Overlaying an image onto part of a larger image

Hello. I want to place a square black&white image on top of the corner of a larger rectangle. This seems like it should a simple thing to do, but I can’t for the life of me figure it out. Even if the white part of the small image is visible, the black part either covers the rest of the larger rectangle, or it disappears as transparency. Tried “overlay”, “over” and “atop” composite methods; tried adding the small image to a large transparent rectangle first before compositing; but nothing seems to work.

Have you tried “under” ?

Need a different Composite Operation. Use Operation Over or Atop.

The over.TOP in your network should be doing the job but can’t tell why its not working from the uploaded image.

Thank you for your replies. It works with your text operator, but it doesn’t work with my png file loaded via the movieplayer TOP. Here’s the toe and png.

I think the problem is the grey/8 color of the image. I just don’t know why. I wish I could explain the why!

I used Affinity Photo to re-export the PNG as RBG/8 and the problem goes away.

If I make my own grey/8 image I have the same issue.

Thanks for testing that, @goblynn93

That’s pretty goofy. Can this be considered a TD bug?

Possibly. I’m not knowledgeable enough to know that answer. There may be some reason it works that way but at first glance it certainly looks broken.

I wish I knew more about why its happening instead of just figuring out how to fix it/work around it.
