Scaling Range
Scaling Range allows you to set a range from a low of 0.8 to a high of 1.2. In Run mode, this will enable matches
to occur even with slight variations in shape from the reference shape.
Tool Timeout and Absolute Positioning
Set a timeout in milliseconds that determines how long the Geometric tool will attempt to determine whether
a pattern is good or not.
Select Force to Absolute Positioning if you want to change the Geometric tool from relative positioning to
absolute.

Count tool. This reference shape is subsequently used to locate all similar shapes in new images by searching
inside the Search ROI. Geometric Count returns the following information:
