jpg images

[Syed Zaeem Hosain (Syed.Hosain@aeris.net)]

Unfortunately, GIF only uses 256 colors in any given image (selected from a larger palette though). So, _not_ what I would use for high-quality photographs, but it _could_ be used for screen captures as long as there aren't too many colors in that screen.

I have tested JPEG output for screen captures and they are _not_ acceptable [to me] for this use purpose. Solid color (e.g., white) backgrounds, text, sharp color transitions, etc., will get speckled dots and edge smearing as well. Often, white backgrounds end up with light-gray coloring and these show visibly in documents with white paper backgrounds - you can see ink-jet printers trying to reproduce this light color in the output. Indeed, my new Canon ink-jet at home (which has a grey ink cartridge - cool!) would faithfully try to reproduce this, I think.

It is far better to use TIF (large files though) or PNG for screen captures. With true white backgrounds, on white paper documents, the result is very clean. In most of my screen captures, the PNG format has worked well - particularly when I need transparent backgrounds (which GIF does not support) which I can edit in Photoshop.

JPEGs should _only_ be used for photographs.

JPEG with the highest quality setting is fine for most screen shots, though I usually see smaller files from PNG or GIF.
