Scanning docs

[David Halliday]

Unh...  How many colors deep was the GIF file - if you are scanning
schematics, there should only be two colors and with this, GIF will far far
outshine JPG.

JPG introduces very nasty aliases on straight lines - it was designed from
the ground up to reproduce continuous tone images ( photographs ) and was
never intended to be used on line art.

I seem to remember a modestly compressed 2-color JPG file being about five
times larger than the same 2-color GIF file when properly encoded.

-> Hi Guys,
->
-> Thanks for all the responses! Consensus of opinion indicates it is
-> between JPG, GIF and PDF.
-> Unfortunately I don't have Acrobat so PDF is out (sorry Proteus).
-> I did a quick test of file sizes between GIF and JPG and a
-> file that is
-> 125Kb in JPG turns out to be 486Kb in GIF.
-> So as a trade off between quality, speed of transmission and Internet
-> compatibility, I guess it will be JPG...
