* Bug 703404: XPS to pdfwrite patternsMichael Vrhel2021-02-171-0/+4
| | | | | | | | | | | | | | | | Patterns that are filled with glyphs and then subsequently filled with another pattern (Visual brush in XPS) was not working when going to pdfwrite due to the fact that gs_text_begin gets called by the XPS interpreter before we have finished the pattern fill of the glyph. This ends up referencing the pattern that is not done which ends badly for high level patterns. Instead if we are already in a high level pattern, set the color to just a gray. Then after the gs_text_begin, the XPS interpreter sets the brush to the visual brush which is subsequently collected. Fixing this, has revealed another XPS to PDF bug where we are not doing shading fills of glyphs correctly (at least when dealing with patterns).

* Squashed commit of the opacity_shape branchMichael Vrhel2020-03-271-1/+1
| | | | | | | | | | | | | | | | | This commit removes shape.alpha and opacity.alpha from the graphic state. This involved removal of methods in the postscript based PDF interpreter, changes in the pdf14 device, changes in pdfwrite, the XPS interpreter, and the PS transparency test file that is present in examples and on the cluster. The goal of this commit was to avoid confusion and conflicts between shape.alpha opacity.alpha and the stroke and fill alpha values (CA ca). This change resulted in progressions in the XPS file. There were changes in a couple PDF files that required some investigation. In particular, the change in the dashed lines of Bug694981.pdf. Robin and I looked at this. Robin determined it was due to differences in stroke_add and stroke_fill not giving identical results. In the end, the new output looks closer the what AR provides.

* Squash warnings: XPS MSVCRobin Watts2016-01-041-3/+3
| | | | | | | | Add some casts etc to squash (most of) the warnings seen in an MSVC debug build of ghostxps. We have an unavoidable "cast away of const" in a devspecop call, and various stupidities in the jpegxr lib left over.

| | | | | | | The gxps had numerous places where allocation failures were ignored, writing to RAM at offsets from 0 (NULL). This no longer fails, but the fixes are not yet complete. Running a memento build with the parameters: MEMENTO_SQUEEZEAT=1 gxps -o /dev/null -sDEVICE=ppmraw in.xps

* xps interpreter - correct high level pattern handlingKen Sharp2013-10-111-4/+6
| | | | | | | | | | A silly error was causing fills to be applied twice. For opaque fills this is merely a performance penalty but for transparent fills the result is incorrect. Thanks to Phil McSharry for identifying the problem and supplying a solution. This shows progressions in a number of test files.

* Introduce GS_THREADSAFE define and modify printing calls.Robin Watts2012-09-181-14/+14
| | | | | | | | | | | | | | | | | | | | Lots of debugging/error information is printed using eprintf and dlprintf etc. These functions do not take a gs_memory_t * and are not safe for use within code that runs under multiple instances created by gsapi. Introduce new versions (dmprintf, dmlprintf etc) that DO take a gs_memory_ *, and move as much of ghostscript/ghostpdl's usage over to these as possible. I have not touched the contrib directory, and some locations in the code do not easily have a gs_memory_t to hand, so I have left them be. If the GS_THREADSAFE define is made during building, then the functions that don't take an explicit memory handle are #defined away to nothing. If the GS_THREADSAFE define is made, we disable the gsapi check that checks for a single init.

* Fix in XPS interpreter to ensures we only push the smallest transparency ↵Michael Vrhel2012-07-051-17/+56
| | | | | | | | | | group needed + more For a path that included an opacity mask, the XPS interpreter was pushing a soft mask that included the entire page (it actually just looked at the current clip path). This fix incorporates the path that we are filling in the computation of the transparency group size. Also, there were issues with the softmasks in general that were causing them to be double applied. Fixes 693042 and also provides improvements for 690951. Also this should fix 693137 and 692892
* Update copyright "headers".Chris Liddell2012-06-131-6/+9
| | | | | | | | | | | | | | | | | | As agreed on IRC and via e-mail: Reinstate the reference to the LICENSE file. Remove copyright references to Aladdin Enterprises and artofcode (some references remain in comments about historical copyright assignments, and the like), in favour of Artifex copyright notices. Update copyright dates. Remove the $Id$ "tag". Since the move to git, the $Id$ "tag" comment in each file is redundant. No cluster differences.
* XPS Whitespace handling fixRobin Watts2012-01-261-9/+5
| | | | | | | | | | | | | Update the xps point reading code to use strtod rather than atof; this returns us an updated string pointer, rather than relying on us second-guessing where it may end up. Change xps_get_point to return this updated pointer, and change some calls of this to avoid having to skip whitespace (and potentially getting it wrong) after the call. Spotted as part of the commit to take the latest XPS changes into MuPDF.

* Fix for Bug 692510 white space XPS interpreter fixMichael Vrhel2011-10-191-11/+47
| | | | | | XPS interpreter was not very robust in its handling of white space in many locations. I created a general function to handle this in place of the many uses of sscanf in the interpreter.

* Enhancement to XPS interpreter - add high level pattern supportKen Sharp2010-06-211-4/+10
| | | | | | | | | | | | | | High level devices (pdfwrite basically) prefer to receive patterns as high level, rather than pattern tiles as this is more compact. This patch checks the device capabilities and if it can support high level patterns we emit those rather than tiles. This is done by returning gs_error_Remap_Color from the 'remap' procedure and then controlling the device's pattern accumulator. Many files work better (converting to PDF) with this approach, though there are still some problems. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@11409 a1074d23-0009-0410-80fe-cf8c14f379e6

| | | | | | | | | | | code (when executing strokepath or ustrokepath postscript operators). This means we better match acrobat. This frees us to optimise the non CPSI_mode version so as to produce simpler stroked paths with the same outlines. This should allow us to be faster in the non strokepath cases. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@10291 a1074d23-0009-0410-80fe-cf8c14f379e6
* Implement a random file access mode for the XPS parser that uses less memory.Tor Andersson2009-10-291-0/+2
| | | | | | | | | | | To enable this mode, set the XPS_ZIP_SEEK environment variable which will cause the interpreter to spool the data to a temp file and then run the parser in the new mode. This is going to change in a later patch to plmain that will enable the interpreters to directly access the job files. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@10243 a1074d23-0009-0410-80fe-cf8c14f379e6
