services.xserver.desktopManager.wallpaper.mode
The file ~/.background-image is used as a background image. This option specifies the placement of this image onto your desktop.
Possible values:
center: Center the image on the background. If it is too small, it will be surrounded by a black border.
fill: Like scale, but preserves aspect ratio by zooming the image until it fits. Either a horizontal or a vertical part of the image will be cut off.
max: Like fill, but scale the image to the maximum size that fits the screen with black borders on one side.
scale: Fit the file into the background without repeating it, cutting off stuff or using borders. But the aspect ratio is not preserved either.
tile: Tile (repeat) the image in case it is too small for the screen.
