It appears that profiles are being stripped when output is JP2.


I took one of the PNG Kodak Images (parrots) and opened in my old PS CS and assigned an AdobeRGB profile and saved with no compression as TIF. Then I converted to JP2:

http://www.fmwconcepts.com/misc_tests/kodim23.tif

Code: Select all

convert kodim23.tif JP2:kodim23.jp2

The result has different colors. But the Adobe profile did not follow to the output image. So I tried to assign it explicitly as

Code: Select all

convert kodim23.tif -profile /Users/fred/images/profiles/AdobeRGB1998.icc JP2:kodim23b.jp2

but the profile was not in the output image.

This may be the issue. I do not know if JP2 format allows profiles. I am not sure why it would not. But I am not an expert.

But the stripping of profiles could be a bug and causing the color differences.
