Now, the canvas show black if images are equal, but this is not ok,
If we show black on black pixels this is weird.
It's needed show all matching pixels as transparent pixels.
If there are only a few pixels that doesn't match the canvas seems empty, it's needed to put a border in the generated canvas.
