Oh, sorry - misread your question. Yes, bad colour shifts are quite common if you use the default approximation (which doesn't take the colour profile into account). For better results, you want PIL 1.1.7 with littlecms and the ImagingCMS module (see the list archives for pointers to the development repo). </F> _______________________________________________ Image-SIG maillist - Image-SIG@python.org http://mail.python.org/mailman/listinfo/image-sig
