--- Comment #5 from Maik Qualmann <metzping...@gmail.com> --- digiKam uses a checkerboard as a background for transparent thumbnails by default. 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. Maik -- You are receiving this mail because: You are watching all bug changes.
