Remarks

The SearchWinHeight property is available for the Blob, Correlation, Geometric, and ImageOp objects.
Each of these object types have similar rectangular Search Windows used to define the area to search
within. The SearchWinHeight property is set automatically when the user drags the upper or lower
horizontal window handles for the Search Window of each object type.

There are cases where the user may want to expand or position the Search Window dynamically and for
that reason the SearchWinHeight property can also be set from the SPEL

Language.

Do not the set the SearchWinHeight setting too large. If the value is too large, the detection time gets
longer and may result in false detection.
