intended for continuous-tone images; i.e. photos. It applies image compression
by looking for gradual gradients of brightness and color from groups of adjacent
pixels.<SPAN class=296082803-05032007><FONT face=Arial color=#0000ff

color=#0000ff size=2>Actually, it generally transforms the image to a YCbCr
color space, applies chroma subsampling, then performs a discrete cosine
transform on each 8x8 pixel block in each channel, quantizes the resulting
coefficients, and uses entropy coding to store them with run-length
encoding and Huffman compression. But yeah, it makes straight lines and
edges look fuzzy. =]</FONT></SPAN></DIV>

are striving for is not a "multimode tracker" but a full-function APRS station
that happens to be mobile. The commonly-accepted usage of the term
"Tracker" is for a dumb (or should I actually say deaf") transmit-only
mobile that spews out posits periodically and can't receive
anything.<BR><BR><SPAN class=296082803-05032007><FONT face=Arial color=#0000ff

operation. I haven't implemented a GPS pass-through yet, but I
could. </FONT></SPAN></DIV>
