We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I am trying to create a sort of mirror effect so that when I draw in a certain area it is then captured, transformed and finally copied to a specific area of my display.
Of course my first idea was to use the copy() or blend() functions but unfortunately it is a straight copy to a different area and does not allow us to actually apply transformation to the copy. Also I thought of actually directly working on the pixels array but I was wondering if that would impact performance.
Does any one ever did that or has an idea how I could achieve that?
