I use gimp for this - I just change the scale of the image (usually so that it's 800 wide). Hope This Helps!

Post #59,264 by broomberg 10/24/02 9:10:21 PM Reply	Yup I know I took the following 210147 a.tif and did: mogrify -scale 600x1200 -format jpeg *.tif 34815 a.jpeg.0 51699 a.jpeg.1 56333 a.jpeg.2 56718 a.jpeg.3 This cut the picture down to less than 1/4 the original size, and seems the limit on viewable. Which means I only save about 20%. Can I do any better?

Faxes would be "bi-level" images, and the best - (a6l6e6x) - (2) - Oct. 26, 2002, 10:31:36 PM EDT

I thought faxes support gray-scale? -NT - (Arkadiy) - (1) - Oct. 28, 2002, 10:11:22 AM EST

No. Group 3/group 4 compression of a fax is bi-level. - (a6l6e6x) - Oct. 28, 2002, 09:37:20 PM EST
