Chris,

Thanks, we use the TIFFReadEncodedStrip when we've determined the stripsize. From the documentation and from the LibTiff sources the interface is such that I can give a size of the data to read but I would expect a pointer back and read from that point on.

What do I miss?

Regards
Rob

Rob;

Just because the file has the entire buffer in one large strip doesn't mean you have to read it all into one large buffer at once. Allocate as large a buffer as you can, and read smaller strips of the file into that.

(how do you think professional programs read in files larger than RAM?)
