The following commit has been merged in the upstream branch:
commit e5776b8d76108d2fb616f19f88bb0ed55d0c2ff6
Author: flyashi <flyashi at 59b500cc-1b3d-0410-9834-0bbf25fbcc57>
Date:   Fri Jul 9 15:12:46 2010 +0000

    Fixed C++ port's handling of reversed barcodes:
     - BitArray.reverse() was inverting, not reversing, bits.
     - OneDReader wasn't reversing x coordinates of the result points.
     - OneDReader wasn't catching Binarizer exceptions properly.
    
    Issue 470 can be closed by this.
