A Quart of Data on a Pint-Size Screen

Q: How do you show a high-resolution color image on a 480- by 240-pixel display with four gray levels?
A#1: R emove plenty of data.
A#2: Look at it in pieces.
Symantec offers both solutions. One view displays the entire host screen on the hand-held PC through aliasing and pixel averaging. You really can't read much, but you can find your way around. The second view is a one-to-one display of the host screen's pixels. Only color information is lost, and you can see just a portion of the host screen at any one time. There are several commands for toggling between the two views.
