You're passing in floating point coordinates to crop and paste, and it
appears that crop and paste doesn't necessarily agree on how big the
region is when you do that.  This is probably a buglet, but you should
use integer coordinates anyway; just change both calls to saveImg to:


(or do the rounding inside the function), and paste should work.
