Set
whether a black-to-white change or a white-to-black change should
be recog
nized as a density change in the specified region.
Edge No.

[0]
Specify the edge number used to extract edges.
Edge numbers are assigned to detected edges starting from 0 and in the
directio
n from the st
art point (the arrow) to the end point (the arrow point)
in the selected region.

Set the density change level to be detected as edges.
The upper limit of edges can be set only when the measurement method
is "Derivatio
