I'm trying to make an image with 2 layers: one is a circle that I'm using as a background (and everything outside the circle is transparent) and the other is a selection that I've copied that I want to paste over the background. Is there a way to make it such that the selection I'm pasting will only cover the background image and if any parts of the selection that I'm pasting go outside the background image into the transparent parts of the image that the transparent section will remain transparent?
I've been doing it an ad hoc way of just erasing parts of the layer that I'm using to paste and checking for transparency underneath but that's pretty time consuming. I assume there's a better way?
edit: also, vice versa: is there a way so that if I have a selection that has transparent sections that I paste over a background, that the selection I'm pasting will have it's transparent sections not overwrite none transparent sections of the background? I mean, outside of using magic wand to select everything except the transparent sections and just pasting the parts I selected using magic wand over.
