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 value too large. If the value is too large, the detection time gets longer and may result in false detection. Also, a value greater than 4096 cannot be set in Correlation and Geometric objects.
