As Bart Lateur suggested, libtiff or something based on it is probably the way 
to go. On UNIX the plain libtiff distro includes binaries that you can dissect 
the image file with. Going on from there, on UNIX you'd have access to 
ImageMagick or Gimp to start with. There's a Mac port of IM that also makes 
analysis and processing tools available, but no viewer (I think).

I think Bart also suggested Photopaint - I've been away from MacOS for the 
better part of the year, but I recall obtaining a free copy of CorelDraw and 
Photopaint from the Corel website late last year. I think it was version 8, and 
sort of "lite". Worked fine, though.

Finally, on MacOS there is always GraphicConverter. If this doesn't do it then 
that TIFF is hosed. :-)
