I'm trying to create an app like pain, to draw. But the thing is that i want it to draw only over an image and i don't want that image to be defined as background. Could anyone point me in some direction?
would appreciate any help.
Im trying to see and image though a circle, having another image in foreground, im using this code, but it only works if the foreground image is darker than the one in the back. would appreciate any help.
