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?

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?)

Is it also possible to spllit a single strip into multiple strips in a singlle TIFF fille. The problem is that we get single strip tiff files from the customer and some times we can't allocate enough memory for this singe strip (memory to fragmented). Yep, I'm ware of 3 GB address space on Windows NT and 64 bit but onfortunately we're Still one Windows 2000. Thanks Rob **** Q.I.
