Calibrates the
geometric distortion caused by viewing a surface at an angle to the
normal. Examples of such distortion include low-magnification SEM
images of tilted surfaces or images of a viewing screen of a TEM. The
image should contain a feature known to be rectangular when viewed from
the normal. The user clicks on the four corners of this feature, and
from these coordinates the required correction is calculated and
applied to the image. Press the option key to preserve the aspect ratio
of the feature, otherwise the aspect ratio specified (see below) is
used. This correction can be applied subsequently to other images using
Apply Correction.
