Tiff is an complex format to serve very different needs.
The most simple way to read tiff data is with
TIFFReadRGBAImage(tif, width, height, buffer, 0);
all data are represented as RGB with alpha, 8 bit.
The tile interface is to speed up the reading for tiffs saved in an tiled
fashion (versus stripped tiffs - the other way to store data in tiffs).
To read more look in the documentation html/libtiff.html. It is very
helpful.
