copyPixels should treat the following as if a solid alpha mask had been provided: bitmapData.copyPixels(src, rect, pt, null, null, merge_alpha); Currently, however, swfdec implements it as a noop. A branch which extends the copyPixels test to catch this bug, and additionally fixes it, is available from this repository: git://github.com/mental/swfdec.git The branch name is copyPixels-alpha-nomask
merged it, thx.
