Digital BW, The Print

I recently bought a Canon digital camera that came with a software program
called Photo Stitch that allows one to stitch images together into single
panoramas, etc.  It works great with the camera's digital output, but it's
limited when stitching film scans.  Is there a program similar to this that
works well with large scanned files?
