Adam7
<graphics, algorithm> One of the progressive coding methods used in PNG
images. Adam7, named after its author, Adam M. Costello, consists of seven
distinct passes over the image. Each pass transmits a subset of the pixels in
the image. The pass in which each pixel is transmitted is defined by replicating
the following 8-by-8 pattern over the entire image, starting at the top left:
1 6 4 6 2 6 4 6
7 7 7 7 7 7 7 7
5 6 5 6 5 6 5 6
7 7 7 7 7 7 7 7
3 6 4 6 3 6 4 6
7 7 7 7 7 7 7 7
