Subsampling = 2, 2

I've set up a 1280x1000 array for each Y, Cb and Cr section. I expect to see the Y array filled, and 1/4 of the Cb and Cr arrays filled, which will then be enlarged to the size of the Y array.

That's correct for subsampling 2,2... but you do realize that *you* have to enlarge the Cb and Cr data, right? libtiff doesn't do that for you.
