Properties
double	CenterX [get, set]
	The x-coordinate of the circle region center.
double	CenterY [get, set]
	The y-coordinate of the circle region center.
double	Radius [get, set]
	The radius of the circle region.
Properties inherited from ILRegion
LPVInterpolationMethod	InterpolationMethod [get, set]
	The interpolation method used in image reduction.
double	ReduceAngle [get, set]
	The angle of the reduced result. By default, it's 0. A non-zero value means we'll rotated the reduced result image by the angle clockwise. More...
double	ReduceScale [get, set]
	The scale of the reduced result. By default, it's 1. Change this value to scale the reduced result image. More...

Detailed Description

This interface expose APIs to create/modify a circle region object.

To use this interface, you should create a LCircleRegion object.

Example Code

C++

ILCircleRegionPtr circleRoi = LCircleRegion::Create();
circleRoi->SetPlacement(20, 20, 100);

C#

LCircleRegion circleRoi = new LCircleRegion();
circleRoi.SetPlacement(20, 20, 100);

COM

ILCircleRegionPtr circleRoi = LCircleRegion::Create();
// or, ILCircleRegionPtr circleRoi(__uuidof(LCircleRegion)), for absence of built-in Create functions (before 2.2.0)
circleRoi->SetPlacement(20, 20, 100);

Member Function Documentation

SetPlacement()

void SetPlacement	(	double	cenx,
		double	ceny,
		double	r
	)

Modify the circle region's placement.

Parameters

[in]	cenx	The x-coordinate of the circle region center.
[in]	ceny	The y-coordinate of the circle region center.
[in]	r	Radius of the circle region.
