CogOCVMaxPoseHelper InitialPoseEstimate Method

Cognex VisionPro

Compute an initial estimate of the desired pose using the currently set Font, FontRenderParams, and Text. This estimated pose will size and position the current text to fit easily within the center of the supplied image. The computed pose will be cached internally as well as returned by this method.
