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?

TIFFReadScanline would be a valid way to do it, if the image contains strips, as opposed to tiles. Best read http://www.remotesensing.org/libtiff/libtiff.html#Scanlines, and the next few topics on that page.
