Setting a desktop background image so it "Fits the Screen" on Mac computers?

[ogaynor]

HI. I know how to push an image to my machines and how to set and lock the image as the background. What I'm having trouble with is setting the desktop settings so that the image is displayed as "Fit to Screen" instead of defaulting it seems to "Fill Screen".  The later doesn't display the entire image (which is basically a list of rules for my students to always see).  This is on Macbook Air laptops.

Is there any way to force how a background image is displayed once it's pushed and set? Via script, within Jamf itself, etc?

Thanks!

You can achieve that with the desktoppr tool: https://github.com/scriptingosx/desktoppr

Thanks! I'll give that a try and see how it works.
