Fix for issue found by Chris where we have a soft mask embedded in a softmask and graphic state pushes and pops occurring. In this case, the soft mask stack that is saved gets out of sync compared to the one in the context state. Use of the stack count can catch the issue and correct it. Also a rename of one of the variables in the pdf14 code to make it easier to debug.</pre>

<pre>
Resolve build issues with language_switch and UFST.
I had (wrongly) assumed that the PCL/language_switch builds with UFST
and COMPILE_INITS=1 would have the relevant paths correctly setup for
the PS/PDF world to access the Microtype FCOs. It turns out they are
done in an incompatible manner.
So, I've renamed the path variables (in the makefiles) so there isn't
a clash between PCL and PS/PDF, ensured that the variables are correctly
passed through recursive (n)make calls, and tidied up the FAPI options
for the language_switch build.
Not only does this allow language_switch to build with the UFST, but the
Postscript interpreter does now use FAPI/UFST to access the Microtype fonts
for the built-in fonts, and uses FAPI/Freetype for downloaded fonts.

<pre>
A temp fix for bugs 692038 and 692065. The clist devices that are created for the threads now inherit the icc profile from the target device. I need to set things up so that the device profile is no longer reference counted since we could have a race condition problem if the different threads are incrementing and decrementing the count and if the command is not atomic on a particular architecture. The plan will be to no longer ref count the device profile but to have it maintained until the the actual target device is destroyed. There will be a bit of work to do with respect to the pdf14 device, which can have a device profile that is different than the actual target device. That profile can be altered with the transparency group pushes and pops.</pre>

Fix (ps2write) : Indexed colour images have incorrect /Decode
Bug #691924 "Differences in colour with ps2write"
The problem was due to the opdfread code generating a /Decode for an Indexed colour
space where the value was [0 2^n] and should be [0 ((2^n) - 1)]. This caused the
highest image sample to be mapped to 1 past the end of the samples in the colour space.
Normally this doesn't matter, because the values are clamped to 'hival' in the Indexed
space. In this case, however, the image was 2 bpp (4 values) but the colour space was
defined as a full 256 indices, with only the first 4 being used.
The incorrect Decode caused the image sample value 3 to be looked up as colour space
sample 4, which was set to all 0 (black) causing incorrect colour values.

Fix (ps2write) : Don't set a default halftone.
Bug #691923 "Differences in dithered output with ps2write"
The PDF interpreter emits a setpagdevice between every page of output, in case the
media size has changed. The implementation of setpagedevice resets the halftone to be
the default halftone (106 lpi 45 degree line screen).
This is a problem for ps2write, and potantially pdfwrite, as there is no way to
differentiate between a default halftone set by setpagdevice, and a halftone contained
in the input file.
To avoid embedding an unhelpful halftone, we now check the device parameter
'/HighLevelDevice' in the setpagedevice implementation, and if it is present and true,
we do not call .setdefaulthalftone.
Also updates documentation on device parameters.
This causes differences on every 1-bit rendering test (ie pkmraw) of the ps2write
output file, so approximately 1300 differences are to be expected.

Fix Bug 692064. Tiffscaled device was checking on page print time that the
expected size of the page wouldn't make the page too large to fit in a file.
This code was copied from the tiffgray device (as we render internally in
8bpp). As we output in monochrome however (and may use compression) the
test is in fact bogus, and should simply be removed. We do that here.
It's entirely possible that we should be removing the test from the
tiffgray device too - most systems with 32bit longs support large files these
days, and compression may apply here too anyway. I'll leave this until it
becomes an issue though.

<pre>
Some updates to the new device parameters. It turned out that the intended parameter
Type32ToUnicode was incorrectly implemented. This should actually have used the
WantsToUnicode parameter, because the code actually controls the processing of
GlyphNames2Unicode tables from Windows PostScript.
This means we no longer need the Type32ToUnicode parameter and it has been removed.
Added initial documentation of these parameters.
This appears to cause some differences in Bug690829.ps rendered at 300 dpi.
This is a surprise, because the changes should have no effect on devices other than
pdfwrite/ps2write, but the new result is better than the old, so this is a progression.

