Hey list
i have just tried using PIL to crop and resize CMYK images (with CMYK as end
result, no color mode conversion). I must say i was surprised how awfull the
result look. Even though PIL is not supposed to touch the color mode, colors
is totally fucked up in the modified image.
Is that

Can you
I ran into a similar problems with CMYK and I think it's because libjpeg
doesn't interpret the CMYK data correctly (possibly stripping a color profile).
This is easily verified using libjpeg standalone tools (like jpegtran that you
can compile when compiling libjpeg).
On the other hand, using
The jpeg plugin doesn't handle CMYK properly - I've posted patches in
the past... trivial to fix.

Thanks for the explanation, I followed your link to the thread but I couldn't
find the attachement you mentioned in it (because I'd like to use your patch !).
Is PIL still maintained (considering the patch is 3 years old) ? Or is there a
specific reason it's not included in PIL ?
