Edges
This gage operation is available when you select either the binary gaging
mode or the gray scale gaging mode. The edge counting operation counts the
total number of edges that are detected along the length of the gage.
Figure 7.12 illustrates a linear gage using the edge counting operation. In this
example, the gray scale gage finds ten edges, one on each side of the black
rectangles.
Note that the upper part of Figure 7.12 shows the ten edges as you would see
them after setting the edge detection parameters. Each detected edge is
indicated by a cross (+) symbol.