<pre>
Some (broken) TrueType fonts have out of order loca tables, which can result
in the calculated glyph data lengths being larger than the actual
available glyph data. Normally this does not cause a problem, but if the glyph
in question is in the final bytes of the stream, we encounter an unexpected
end of data condition when creating the glyph data buffer to pass into
Freetype.
So the FAPI interface code will now ignore that error, and adjust the byte
length to correctly reflect the number of bytes available in the buffer.
It is safe to do this because, in the event we have a genuine out-of-data
condition, Freetype will return an error when it tries to interpret the
glyph outline.

<blockquote>
<pre>
Planar device is broken w.r.t rops in a cmyk space - this commit fixes it.
The planar memory device sets itself to use gx_default_strip_copy_rop
rather than mem_strip_copy_rop. mem_strip_copy_rop knows that rops on
cmyk pixels should actually convert to rgb, perform the rop, and convert
back again, but doesn't know how to convert the results back when it's in
planar mode. gs_default_strip_copy_rop can cope with planar mode, but doesn't
know to convert to rgb first.
The first fix included here is to extend mem_strip_copy_rop to know how to
write back to planar format, and then to make the planar memory device use
mem_strip_copy_rop.
This then exposes various flaws in mem_strip_copy_rop, including the fact
that it relies on being able to set the offset in get_bits calls when this
is sometimes not possible. We therefore fix the code to manage offsets
by explicitly updating them.
Also, the raster used in mem_strip_copy_rop was incorrect - we use the
correct one and get much better results.
No cluster differences expected as the planar device is not tested.

Update the remaining PostScript files (mostly the PDF interpreter) to use the new device

Some more modification is still required, but we're nearly there. We will continue to
check the device names in gs_pdfwr.ps when setting up the default state for those
specific devices.
Although not strictly a Distiller device, ps2write declares itself to be 'IsDistiller'.
This is because some PostScript test files were found to behave differently if the
distillerparams operators were available, in particular files would be oriented
differently if the device was deemed to be a Distiller.

<pre>
Fix for bug 692038.
This fixes 3 issues when using a CIELAB based profile for the output device ICC profile.
One was a problem when handling separation color spaces when they had the ALL entry and we were going to an additive device. AR does a 1-INK level for the device values and no color management. We were doing the same, but this approach will not work if our destination color space is CIELAB. Now if we are headed toward CIELAB we do the 1-INK to RGB and then transform to CIELAB.
Another was that transparency blending should never be done in CIELAB or similar type color spaces. With transparency, the PDF14 device inherits the profile for the target device and if the transparency groups don't specify a color space we would end up blending in CIELAB. The solution was to detect this situation and use the defaultRGB profile for blending. Conversion to CIELAB occurs during the pdf14 put image operation.
Finally, with shading in transparency, we need to make sure to pass along the transparency device through the shading parameters whenever we have a color mismatch between the pdf14 device and the target device so that the shading will occur in the proper color space.
These changes are all related to a non-tested cluster case when we have -sOutputICCProfile=lab.icc</pre>

extra code that can be performed so as to ensure that valgrind doesn't

Unfortunately, it seems that in the portrait case, if we don't blank the

Fix for compositor device chaining in the pdf14 device. This was detected in a
file that did overprint along with transparency. The pdf14 device incremented the
ref_count for the overprint_device, but never decremented it since the 'finalize'
of the pdf14 device was left at NULL rather than being set to the gx_forward_finalize
function which should be used. The gx_device_set_target, rather than rc_assign does
the proper set of the finalize proc pointer so that reference counts for the device
chain are properly maintained. Detected by customer 532 since their device freed
the clist buf_device resulting in the overprint_device having a 'target' pointer
to freed memory, causing a SEGV when the 'finalize' function executed.
No regressions expected since in the normal code, the GC frees the devices that
were left unreferenced by the free of the pdf14 device.

