_begin which skips caching of type 3 glyphs when using
stringwidth. This prevents glyphs becoming bitmapped and ensures that pdfwrite and
the glyph cache are coherent.
The code did not check for composite fonts using type 3 descendants. In this case if a
job used some glyphs for stringwidth, then later used at least one of those glyphs and
one glyph not previously encountered in a single string pdfwrite would enter an
endless loop.
pdfwrite would notice that a glyph was not marked as 'used' in its internal cache, and
exit pdf_text_process to run the outline for the first glyph. GS would note that the
first glyph was already cached (from the stringwidth) and move on to the next glyph.
GS would render that glyph, pdfwrite would capture it and mark that character code as
used.
On returning to pdf_text_process the first glyph should be marked as used now, but it
was not, so pdfwrite would once again exit and the loop would repeat.
Fixed by checking string using composite fonts to see if any glyph used a type 3
descendant, and disabling caching if it does.

<blockquote>
<pre>
This is the initial commit of the 'tiffsep1' device code that emits
separation files as 1-bit per pixel TIFF files, a separate file for
each separation. This is a CMYK plus Spot color device, and the
number of separations (spot colors) supported depends on the gdevdevn.h
setting of USE_COMPRESSED_ENCODING. By default this is true as long as
the sizeof(gx_color_index) is >= 8, so up to GX_DEVICE_COLOR_MAX_COMPONENTS
layers can be generated (current default 64). Without compressed color
encoding, then only 8 total (C, M, Y, K and 4 spot colors) can be
supported.
Files are named with the separation layer in ( ), e.g. x(Black).tif if
the OutputFile is 'x.tif'. Since no composite CMYK is generated, the
base file is deleted ('x.tif' in the example).
DETAILS:
This device uses a hook of the 'fill_path' device call to collect the
threshold arrays from the imager state. In case a file does not perform
a 'fill' operations, the gsdevice.c code does a dummy fill of an empty
path to allow the 'sep1_fill_path' code to convert the 'order' into
threshold arrays.s
The 'open' and 'put_params' device functions are modified to make sure
that if the clist device is being used, the 'sep1_fill_path' proc will
be re-hooked (the clist initialization overwrites some procs including
the 'fill_path' proc). The sep1_fill_path then forwards to whatever
fill_path proc was set by the gdev_prn_open or put_params.
A later commit will move the 'thresholds_from_order' function to another
common file (probably gsht1.c) and change it to generate a threshold
array of type 'gs_threshold_halftone' with NULL transfer and closure
functions. This function is in gdevtsep.c now since it is the only
device that needs it (for now) and development was easier with all
changes more or less localized (at least non-trivial ones).
The make files are modified so that the 'tiffsep1' device is included
by default (where the tiffsep device is included).
The actual halftoning is done using 32-bit writes of the dithered line
since testing showed this to be 27% faster (although more complex).
Note that the compressed color encoding (the current default) is about
half the throughput compared to direct encoding. Users that are sensitive
to performance (who isn't) and that only need 8 or less total colors
(CMYK plus 4 spot colors) will want to turn compressed color encoding
off.

Fix (pdfwrite) : Unchecked return value from pdf_write_spot_function
Details
Bug # 690796 "Invalid Halftone objects in PDF (negative object references)"
Two fixes, firstly the return value from pdf_write_spot_function() was not being
checked in pdf_write_spot_halftone. We now check the value and return an error if
required.
Secondly when unable to write a spot function because of the num_bits required we were
returning a rangecheck error. This was hidden by the failure to check the return value
noted above. The problem is that rangecheck is a special case return when called via
gdev_pdf_fill_path() and causes it to assume transparency is involved and use a
different fill method. We actually want an error so instead of returning rangecheck
we no return limitcheck instead.

