RotationAngleRanges Property (Read Only)
Syntax
CWIMAQMatchPatternOptions.RotationAngleRanges
Data Type
Purpose
Collection of angle ranges, where each range specifies how much you expect the color template pattern to rotate in the image.
Remarks
Each range is specified by a lower angle and an upper angle, both of which are expressed in degrees. The rotation angle ranges are part of the setup information for the CWIMAQVision.MatchPattern2 method if you set MatchMode to cwimaqMatchRotationInvariant. The method ignores this property otherwise. Each range in the rotation angle ranges specifies how much you expect the template to be rotated in the image. To decrease the search time, limit the degrees of rotation in which you expect to find the template image. Leave this collection empty if you want all the angle ranges to be considered when performing a rotation-invariant match.
