I am new at programming with the tiff library. Is there an archive available that explains using 32bit reals within tiffs?
The good news is that you just set TIFFTAG_BITSPERSAMPLE to 32 and TIFFTAG_SAMPLEFORMAT to SAMPLEFORMAT_IEEEFP, and provide the right data, 0 is black, 1 is white.
The bad news is that few software packages will understand your files and that none of the compression options will do a very good job at reducing your file size.