<pre>
Reintegration of gs_extendgraphic branch into trunk. This fixes bug690777.pdf. The main purpose of this commit is to relay information about q and Q operations (extended graphic state push and pops) to the pdf14 compositor. The reason this is needed is that the softmask is part of the extended graphic state.
DIFFERENCES EXPECTED:
Bug688807.pdf has a minor progression. Bug688159.pdf and Bug689509.pdf also reported differences but I could not see any using cmpi. Also, we may need to take a look at the XPS output. It was unclear to me which were regressions and which were indeterministic.
DETAILS:
The following example (as well as bug690777) drove the need for this commit.
Consider a transparency group that covers an entire page and let there be a
soft mask that is set as part of a graphic state. Let there be 2 bands in
this clist and let the soft mask bounding box be such that it intersects band
1 and band 2. Currently, there will be a Push Transparency Soft Mask and an
End Transparency Soft Mask compositor action added into the clist for BOTH
bands. Now, let there be a transparency group that is drawn only into band
one. There will be a Push Transparency group and End Transparency group into
band 1. Now let there be a Q followed by a transparency group that is drawn
only in band 2. What should happen, is that the soft mask should no longer be
present due to the Q operation. Unfortunately, in the current architecture,
there is no compositor action to let band 2 know that the soft mask is not
valid to use.
Another example is a case were we set a graphic state with a softmask, which
will introduce the Push Transparency Soft Mask and an End Transparency Soft
Mask compositor actions. Follow this by a q operation. Set another graphic
state, with another softmask. This introduces another Push Transparency Soft
Mask and an End Transparency Soft Mask compositor action. During the clist
reader stage the maskbuffer for our pdf14 context will be the last soft mask
that was specified. Now on the writer side do a Q and draw. What should occur
is that the first transparency softmask should be active. Unfortunately, this
information is not communicated through the clist AND the old soft mask buffer
has been lost.
The primary issue in these examples, is that we need to detect and store in
the clist graphic state changes that occur and have an impact on our
transparency state.
To solve this problem, the following is proposed:
1) At the PDF interpreter level for the /q and /Q operators, check if the page
uses transparency. If it does, then execute a .pushextendedgstate for /q and
a .popextendedgstate for /Q.
2) Add zpushextendedgstate and zpopextendedgstate commands in the c code.
These operations will respectively execute a gs_push_transparency_state and a
gs_pop_transparency_state during the clist writer process. Deep in the
graphics library there will also be gx_push_transparency_state and
gx_pop_transparency_state. These are executed during the clist reader side.
4) Two new device procedures were added related to the transparency state.
(push_transparency_state and pop_transparency_state). These were added at
the end of the device procs for backward compatibility with older devices.
4) A change to the pdf14 ctx stack such that the maskbuffers are a
stack. In fact, they are now reference counted since they can be multiple
copies (actually pointers to the same data buffer) in the mask buffer stack.
5) A flag xstatepending was added to the graphic state to communicate when a softmask transparency
group pop had occurred. In that case, we need to keep track of the q and Q
operations. Otherwise, they are ignored early in the process to reduce the
number of compositor actions.
In addition fixes were made to the background content handling (BC) of the soft mask.
Now the softmask bounding box is the same as the parent group unless the BC value
is white which would indicate that the BC will not have any effect on areas drawn outside
the softmask group bounding box. Changes were made in the code that computes the band range for the
softmask group.

Fix for bug 690805.
If a dash pattern exactly fits into the path to be stroked, a 0 length dash
note is emitted, with (0,0) tangents. This causes an extra cap to be put on
the path when rendering, causing stray marks.
The fix is to recognise the case when we are about to emit a dash note with
no useful information in the note (i.e. if udx and udy are 0, then don't
emit the dash note). This leaves the renderer free to make it's own decision.
Examination of the bitmaps shows that all the differences are in fact
improvements. The following files are identified by the localcluster as
being differences, but no differences are found in local testing:

