CogImage16Range.SetPixel Method

CogImage16Range SetPixel Method

Cognex VisionPro

Set the pixel and mask values at a given pixel space location. Note that setting VisibleValue to false on a CogImage16Range whose root currently has a null mask root will cause an appropriately sized and populated mask root to be created. The opposite is not true: setting the sole non-visible mask value to visible will not cause the mask root to be set to null.
