CWIMAQShapeDetectionOptions.ScaleRange

Data Type

CWIMAQRange

Purpose

Specifies the range of sizes of the shape you expect to be in the image.

Remarks

The method ignores this property unless the MatchMode property includes cwimaqGeometricMatchScaleInvariant. The size is expressed as a percentage that represents the ratio of the size of the shape found in the image to the size of the original shape defined by the descriptor. The default range is 75 to 125.
