--image-bg fails on wallpaper #575

Open philzin opened 3 years ago

philzin commented 3 years ago

I'm currently on version 3.6.1-1 on Arch and some of the wallpaper setting options fail to properly set the image background color. The option --bg-center is the only one that properly sets the color according to the argument of -B. All the other options `--bg-fill, --bg-scale, --bg-tile' result in a black image background.

Can you show the context in which this is being used? As the --bg-tile and --bg-fill commands shouldn't have any visible background left to colour.

I was trying to use images that had transparent parts, like a hexagonal grid where only the edges are filled.

avlec commented 3 years ago

Do you have an example image that I could use for testing?

philzin commented 3 years ago

I just had the issue with this image. The command I ran was feh --no-fehbg --bg-fill grid-png-transparent-pic-18.png -B white and my desktop looks like this, where the image in the background is my previous wallpaper.

Sorry to pester you more, but it's helpful to know your output of feh -v and specifically if your setup is using Xinerama. (because of this line https://github.com/derf/feh/blob/master/src/wallpaper.c#L494) But the soultion to your problem should hopefully be quite simple.

here's the output: feh version 3.6.3 Compile-time switches: curl exif inotify help stat64 verscmp xinerama my setup is using Xinerama, although I just tested without it and rather than using my old wallpaper it seems to default to black as the background. To test without Xinerama, I inverted the colors so that the grid is white instead and no matter what I pass to -B, I get the grid with a black background, whereas again with --bg-center it respects the color I choose
