Is there a way to automaticaly select an undefined area in a drawing. Some kind of a self contourning intelligent tool or a clickable adjustment of the contour line? It is quite difficult trying contourning an unregular area so it can be selected and move; parts of the background tend to follow. I would be glad to pay for that option.

Question: Can Paint.net Copy and move a selected item contour only, without the background as example: selecting only the head of a person and placing it on an other person image?
