Spanned wallpaper sizing could be better

[tristan-shelton]

I have a kind of unusual monitor set up with two in landscape and a third in portrait orientation. When I try to span a wallpaper in Cinnamon instead of the expected result of the wallpaper covering the whole area as in other desktop systems, it only seems to cover the smallest area. Here's a reporesentation of what I have and the result I'm getting:

What I would like is for the wallpaper to fill a bounding box that encompasses all monitors and zoom to fit that with cropping as necessary.

This seems to be an issue in gnome-desktop but I'm posting it here since I don't use Gnome. The responsible file looks to be /libcinnamon-desktop/gnome-bg.c but I don't have enough of a grasp of what all the functions do to figure out where the exact problem lies.

@tristan-shelton are you still experiencing this issue?

Not sure this is Mint or Cinnamon related.
My setup: Debian, Cinnamon, Dual monitor.

I can set zoom: keeps aspect ratio, image is maximized, cropping occurs, there are no left-overs (solid color) on any screen border. The image and effect is duplicated at each screen.

I can set spanned: image spans across monitors, but image is sized so no cropping occurs. It keeps the aspect ratio, and plenty of left-overs depending on the size of the original image.

There are forums telling users to manually edit the background image so it fits the spanned monitors resolution sum. It works. Not fair toward collectors.

We should have spanned and zoom at the same time. To span, then behave like zoom taking in account the whole resolution set sum.

Side note: I would love to collaborate directly to the algorithm, but I am at very early stage of Linux, and would not know where to start.
