I’ve searched for the answer here and online, but to no avail.
MSPaint only allows 90 degree increment rotations, so I want to tessellate using Paint.net instead. But when I clone an image, it comes out with a white “shadow” around the whole edge (see attached small image). In MSPaint, all I have to do is hit the “transparent” button to get rid of the “shadow,” but in Paint .net, I don’t know how.
I’m adding an example of my tessellations.
