PostScript :: IMAGE - Drawing Bitmap Images
Operator: width height bpp data image
This operator draws a grayscale image in the unit square from (0,0) to (1, 1). The source information is a raster image width pixels wide by height pixels high. Each pixel is represented by bpp bits. The data operand can be a number of things, but is usually a procedure that returns a string of bytes with the grayscale data each time it is called. The procedure will be called repeatedly until all pixels have been processed. The image is processed from left-to-right, top-to-bottom.
Example:
%!
100 400 translate
10 10 scale
26 34 scale
26 34 8 [26 0 0 -34 0 34]
