Hello again! My other thread was a bug report, so I conveniently didn’t request the thing that would have helped me avoid the bug altogether until it was fixed.
What I really want is the ability to use solid colors instead of always transparency in Trim To Edges nodes. Photoshop (et al) lets you trim edges based on a corner color or transparency at your choosing.
I know that InstantAlpha > Trim To Edges > Matte is a more flexible version of this request, but it’s three times the number of nodes and the nodes are pretty large
