Copying and pasting a non-rectangular area of screen

[Petr]

Yeah, I dealt with it. Finally, I used a transparent background, I selected the farthest coordinates from the array of points that bounded the polygon, thus obtaining a rectangular slice with a transparent background, and I sent that to the new handle of the new image with the _PutImage command. It's significantly faster than solving it point by point. I'll try to find it or write it right away.
