The SearchWinTop 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 SearchWinTop property is set automatically when the user drags the upper horizontal window handle
of a specific object's Search Window or moves an object's Search Window vertically. However, the Top
position of an object's Search Window can also be moved by simply entering a new value in the
SearchWinTop property.
There are cases where the user may want to position the Search Window dynamically and for that reason
the SearchWinTop property can also be set from the SPEL
+
Language.
