The checkerboard pattern was a user request that worked a lot with graphics to estimate the position of the graphic in the thumbnail. You can also see in the thumbnail that it is a transparent image. Maik That makes sense. I still think it would be great to have choices to select transparency though. The checkerboard technically works, but not as aesthetically pleasing. I would agree with Kamo. It would be nice to have the option to turn this checkerboard on or off. I have a large number of tiff files that include an alpha channel containing IR data. The checkerboard effect makes them very unpleasant to work with. Git commit 4472b594382a4e2e11f3b1272cf4d30ed7ded1e3 by Maik Qualmann. Committed on 04/03/2021 at 21:07.

If the file exists under "~/.local/share/digikam/thumbnail/background.png", it will be used as the fill background. This "background.png" must have a size between 10-1024 pixels, it can be transparent, colored or a pattern.
