The PNG image format does not support the YUV colorspace, instead it converts non-RGB colorspace to RGB before the image written. Try using an intermediate image format that supports YUV such as YUV or MIFF. _______________________________________________ Magick-bugs mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-bugs