Fix (ps2write) : Allow use of /Indexed colour spaces in PostScript output.
Details
Although opdfread.ps has always contained code to handle /Indexed colour spaces,
ps2write has never emitted any. This is because it is always executed with a PDF
CompatabilityLevel of 1.2, and PDF 1.2 doesn't support Indexed colour spaces.
PostScript, however, does and it seems unreasonable to deny the use of these spaces
when we are emitting PostScript.
This code checks to see if we are emitting PostScript when comparing the compatibility
level to see if Indexed spaces are allowed, and permits /Indexed for PostScript.
This change did, however, expose a number of flaws in the opdfread code when handling
Indexed spaces. These are all due to the fact that an Indexed space can use an existing
space as its base, and this can lead to multiple attempts to resolve or flatten the
underlying space.
FunctionToProc is altered to check it has been passed a function dictionary to convert
and to ignore the operation if not.
SubstitutePDFColorSpace allows for CIEBasedA and CIEBasedABC spaces, which may be the
result of a prior substitution.
ResolveArrayElement checks the element to see if it is passed a procedure containing
an integer followed by a procedure, before executing the procedure. This is because a
colour space which has already been resolved may have a procedural look up and
executing that disturbs the stack.
DecodeArrays generated an incorrect Decode array for Indexed colour spaces.

Fix (pdfwrite) : The PDFACompatibilityPolicy switch was being overwritten by PDFA on
setpagedevice
Details
Bug #690803
The PDFA switch is stored in the page device dictionary, and the device member is reset
from the stored setting on each setpagedevice. This was defeating the
PDFACompatibilityPolicy setting which tried to disable PDF/A production when the input
could not be converted to a compliant PDF/A file.
Because the PostScript value is subject to save and restore, its all but impossible to
alter the PostScript saved value. So added a new device member 'AbortPDFAX' which can
only be set from C. This is set when non-compliant input is detected and prevents the
emission of (currently) PDF/A file (may add PDF/X in future). It does this by resetting
the device PDFA member every time the device parameters are set.

Fix (pdfwrite) : Improve symbolic font detection
Details
Bug #690767 "Problems with PDFA"
Revision 9944 altered the way that we detect whether a font is symbolic or not. This
involved several changes; fixing existing broken code, adding /.notdef detection and
attempting to check encoded positions of glyphs before deciding a font was non-symbolic.
The encoding position test was incorrect for TrueType fonts, however, leading to some
fonts being needlessly declared as symbolic. This patch moves the encoding test to the
font descriptor assembly, which is the correct place to test it.
While this resolves the customer issue, it is not a complete solution. A truly symbolic
TrueType font would still be written as a symbolic font and when creating PDF/A files
there are strict limitations on the form of TrueType fonts. In particular they must only
contain a single CMAP table. Because we do not completely generate TrueType fonts for
embedding, but copy some tables, we cannot meet this restriction.
This will continue to be a potential problem until the TrueType font embedding code is
rewritten properly.

Improve EOF detection with the romfs iodevice. Fixes a segfault
loading shorter resources. Patch from Alex Cherepanov, bug 690697.
Details:
Resources are loaded using the --run-- operator, which looks into
the first 1023 bytes of the file to check for PDF, etc. It calls
.peekstring which uses s->end_status to detect the end of the file,
but s_block_read_process() didn't set it, allowing repeated reading
of the same block and the file position to run off the end of the
buffer. This was the cause of the segfault.
We now use '>=' instead of '==' when checking the file position to
avoid the overrun, and raise the EOF flag when the last block of the
file is read. This can be done because the whole block is always
decompressed and copied to the stream buffer.</pre>

Details
There was a fixed limit of 64Kb on images used by Pattern colour spaces in early
versions of Acrobat (presumably using a string for storage). This limit does not apply
from Acrobat 5 onwards so the size test has been amended to also consider the version

Fix for transparency problem, caused by the alpha parameters in the ExtGState

Bug 690770 for customer #1110. Thanks to Michael Vrhel for analyzing the PDF
to find the area that the PDF interpreter was mishandling.
DETAILS:
The ExtGState is kept as values in the dictionaries on the dictstack and are
sent to the graphics library as needed using '.set***alpha' operators. The
CA and ca values were properly set to 1 in the graphics library when the Do
operator was used to execute Form or Image objects, but the corresponding
FillConstantAlpha and StrokeConstantAlpha values were not being set in the
ExtGState so any operations in a Form that set the values in the graphics
library from the ***ConstantAlpha values in the ExtGState could set them
to incorrect values.

