I tried making a custom brush from an image, but when I did that a red X appeared in the brush designer and testing in the test panel only painted the color white.
Are there restrictions for brush images? Also, I saw mention of a stamping tool on the brush window, but I don’t see this.
At a higher level, my reason for wanting to do this is a simple way to do quick image edits where I’ve rotated an image but need it to fill in a specific aspect ratio. Cropping the rotated image while keeping the items you want, you’ll often have empty sections of the image. These can often by “fixed” by just extending what was in the background of the subjects.
You can use the clone tool to do this sort of thing, but I find the clone tool kind of irritating to use. I thought maybe just making a brush from a selection of the background, doing an initial fill with that, then touching up if needed would be a way to go about that. Does that sound reasonable or is that a dumb approach?
