Ubuntu 04.04.03

ImageMagick 6.7.7.10

CMYK source image

Convert to PNG

I do this:

convert f2856e00-c95a-4f22-b929-d84041520748 png: f2856e00-c95a-4f22-b929-d84041520748_m.png

If I do this on Ubuntu 14.04, then the image becomes brighter, but if on Ubuntu 12.04 (ImageMagick 6.6.9-7) or on MacOS (ImageMagick 6.9.3), then everything is fine.

Rummaging noted that if you specify the profiles, then the conversion will take place normally

convert -profile / usr / share / ghostscript d84041520748_m.png

I want to understand how to make the conversion happen without color distortion. Can indicate where these profiles are in configuration files?

    in my case, everything was decided simply. ImageMagick version 6.6.9-7 apparently has such a bug. updated to version 6.9.3 and everything became good (updated manually, there is no such version in the repositories)

      I also thought about it. But most likely not. Since the profiles CMYK and RGB are different. In my case, let's say, there is no profit from the default profile, I had to take Adobov profiles.
