Created attachment 10624 [details] An eps with a DeviceN using the same color-names as the artifex examples but using very different colors in the alternate colorspace. Using -sDeviceNProfile has no effect for the display-output of the gs command. The colors when using the option are the same as without. A) Example using the files provided in ./ghostpdl/gs/toolbin/color/icc_creator/example: Executing both commands in parallel and comparing the colors of the open windows: $ gs gs tritone.pdf $ gs -sDeviceNProfile=artifex_tritone.icc tritone.pdf Result: Both windows display the same colors. Expected: Both windows display different colors B) Example using the attached test.eps which has an alternate colorspace of very different colors than their names suggest. Executing both commands in parallel and comparing the colors of the open windows: $ gs gs test.eps $ gs -sDeviceNProfile=artifex_tritone.icc test.eps Result: Both windows display the same colors. Expected: Both windows display different colors. The alternate colorspace has a very blue color instead of an orange, so the results here should differ strongly.
The first command in both examples should be without the second "gs", of course.
The DeviceN ICC profile handling appears to have gotten broken when we went to a delayed initialization of the ICC profiles. I will have a fix for this soon.
Fixed with http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=6c28ba38b907ec1c6a5755669ea0ecb55b95f8cc
Thanks!
