dop2000 thank you. I am working on a simple puzzle for chidren and I was looking for an easier way to dismember the image into pieces. (images 1 and 2)
the first thought was on tilemap but this action of "drawingcanvas" copies only the overlapping part of the "sprite", this worked perfectly. (images 3 and 4)
img - 1
img - 2
img - 3
img - 4
