Linear Measure
This gage operation is available when you select either the binary gaging
mode or the gray scale gaging mode. The linear measure operation measures
the distance between any two edges along the length of the gage. Figure 7.13
shows a linear gage using the linear gaging operation.

Note that the upper part of Figure 7.13 shows all ten edges as you would see
them after setting the edge detection parameters. Each detected edge is
indicated by a cross (+) symbol.
X Position
This gage operation is available when you select either the binary gaging
mode or the gray scale gaging mode. The X position operation measures the
absolute horizontal position of a specified edge along the length of a gage.
The X position is reported in pixels, with the origin (0 coordinate) being the
left boundary of the image.
Figure 7.14 (page 7–15) shows a linear gage using the X position operation.
In this example, the X position of the selected edge is 164 pixels from the left
boundary of the image.