Fix (pdfwrite) : Stricter checking when converting type 4 to type 1 masked image
Details
Bug #690704 "Regression: seg fault with pdfwrite"
pdfwrite was performing an optimisation to convert type 4 masked images, which are only
supported in PDF 1.3 and above, into type 1 masked images which are supported in all
versions.
However the test was faulty, assuming that a one bit per component image was always
suitable. If the image had multiple components the result was incorrect and when the
input was from PCL could lead to errors.

Fix (type 1 parser) : Correct logical flaw in SEAC parsing
Details
Bug #690720 "Regression: pdfwrite generates bad pdf files from PostScript files"
The Type 1 font routine to detect SEAC (Single Encoding Accented Character) glyphs and
return the component glyphs, 'gs_type1_piece_codes' made a faulty assumption that a
SEAC glyph was purely composed of two components and that any glyph with a path
construction operation could not be a SEAC.
This restriction is, unfortunately, not documented in the spec. The Genoa test file
16-10.ps includes a font with SEAC glyphs which also contain path construction
operations. The failure to properly detect the SEAC was causing pdfwrite not to emit
the component glyphs when subsetting fonts, resulting in PDF files containing invalid
fonts.
Fixing this then revealed that the reduced type 1/type 2 font interpreter used for
detecting SEAC glyphs did not properly handle a number of type 2 instructions. This
patch also adds support for hstemhm, vstemhm, hintmask and cntrmask.
Because we do not have a full featured CFF parser in C yet, it was not possible to add
full support for the callgsubr operator (global subroutines are apparently not available
to the reduced interpreter). If the relevant gsubr contained the endchar for the glyph,
then this causes the interpreter to fail as we cannot process the subr.
Since SEAC operations are deprecated in type 2 fonts, and a gsubr completion of a SEAC
is extremely unlikely, I've chosen to return when a callgsubr is encountered and treat
the glyph as not being a SEAC. This may need to be revised in future.

Fix for bug 690534.
DETAILS:
We now handle the softmask BC entry properly. This background color is to be composited with the drawings into the softmask. We now properly initialize the softmask buffer to have this compositing occur. If we are outside the softmask bounding box then the luminance of the background color is used as the softmask value. This fixes several rendering issues.

A fix for the rendering issue that occurred with bug 689581 after fixing the rangecheck error. This should fix 689581.
DETAILS:
The rendering problem is evident when rendering the simplified file in 689581. When going to a sep device, the softmask gray scale image is encoded using the compressed encoding function defined for the pdf14_CMYKspot_procs pdf14 device. The decoder for the CMYKspot device is set to cmykspot_pdf14_procs. Unfortunately, when the color procs are set for the softmask decode (based upon the softmask CMYK color space) the decoder was set to cmyk_pdf14_procs which resulted in an improper decode of the color values for the softmask. The fix is to detect the presence of the separation case and make sure that the decoding procs are assigned appropriately.
DIFFERENCES EXPECTED:
None in the normal regression tests. There could be some differences with sep devices when processing softmasks.</pre>

Pass the full CFLAGS to CCAUX in the autoconf build, instead of just
GCFLAGS. This propagates target-defining options which are typically
set in XCFLAGS to build utilities so that, for example, -m32 results
in the correct sizes in arch.h.
Note that this may complicate cross-compiles. In theory CCAUX has
separate, simpler flags because of this, but there are also several
examples in the documentation of using XCFLAGS this way, so this
seems to the the safer approach at this time.
The dynamic flags for the separate x11 devices module are also
passed through XCFLAGS but they do not harm other than cluttering

Fix (pdfwrite) : Write ToUnicode CMaps with 2-byte code space ranges and keys
Details
Bug #690722 "Problem with the font embedding logic"
The existing ToUnicode CMap code wrote a ToUnicode CMap the same as a regular CMap, so
the code space ranges and keys could be arbitrary lengths depending on the number
of codes and their values. This appeared to be correct per the PDF Reference and the
CMap specification.
However, buried in technical note 5411, the 'ToUnicode Mapping File Tutorial' is a
single reference:
"the following “codespacerange” definition, without exception, shall always be
used: 1 begincodespacerange <0000> <FFFF>endcodespacerange"
This means that ToUnicode CMaps must be treated specially to ensure that they always
have 2 byte code space ranges and keys.
Modified the single allocation of ToUnicode CMaps so that it always specifies a 2
byte range.

