I would like to use libtiff to read, process and write large 48bit per pixel TIFF images on a Win2000 and WinXP platform. Having been to your libtiff.html web page and downloaded much of the material pointed to by that page, I got confused by yet another page "Gnu Win32 Project" which it seemed I needed to learn, too, in order to use libtiff.

So I have two sets of questions -

  1. Can I use libtiff to read, process and write 48 bit per pixel (16 bits per R, G and B) images? That are about 500 MByte files? On a Windows platform?

Yes.

  1. Is there someone I can contact who would be willing to guide me about how to install and compile libtiff using my Visual C++ compiler?

Libtiff is free software so there is no dedicated support. Probably list members can help with your questions.

You might consider using something like GraphicsMagick (http://www.GraphicsMagick.org/) which includes libtiff along with a Visual C++ build environment (VC++ 6.0 & 7.0). There are also pre-built install packages for Windows (Built with VC++ 7.0). You would want a "Q16" (16-bit quantum) version to support your 48bit RGB files. GraphicsMagick is a lot bigger than libtiff, but it also provides APIs and utilities for image processing.
