Does anyone how any clue on how to read a TIFF file directly in a
filestream?
I know I can load the complete image into memory, but since this a 800+ mb
image, I usually get a "Out of memory" error.
Basically, all I have to do, is look up some certain pixel-values, so I
would guess that its just a matter of seeking to the correct bytes and parse
them to a color.

Can anyone give me some pointers on how to calculate the correct position in
the file, where I can get a certain pixel-value?
I'm complete off on this one, so any ideas would do (except the approach of
splitting the image up in several smaller images).
