I've searched the FAQ and the archives, and I've seen some discussion about 16 bit grayscale images. But I haven't seen the answer to:
how can I use libtiff to read a 16 bit grayscale tiff? I don't want to display it, and I don't want it converted to 8-bit. I just want access to the 16-bit values.
My guess is that I should use something like TIFFReadScanLine. Is this correct? Is there a way to read the entire image in one call?
