I am looking for some code that will take a set of tiff images and convert them into one large tiff file suitable for faxing.

I am at the moment using fax2ps piped to gs, and this work well. It is however slow and involves a lot of unneccessary conversion and CPU time.

I have had a look at tiffcp and fax2tiff, but find that fax2tiff does not like my tiff images, which is odd since fax2ps does. %-(

tiffcp will not convert between color spaces. fax2tiff takes raw g3-encoded data as input, not tiff.

Tiffcp seems to work, but the result is not liked by flexfax. Maybe I am just using the wrong options but it complains that it is not a bilevel image.

yes. if you have a color image then you need to convert it to a bilevel image and encode it in a format for faxing. you don't tell enough about the images that you are working with, but perhaps something like

tiff2bw a.tif b.tif
tiffdither -f b.tif c.tif

will do what you want. in the long run, if you are doing lots of image manipulation, you may be better off using a more general package like the pbm tools.
