Ouuhhh...I...I... huh...I haven't even thought about that, hahaha!
Hmmmmmmmmmmmmmm.... <that's me thinking>
Two things you might find interesting:
- do what you were thinking about, take the image of what you want to "copy".
- go into a new layer, activate [i] again and then hit [ctrl]+[i]. This will paste your image onto the layer exactly how and where you took it.
- then erase around it what you do not want to keep.
- then delete the brush image (if it's the only one, just hit [shift][i])
- now hit [i] again to take that new image
OK, now you have your piece isolated as a brush image.
- use your mouse now and brush #10 [0] (I should really say 10...my fault for keep calling it #0, I apologize).
- the only tricky part is setting the size "correctly", but definitely turn off pressure based size!
- hit [a] to lock the rotation
- use white color
- with the mouse you can now place the image in the new location. You could even hold [Ctrl][a] (or [shift][a]) to rotate it differently, if you wished.
- In the Brush Image GUI you'll see the yellow buttons along the bottom of it [col][= ][ ]. The empty one in the corner is your image mode. With it on, it will use the material amount, but if you turn it off, it will flatten the image. You can use that, too, to get your canvas texture to poke through, by the way, no need to reimport your png.
So, yeah, with a bit of inventiveness you can get a great deal of options with what's there already! I really didn't think about using brush images for that purpose. I was going to write a whole transform section and all that, which I still will, but this gives already some opportunities to get a bit of that, including scaling and rotating, of course.
