Exporting a color indexed PNG with alpha adds an extra entry to the color map.
Windows 10
- Gimp 2.10.32
This a request to report the following. ........... If i export an indexed (palette generated from graphic-colors) graphic with transperencies as png, there appear weird things at reimport: After closing and reimporting there is always a random colored extra cell in the index-palette of the graphic. And often all pure black (all rgb channels 0) pixels are turned into transparency.
I decided to report it here: gimp bug-report But this needs an account and i cannot receive the confirmation mail .......
...but I do know it exists
Reproduction
Is the bug reproducible? Always
Reproduction steps:
- Export an indexed png
- Re-open the same image
- Check the colormap
…
Expected result: colormap is as created
Actual result: colormap has extra entry
