Digital geometry

right|upright=0.45|frame|This example shows an image with a portion greatly enlarged so that individual pixels, rendered as small squares, can easily be seen.

dot matrix data structure, representing a generally rectangular grid of pixels, or points of color, viewable via a monitor, paper, or other display medium

pictures encoded as binary data

formula that the area of a planar polygon whose vertices all have integer coordinates equals the number of interior integer points plus half the number of boundary integer points minus one
