So I was fiddling in paint when I noticed that the pixel coordinates start at 0 and end at the resolution value. So for a 100x100 picture, the leftmost pixel would have the coordinate (0; y), and the rightmost -- (100; y). Thing is... if the enumeration starts at 0, doesn't it mean that the actual resolution of the picture is 101x101, because of the x=0 and y=0 lines? I might just be retarded, but please explain if I'm missing something.
