CHECK
2-12-(29)
When the bottom right coordinates are specified, the region will be set
and the screen in (a) will return.
Use the following procedure to fix the region.
Measurement Objects with Variable Widths Only
Draw the edge detection region so that the measurement region Y coordinates
will remain the same for both the upper and lower edges. The upper and lower
edges will always have these edge points.
Left edge region
The measurement region will adjust to the right
and left edges only before measurement is performed.
