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. _______________________________________________________ Reply to this item at: _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
