<br>I did not know that for coloring I do not need pix_alpha. sorry. so with<br>pix_rgba and color I can color all white pixels. nice.</blockquote><div><br>I don&#39;t think pix_rgba is needed either.&nbsp; On OSX any image file with a working alpha can be directly uploaded to the GPU and the alpha should work.&nbsp; Also, Animation and None codec movie files will do the same.

</blockquote><div><br>pix_alpha makes a fake alpha channel from averaging the R G B channels.&nbsp; This is not the right object to use if the image already has a pre-computed alpha channel.&nbsp; It is possible that there is a bug in pix_alpha on Intel though.
