Not an ideal solution but below worked for my situation. Like with a lot of UMG stuff, slapping more scale and size boxes can sometimes do the trick:
before:
- Border (that is display at 1:1 pixel ratio to the original image but we want to display smaller)
-- Image/whatever
after:
- Canvas Panel (Anchors: fill parent size)
-- Scale Box (Stretch: User Specified {desired image size divided by actual image size}, Anchors: fill parent size)
--- Size Box (Min desired width: {actual image size}, Min desired height: {actual image size}, Anchors: fill parent size)
---- Border (Anchors: fill parent size)
-- Image/whatever
If you’re familiar with UMG you may be more familiar than I am and notice some things in the above solution that aren’t necessary (or that I accidentally missed?). This is just to point folks in the right direction so there is something somewhat usable on this post
hope this helped