Introduction of a member variable in gs_image1_t, which will let us know the original source type of the image. For example if, the parent source were type3 this spawns two type1 images. One for the mask and one for the image data. The mask is rendered using image render simple. If the image is monochrome or indexed, it is rendered with the renderer in gximono.c . If we are going to a halftone monochrome device, we end up using the fast threshold based renderer which has its interpolation stepping in device space as opposed to source space. This causes very minor differences between the mask and the image data. To avoid this, we use the old rect_fill code for the image type3 data to ensure a more exact spatial match.</pre>

<pre>
Added color management support to the CUPS ...toraster filters
Replaced the ...toraster filters by one filter executable, gstoraster,
written in C. This filter converts both PostScript and PDF input into
the CUPS Raster format using Ghostscript with the "cups" output
device, controlled by settings in the print queue's PPD file, by
command line options, and by settings embedded in a PostScript input
stream. This is now done with color management based on
printer-specific ICC profiles referenced in the PPD file or supplied
by the color management daemon colord. The CUPS PPD extensions
concerning color management
(http://www.cups.org/documentation.php/doc-1.4/spec-ppd.html) are made
use of if used and the colord daemon is used if it is present. colord
is accessed via D-Bus, but the new filter can also be compiled without
D-Bus and in this case only the CUPS PPD extensions and ICC profiles
assigned to the print queue are used for color management.
Thanks to Richard Hughes for the patch.

<pre>
Fix bug reported by "new customer feb 2011", whereby gs 8.71 on an embedded
ppc platform is getting the colours on an image in a pdf wrong.
Debugging shows that in gs_indexed_limit_and_lookup we take a floating point
value, clip it, convert it to an int and use it to lookup which colour to use.
On the reference x86 run we have a value of 1 (0x3f800000 as an IEEE float).
On the ppc we have 0.999999 (0x3f7fffff as an IEEE float). This tiny difference
results in values of 1 and 0 respectively when converted to the int, giving
the wrong colour.
The fix here is to add a small epsilon before conversion.
A quick experiment in adding 0.5 rather than epsilon shows worse results.

<pre>
Add new plib family of devices (PLanar Interlaced Buffer). These 5 devices
(plib = r8g8b8, plibg = g8, plibm = mono, plibc = c8m8y8k8, plibk = c1m1y1k1)
use a new 'band donor' interface to request a band buffer, pass back
rendered bands, and release bands at the end of the page.
The idea is that other firmware can implement this simple interface, and
Ghostscript can thus easily drive systems that expect planar interlaced
input.
On the whole there is relatively little new code here; the majority of the
work is done using the existing planar device with the odd tweak here and
there. Firstly, we lift the (artifical) constraints of the number of components
supported (so greyscale is accepted as a planar device for simplicity).
We spot the num_components = 1 case and just use the existing memory device
interface.
Secondly, we add a fast 888chunky to 888planar unpacking routine for use
with copy_color.
Within the plib device itself, we make use of the facility to set the line
indexes to allow for interlaced operation. It would be easy to extend this
device to offer planar non-interlaced operation too built on the same band
donor interface simply by omitting this code.
For debugging purposes we have options within the plib devices to store the
data returned in each band into pxm files (as appropriate to the number of
components). This code is deactivated by default as the output of this
device is via the band donor interface, not the output file.
No cluster differences expected as this code is disabled currently.
Next job: discuss with Marcos how to cluster test this.

Initial reorganisation of code towards using copy_rops for copy_mono.
Split the guts of mem_mono_strip_copy_rop out into a separate function

device space, leaving the original to cope with fiddling the rop according
to colors.
This 'inner' function is moved to gdevm1.c so it is present in both gs
and ghostpcl builds. The existing (bitrotted) code in gdevm1.c to
'USE_COPY_ROP' is revamped to call mem_strip_copy_rop_dev, but is disabled
currently as the cluster is showing a few differences that need to be
tracked down.
Also, this introduces new code to do gsroprun's using code in a generic
header file that gets repeatedly #included with different options. This
code is currently disabled until we can verify that it gives identical
results. The new 'templated' code uses native ints where possible, and
(in initial limited testing) seems to perform better than copy_mono.

