You might look in http://www.libtiff.org There is a link for down-loading tiff library software near the top of this page. Near the bottom is a link "Building the software distribution" . That link has instructions for creating the library on Windows using Visual C++. p.s. I have code to open a bitmap file(BMP) and get the "matrix version" of it. I use the bitmap file as a texture in openGL. Hope this helps.
