AVL.RegionBoundingRectangle Method

Computes the smallest rectangle containing a region.

Namespace:	AvlNet
Assembly:	AVL.NET.dll

Syntax

public static void RegionBoundingRectangle(
	AvlNet.Region inRegion,
	AvlNet.BoundingRectangleFeature inBoundingRectangleFeature,
	float inReferenceAngle,
	AvlNet.RectangleOrientation inRectangleOrientation,
	out AvlNet.Rectangle2D outBoundingRectangle,
	out AvlNet.Point2D outCenter,
	out float outLongSide,
	out float outShortSide
)

Parameters

Name	Type	Default	Description
inRegion	AvlNet.Region		Input region.
inBoundingRectangleFeature	AvlNet.BoundingRectangleFeature	MinimalArea	Determines what kind of bounding rectangle will be computed. Default value: MinimalArea.
inReferenceAngle	float	0.0f	The middle angle of the valid range of the output rectangle's angle. Default value: 0.0f.
inRectangleOrientation	AvlNet.RectangleOrientation	Horizontal	Orientation of the output rectangle. Default value: Horizontal.
outBoundingRectangle	AvlNet.Rectangle2D		The smallest bounding rectangle of the input region.
outCenter	AvlNet.Point2D		Center of the bounding rectangle
outLongSide	float		Length of the bounding rectangle long side
outShortSide	float		Length of the bounding rectangle short side

Description

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.

Examples

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