My questions are two:  First, is there any way to save to TIFF using
CCITT Group 4 compression under Photoshop?

And even if Photoshop doesn't permit this, is there any graphics
program that'll let me save a document to Group 4 TIFF using some color
other than white for the background?

Thanks to any and all who can shed a little light here.

I have an unfinished plugin[1] which uses libtiff
(http://www.libtiff.org/) to support a wider range of TIFF formats.
Currently reading is implemented, writing wouldn't be very difficult to
add. How badly do you want it? :-)

Libtiff also includes tools which can recompress your TIFFs as G4 (see
tiffcp).

 hi dennis,

up to windows 2000 you can use "imaging".

but, imho, tiff g4 is a fax compression so u will only be able to save black 
n' white.
