Dear all, I am trying to work on a low level issue in OpenJPEG. For reference all steps (*) are logged at:
http://code.google.com/p/openjpeg/issues/detail?id=311 I have little experience with ICC profile, so I was wondering if I was doing anything wrong. I have extracted the ICC profile from a JP2 file, and then applied it on the decompressed JP2 (before color conversion of course). I thought this would generate identical results with what a referenced software for JPEG 2000 (kakadu) would be doing but it is not. My question is can I simply use tificc (lcms2 2.5 from debian) this way: $ tificc -ifile5.jp2.icm rgb.ppm.jp2.tif file5.j2k.tificc.tif where: $ wtpt file5.jp2.icm Show media white of profiles, identifying black body locus. v2 Restricted ICC profile describing ROMM-RGB WhitePoint : D50 XYZ=(1.0, 1.0, 0.8) Lab=(100.000, 0.001, -0.000) (x,y)=(0.346, 0.359) Hue=319.82, Chroma=0.00 Should I be paying attention to any particular flag in `tificc` before applying this particular ICC profile ? Thanks for suggestion, [*] You can download file5.jp2.icm or rgb.ppm.jp2.tif directly from the openjpeg bug referenced -- Mathieu ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
