Computes the smallest rectangle containing a region.

Name Type Description
inRegion Region Input region
inBoundingRectangleFeature BoundingRectangleFeature Determines what kind of bounding rectangle will be computed
inReferenceAngle Real The middle angle of the valid range of the output rectangle's angle
inRectangleOrientation RectangleOrientation Orientation of the output rectangle
outBoundingRectangle Rectangle2D The smallest bounding rectangle of the input region
outCenter Point2D Center of the bounding rectangle
outLongSide Real Length of the bounding rectangle long side
outShortSide Real Length of the bounding rectangle short side


The filter computes a rectangle with the smallest possible selected feature that contains all pixels belonging to the input region. The angle of the resulting rectangle is then normalized as in the NormalizeRectangleOrientation filter.


  • If the input region is not guaranteed to be non-empty, precede this filter with SkipEmptyRegion.


RegionBoundingRectangle performed on a sample region with inRectangleOrientation set on Vertical.
