oh, for alpha blending you obviously need the data in a format that
understands alpha!
[pix_film] on os-x outputs YUV by default, where there is now
alpha-channel, so you cannot apply an alpha-mask.
make sure that you get your data in RGBA colorspace, either by sending
the [pix_film] a [colorspace RGBA( message or explicitely by using
[pix_rgba]
