Hello world,

I'm devolloping a DOS based application that handles TIFF files. Actually I have two items on my TO DO list:

I've been implementing the TIFF G3 reader using tries for about a year. I've both the CCITT standard and a recent beta of Sam Leffler TIFF library, but I still have to understand it. Any hint welcome.

It seems to me the TIFF library doesn't support YCbCr. If I'm right, Is the use of YCbCr disrecommanded or (the usual thing) am I just overlooking some files in TIFF library.

I could make good use of a set of test TIFF files: planar and packed YCbCr files, Palette files with extra samples, TIFF files with more than 8 bits/pixel, even some CIE Lab files. I would like to be sure my viewer aborts gracefully as recommended. If anyone know where to get those, I'll be gratefull if he could let me know.
