The 9x 16 Bit .tif images weight 1.2+ Gigabytes. What service will delivery these to you?
I have just run a few more tests. 8000x4000 I got a successful stitch. Tried again at "Print" values and it crashed again.
Stitching (when successful) is very, very slow, but quite accurate.
Tried stitching them on my 64 Bit machine with twice as much RAM and the program crashed every time at any size (even very small). Yet my 32 Bit computer stitched fine up to 8000x4000 using the very same image set.
This error message I have seen on both computers.
