Follow-up Comment #2, bug #57335 (project gnustep):
[comment #1 comment #1:]
> the white bits where shown as black. Is this the bug you are reporting?
Yes.
> What you did is switch off this conversion.
Yes, but not as a "fix", I was hoping that it might give you a clue what's
going wrong.
> And for simple data where alpha is either 1 or 0 this results in correct
images.
I just tried with a half-transparent image (alpha 0.5) and to my surprise the
conversion is correct with current code. But I'm afraid that "simple data" is
quite a common case, especially for icons.
