Selectable chips & boost programming

[Marteney, Steven J.]

I noticed a lot of you guys use JPEG to compress black and white images.
Not the best choice since JPEG typically eliminates the high spatial
frequencies necessary to keep the edges sharp.  This produces a lot of
artifacts and also "smoothes" lines.  I've downloaded some schematics and
wiring diagrams and they can look pretty crappy because of the compression.

For these true black and white files it would be better to use TIF, GIF, or
preferably PCX since run-length encoding methods will keep the true B/W
nature of the image.  These methods SHOULD also produce smaller files,
depending on the content.  This, of course, assumes everyone can read those
formats.  I realize JPEGs are the web standard.

Just a suggestion.
Steve
