Example
Add a "Width" edge to current inspection using the Graphic User Standard in STANDARD mode.
Select "Width" from the pull-down menu:
Position the control on the reference image in the work area: the pointer changes shape as soon as it
enters the work area. Left-click once at any position to create a
default rectangular ROI.
At the same time, the control features and the result of its
application to the reference image appear in the control panel.
Set ROI size and position as required, as explained above.
The result indicated by STATUS is also highlighted by the ROI
border changing colour.
As soon as values change, result is calculated without delay.
Let us assume that our reference is to be the distance between
points that are part of a bright object on a dark background.
A yellow line appears inside the ROI on the edges found; edges
are displayed as yellow dots that identify the limit values for
distance calculation.
Now use the sliders of the Min and Max fields to specify how far the measurements taken on master
images are allowed to deviate from the measurement you have just set and still be considered
acceptable (i.e. without triggering a control "Fail" status).
