Remarks
The SearchWinWidth 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 SearchWinWidth property is set automatically when the user drags the left or right vertical
window handles for the Search Window of each object type. However, the width of an object's Search
Window can also be adjusted by simply entering a new value in the SearchWinWidth property.
There are cases where the user may want to expand or position the Search Window dynamically and for
that reason the SearchWinWidth property can also be set from the SPEL+ Language.
Do not the set the SearchWinWidth setting too large. If the value is too large, the detection time gets
longer and may result in false detection.
