This is where colors get distorted. Wine uses default stretch blit mode (BLACKONWHITE) which distorts colored images on shrinking. According to my tests, Windows is doing halftone filtering in this case. I am attaching the patch which fixes this (or at least greatly improves the look of the images) and also has some basic tests suggesting that Windows controls stretch mode in CopyImage(). I could not find any documentation where this behaviour is discussed. The fix sets stretch blit mode to HALFTONE in CopyImage for colored images. While HALFTONE stretch blit is not implemented in Wine gdi dibdrv (and so the test still does not pass), STRETCH_DELETESCANS it falls back to looks more appropriate for colored images than STRETCH_ANDSCANS (BLACKONWHITE). -- Do not reply to this email, post in Bugzilla using the above URL to reply.
