Module: FoundationBasic

Computes the smallest rectangle containing a region.

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