It sounds like you've got libtiff to build and work, the question is how to handle compression? I use libtiff 3.7 in a scanning/imaging library that is built with MSVC 6 (though not for much longer...) I can share some of my code. There isn't really any special code for handling compression during reading, libtiff just takes care of it. Actually,compression doesn't take much code either. In fact, now that I look at the code, most of the complexity is in dealing with all the varieties, and quite a few 'oddities' of TIFFs we've encountered over the years... My code uses a lower-level library to handle images in Windows 'DIB' format, don't know if that would make it unsuitable.