Enhancement (pdfwrite) : performance improvement
Bug #691946 "Conversion to PDF becomes slower and slower"
There are many places where pdfwrite compares composite objects for equality. This can
be a very slow process, depending on the nature of the object, and becomes progressively
slower as more object are added to storage.
Previously we had added a MD5 hash to the stream data of a cos_stream in order to
improve the performance when checking fonts for equality, this change takes the whole
process much further. We now store an MD5 'fingerprint' for each composite object,
initially this is not computed and is marked as not valid.
Whenever an equality test takes place we check to see if the composite object has an MD5
hash calculated, and if it does, we compare the MD5 hashes. If it does not then we
compute an MD5 hash, store it, and mark it as valid. Note that for cos_stream types
we store *two* hashes, one for the dictionary and one for the stream data.
If we alter the contents of a composite object then we mark its MD5 hash as invalid so
that we recompute it on the next occurence. Technically there could be a problem if
a composite object contains a composite object, and the descendant object is altered
after the MD5 hash is calculated for the parent. However this should not occur given
the way these structures are used (these are pdfwrite internal structures, *not* PS or
PDF objects available to the interpreter).
This very significantly improves performance on some files, the test file for bug
#691946 takes 2642 seconds without this change (and DetectDuplicateImages true) while
it takes 963 seconds after this change.
Note that this change depends on revision 12169 and should ideally be used with
revisions 12168 to 12171 inclusive.
No other differences expected.

Fix (pdfwrite) : images being scaled incorrectly
Found while dealing with other problems. pdfwrite uses the image 'height' (rendered
height) and number of lines of data to calculate a 'scale' which it then applies to
the current Transformation Matrix in order to calculate an image matrix.
However, when an image was detected as a duplicate, the scale factor was calculated
from the first image's dimensions, and then applied to the CTM for the second matrix.
This did not appear to cause problems for PostScript and PDF but causes serious bugs
in a number of PCL files, and was clearly incorrect. We now save and restore the
height and width when substituting images to prevent this problem

enhancement (pdfwrite) : Allow duplication image detection to be disabled
pdfwrite tests every (non-inline) image against every other stored image to see if it is
a duplicate, and if so does not embed the duplicate in the output but simply references
the original.
This can be slow for files with many images (each stored image must be checked when a
new image is encountered) and may be of limited benefit.
The new flag DetectDuplicateImages (default true) can be used to enable or disable
this behaviour
No differences expected

Fix (pdfwrite) : Correction to an equality test
This fixes a long-standing bug when checking the equality of patterns.
We need to ensure when substituting patterns that neither of the patterns is already
substituted. But the code only tested one of the patterns (and was a duplicate of
another test), which led to incorrect results. This should always have been a problem
but for some reason seems to have been masked in previous releases. New code for
testing equality of composite objects revealed the problem.
No differences expected, as the problem is only revealed with code which follows in a
subsequent commit.

Fix Bug 691917. In revision 11146 I made op_array_table_global and
op_array_table_local be elements of the context rather than being
globals, and changed all the code to access these elements through
the context.
Unfortunately I forgot to cope with when new contexts are generated by
forking execution. The correct fix is, I believe to simply copy the
op_table pointers over to the new context. This has been done here, and
seems to solve the reported bug.
No cluster differences expected.

Fix : colour space handling bug and improved handling of broken ICC space
Bug #691941 "Interpretation of PDF aborts with /typecheck"
The PDF file in the specimen contains an invalid colour space of the form:
/Indexed [/ICCBased <</N 1 /Alternate [/Indexed /DeviceRGB 255 7 0 R]>>] 255 7 0 R]
The number of components in the ICCBased specification is incorrect, as the profile has
3 channels. This was not detected previously. Falling back to the /Alternate we see
that we have a /Indexed space depending on a /Indexed space which is also invalid, but
we choose to ignore this.
There was also a bug in the colour space handling for ICCbased spaces which caused a
typecheck if the alternate space was a /Indexed space.
Finally, the PDF interpreter is updated so that when given a stream as the data source
for a /Indexed space it reads and returns a string which is the greater of the declared
size of the stream, or the calculated size required, given the number of components.
Previously we always returned the calculated size, which was too little in this case
as the number of components in the ICCBased space is incorrect.
With these changes the (invalid) specimen file runs to completion.
No differences expected.
