Scaling Background Image to Fit Workpiece

I have a project idea I was working on and imported an image for the background. I wanted to fit the image to the size of the workpiece. By using the % scaling feature I cannot get the image to fit properly. It fits top to bottom but overhangs the side.
Is there a way for this to be done inside CC or is a third-party software required?

It would be nice to be able to one stop shop, so to speak.
If a % is required for ease of programing, maybe a side to side % and a top to bottom % could be implemented.

I’ve imported images to the background, traced them manually, then scale the vectors.

That looks like it would trace well. What about using the Trace Image feature then scaling the vectors?


That sounds like it may be the route I may need to go.
