Density change
• Absolute value
(only when the
mea

urement method is
"Derivation")
• [Light → Dark]

h
t
Select whether a black-to-white change or a white-to-black
change
should be recognized as a density change in the
specified region.
Edge No.
0 to 99
[0]
Set the edge number used to extract edges.
Edge numbers are assigned to detected edges starting from 0
an
d in the directio
n from the start point (the arrow) to the end
point (the arrow point) in the selected region.

width of a density
0 to 100
[50] to [100]
• Value (255 at the
maxi
mu
m) of density
[20] to [255]
Set the density change level to be detected as edges.
The upper limit of edges can be set only when the
mea
s
urement method is "Derivation".
