Package: lcms Severity: normal Tags: patch Ghostscript project embedded code copy of lcms includes a patch that seems not passed (or at least adopted) upstream, yet potentially relevant to do so and/or apply locally to Debian: http://git.ghostscript.com/?p=ghostpdl.git;a=commit;h=eac29c7
Here is the commit message for the main of above patches: >Fix so that the initial gray color spaces in the graphic state are >properly color managed. Previously, if we immediately started drawing >in the document with a gray color space, the initial un-managed color >space in the graphic state was used and this was not associated with >the specified gray source profile. With this fix we initialize the >stroking and filling color spaces to be ICC color spaces associated >with the profile for default_gray in the icc manager. Also a fix for >an issue in littleCMS. When merging profiles, littleCMS will often do >an optimization where it approximates 1-D LUTs with an exponent >operation for use during merging and interpolation of the profile >structures. If the curve is very steep, as in like a step function, >it should not do this approximation. This was an issue when we had >profiles that provided thresholding operations with their 1-D LUTs. >I spoke with Marti about this issue a couple weeks ago. This commit >will create over 6000 differences in the regression test. I reviewed >many of these and they all are minor differences in gray colors as >expected. These are differences where we were drawing unmanaged >colors. - Jonas -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
