When I tried to load 2GB tiff file, I got an "out of memory" error.
I have 512MB memory, but I set virtual memory to 5GB.
Is it possible to cut the big tiff file into several sub-images
without loading the whole image?

There are two potential causes:
1) .NET tries to put all 2 GB in a single object and AFAIK even 64
bit .NET limits single objects to 2 GB
2) the in memory object may actually use more space than the on
disk object
