Stitched image displays incorrectly
after adjusting focal length or barrel correction
If you open an overlap region and then change then focal length or
barrel correction while the zoom is set to 100%, the stitched image will
be displayed incorrectly after you close the overlap region. This
problem makes it appear that some images were not rewarped. The
images actually are rewarped, but some of the overlap boundaries are not
updated properly. Therefore, the overlap boundaries have the shape
determined by the old image warping. This makes it appear that the
images are incorrectly warped.
Set the zoom to something smaller than 100% before adjusting focal
length or barrel correction.
If you experience this problem, there is no alternative except to
restitch the panorama. with the Restitch command (Image menu).
To avoid having the restitch change the focal length or barrel correction,
select I am certain of the focal length and deselect Automatic
correction of barrel distortion on the Camera properties dialog box
Corrected in V4.1.
