2012-03-15Fix for bug 692865. Make XPS interpreter use ICC color spaces for defaultMichael Vrhel1-0/+1
The XPS interpreter was still using Device color spaces for its default color spaces. This fix has it use ICC color spaces by default which is required by the spec. This revealed an issue with the color space handling of the opacity masks. These were getting drawn in sRGB color space but the transparency group is linear gray. Since we are drawing the opacity mask as a luminosity mask that is gray we ended up mapping through a nonlinearity.
2012-03-15XPS Whitespace handling fixRobin Watts1-1/+1
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.
2012-03-15Fix for Bug 692510 white space XPS interpreter fixMichael Vrhel1-0/+2
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.

Create individual colorspace objects for each profile, and cache them in the colorspace hashtable in the context. Remove the colorspace type enum for images and use a gs_color_space object instead. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@11428 a1074d23-0009-0410-80fe-cf8c14f379e6

2010-06-21Enhancement to XPS interpreter - add high level pattern supportKen Sharp1-0/+1
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

2010-06-04Change so that we avoid double decoding of images in xps code. Previously ↵Michael Vrhel1-0/+3
we were doing a full decode into buffers to see if an alpha channel was present in the image data. Now we just check the header. Patch checked by Tor. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@11354 a1074d23-0009-0410-80fe-cf8c14f379e6

gsicc_manage.c/h to fall in line with the name space of the other files that came from the icc branch. Currently working on the documentation and it is clear that this is needed (and I wish I had done it earlier). git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@11346 a1074d23-0009-0410-80fe-cf8c14f379e6
2010-04-26Add support for parsing unzipped XPS files.Tor Andersson1-3/+1

2010-04-26Simplify ZIP parsing.Tor Andersson1-125/+74
The special mode of the XPS interpreter that parses the ZIP file incrementally as a stream has proven to be useless. None of the files we see in the wild make use of the features that are required for a streaming XPS parser to behave well. As a result, this mode was always buffering up data and using lots of memory. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@11130 a1074d23-0009-0410-80fe-cf8c14f379e6

2009-10-29Implement a random file access mode for the XPS parser that uses less memory.Tor Andersson1-28/+65
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
2009-10-23Correct remaining prototype warnings in the ghostxps code.Ralph Giles1-0/+5
xps_debug_item, xps_debug_path, and xps_debug_resource_dictionary are added to ghostxps.h as public functions. xps_parse_content_relations, xps_process_compatibility and xps_debug_item_imp are made static since they are intended to be used from inside the same file. xps_debug_item_imp gets a prototype even though it is static because it calls itself recursively, and this triggers the gcc -Wmissing-prototypes warning. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@10218 a1074d23-0009-0410-80fe-cf8c14f379e6

2009-10-15Don't disable dprintf() and friends in non-debug builds.Ralph Giles1-8/+0
This reverts a patch from Ray (r2812 in the old ghostpcl repository) which was a quick hack to silence the extensive tracing output ghostxps produced at the time. Now most of those calls have been moved to xps_debug_foo() functions which aren't called in normal builds and a few warnings which shouldn't particularly be silenced. The patch worked by just defining the dpf macro to the empty string, but that creates 'operand of comma operator has no effect' warnings on gcc 4.4 when the remaining arguments tuple is interpreted as a discarded expression. git-svn-id: http://svn.ghostscript.com/ghostscript/trunk@10170 a1074d23-0009-0410-80fe-cf8c14f379e6
