image from clipboard problem
Last modified: 2018-05-24 16:14:42 UTC
1. open pink_stain.png - it is OK Use GIMP 2.8.16 (Win32) 2. Convert pink_stain.png to pink_stain.rgba with vertical flip (using ImageMagick convert.exe) Use pink_stain.bat 3. BITMAPINFOHEADER + pink_stain.rgba = pink_stain.dib 4. copy pink_stain.dib to Clipboard Use InsideClipboard.exe and "Load From pink_stain.clp File" 5. Create new empty transparent image 800x600px and paste (ctrl+v) image from Clipboard 6. There is PINK STAIN on green dice corner!!! 7. There is no pink stain in other softwares after paste image from Clipboard

Um, that sounds a bit like an effort :) What happens if you simply copy the image to the clipboard in another application and paste it to GIMP?
I would imagine that someone going to such great length to reproduce the behavior might also be able to explain what exactly is happening here - bugzilla77, did you write all the tools involved here yourself, and can you tell us what exactly in the file is causing this?
The problem is that the data in DIB format may contain alpha channel, but Gimp ignores it.
