Libtiff has support for 8, 16, and 32 bit int per sample and 32 bit
ieee-float per sample images.  Support for signed ints might be limited
to 16 and 32 bit.  I'm not sure to what exetent libtiff supports tiff's
options for 64 bit ieee float, complex signed int and complex ieee float
sizes and formats, beyond recognizing and reporting them.

IIRC, libtiff.org was hijacked some time back.
The real homepage for libtiff is:


Also, PNG (and libpng) supports 16 bit per sample images, and OpenEXR
supports arbitrary sizes, much like tiff.
