Images are rectangular. To copy a polygon, you are only copying part of
the image. Lets say you have a black triangle on a white background.
The process would be something like:
look at the first pixel of the source image.
if the pixel is white, move on to the next pixel
if the pixel is black, change the corresponding pixel in the destination
image to black
Move on to the next pixel
Using a couple of loops you can selectively blend part of an image.
