This problem causes The Panorama Factory to occasionally produce
stitched images where adjacent images overlap by just a tiny amount.
The images appear to simply be placed side-by-side rather than properly
overlapped. The problem applies to fully-automatic and
semi-automatic stitching methods.
This problem occurs because the minimum and maximum overlap percentages
on the Alignment properties dialog do not work properly for tilted and/or
rotated images. The overlap percentage computation does not take into
consideration that there are transparent pixels at the sides of the
images. So the overlap percentage tends to be overestimated.
