Step G -- Crop the image
In this step, we crop the rotated image to remove extraneous white space.
If we want to, we can simultaneously flatten the perspective.
Crop command (New image menu).
Set cropping parameters as you wish, or keep
the defaults. If you have gotten everything right, the
Perspective correction option should create a conventional image that
preserves straight lines. You should not use perspective
correction if you plan to display the image in a VR viewer.
Drag the boundaries of the cropping region to
enclose the part of the image you want to keep.
Note that we allowed the
cropping area to include a little bit of the white background at the upper
left corner of the image. It is not unusual for a hand held panorama
to have a missing piece like this because it's difficult to be completely
consistent in photographing the rows. We'll fix this later with
Advance to Step H --Sharpen the image if desired
Back to Step F -- Assign
panoramic properties to the rotated image
