Subject: Copy / merge transparent looses palette?
Download (untitled) / with headers
text/plain 211b
Copying a palette-based image (with 3-4 colours) that has a transparent backgroud, using the merge* methods, seems to loose palette, and produces an image of a solid colour. Let me know if you would like a demo.

I found a fixed libgd bug at https://github.com/libgd/libgd/blob/master/tests/gdimagecopyresampled/bug00201.c with gdImageAlphaBlending and gdImageCopy vs the better gdImageCopyResampled. so upgrading libgd might help. -- Reini Urban
Looks like a libgd problem. No feedback -- Reini Urban

The root of this problem would be in libgd, not at the Perl layer. Have you tried updating your libgd version?
