(In reply to comment #0) > The customer reports "they look like as they were 'colorized' and are > not rendered with a photographical style.", Further examination of the files shows that when GhostXPS generates a monochrome raster there is posterization occurring. See test_4.png attached generated with: xpshead -sDEVICE=pngmono -o test_%d.png -r300 ./fts_43xx.xps I verified that this is from an issue in the interpolation of 16 bit images in gxiscale.c 16bit interpolated images from PDF files have a similar issue. I will take care of this one. Fixed with http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=77e2fb25375f50389bfe6942507a0a513fa83ee9. This results in a few progressions in the XPS FTS test files. |
