This fix transparent alpha channel or only >0?
Hello, The patch makes Wine calls GdiAlphaBlend() when at least one pixel has a non-zero alpha channel. If all pixel have alpha channel 0, then the image is considered opaque (this will be wrong for full transparent images, but who would use a full transparent image, anyway?). The blending function uses the full alpha channel range (0-255). If you see artifacts in the transparent image, that is another issue. (My tests show that the current Wine alpha blending function doesn't give a smooth alpha result). Regards -- Do not reply to this email, post in Bugzilla using the above URL to reply.
