If the ASCII document is large enough, in theory you can represent any monochrome image with an arbitrary degree of accuracy. If line lengths or number are limited, though, this isn't possible. Essentially you just make some non-blank ASCII character represent a dark pixel, and use a blank for a white pixel. So with 768 lines of 1024 characters each, you can represent a typical video display. _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