Adjust ht cache allocation to a size that will actually be used by the
cache logic. The changes allow for replicating tiles along the width axis
up to a ulong multiple that optimizes tile blitting in the mem device
logic. Addresses bug 690693 by reducing the memory used from > 1Gb to
< 200 Mb. As noted in the comments to that bug, there still may be some
optimizations remaining.
DETAILS:
Reduces the allocation from over 1Gb for Special Test C1 of 09-40.PS to less
than 200Mb by reducing the ht cache size to what will actually be used. The
code in gxht.c initializes the cache limits the 'rep_count' to 8*sizeof(ulong)
so any more than that per tile (1+width*height) will not be used.
Debug code in gxht.c (gx_ht_init_cache) to check:
if ( rep_count != (8 * sizeof(ulong)) )
dprintf("non_optimal ht cache size\n");
never detected a different value, so the ht cache size should be optimal
with this patch -- neither too much nor too little allowed for the most
efficient width repetition. This was tested at a variety of resolutions from
72 to 1600 with several files that defined screens and also checked with
'stocht.ps' that the maximum ht cache size was chosen to fit. Also the cluster
regression shows no differences (I'd have been surprised if it did).
Note that the above test is _not_ part of the patch since it was only used for
evaluation.
Also see rev 8526.

Since the eexec operator specifies that one never reads more than 256 bytes

Fix (pdfwrite): Writing invalid numbers for linecap and linejoin parameters
Details:
bug #690691: "setlinecap"
pdfwrite was emitting the linecap and linejoin values directly from the graphics
state to the output PDF file. However the GS graphics state also supports the
additional PCL linecap and linejoin values, which are not supported in PDF. This
resulted in PDF files with illegal values.
Modified the code to replace tringle linecaps with round linecaps, triangle line
joins with miter joins and none joins with bevel joins. These are not correct but
are reasonable solutions for now. We should degenerate 'none' joins into a
sequence of discrete paths.
Also added future protection by converting unknown values of linecap into butt
line caps and unknown values of linejoin into miter line joins. In both cases
a debug warning is emitted.

Fix (pdfwrite) : Embedded TrueType fonts not correctly flagged as Symbolic
Details
Bug #690688 "-dSubsetFonts=false produces incorrect PDF file"
The method Acrobat uses to select glyphs from TrueType fonts is arcane and dependent
on the setting of the Symbolic/non-symbolic flags. When we subset a font the encoding
is always created incompatible with StandardEncoding, and so we mark the font as
Symbolic.
However, if we embed the entire font, we try to decide if its symbolic or not. To do
this we check the names of all the used glyphs to see if they are in StandardEncoding
and if they all are we start by assuming the font is *not* symbolic (there are other
checks).
However, there were a number of problems with this check. Firstly the reverse encoding
which is used to do the work does not contain the .notdef glyph, which *should* have
meant that all fonts were incorrectly marked as symbolic. The only reason it didn't
is because the return value from the routine gs_c_decode was checked against
gs_no_glyph to see if it failed to match. But gs_c_decode actually returns GS_NO_CHAR
in this case.
So the test was incorrect, and never correctly detected that a glyph was not in
StandardEncoding.
The test is also insufficient, in addition to being present in the font, the glyph must
also be encoded at the correct position in StandardEncoding, the font in this job
contains glyphs whose names are all in StandardEncoding, but they are not encoded at the
normal positions, so the font *should* be marked symbolic.
This patch skips the test for the .notdef glyph, correctly checks the return value
from gs_c_decode, and adds the test against the encoding position.

Fix for bug 690670. Softmask color space was incorrectly getting set to DeviceN when the color space was undefined for the group and the output device was a separation device.
DETAILS:
For a transparency group, this method is OK as we blend the individual channels as defined in the PDF spec. For a mask, this is not OK, since we have to map to luminosity and the mapping from the process + spot colors to luminosity is not defined. Solution is to use the concrete space of the current space of the imager state for the softmask for this situation.
