Properties
double	CenterX [get, set]
	The x-coordinate of the annulus region center.
double	CenterY [get, set]
	The y-coordinate of the annulus region center.
double	InnerRadius [get, set]
	The inner radius of the annulus region.
double	OuterRadius [get, set]
	The outer radius of the annulus 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 an annulus region object.

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

Example Code

C++

ILAnnulusRegionPtr annulusRoi = LAnnulusRegion::Create();
annulusRoi->SetPlacement(20, 20, 100, 200);

C#

LAnnulusRegion annulusRoi = new LAnnulusRegion();
annulusRoi.SetPlacement(20, 20, 100, 200);

COM

ILAnnulusRegionPtr annulusRoi = LAnnulusRegion::Create();
// or, ILAnnulusRegionPtr annulusRoi(__uuidof(LAnnulusRegion)), for absence of built-in Create functions (before 2.2.0)
annulusRoi->SetPlacement(20, 20, 100, 200);

Member Function Documentation

SetPlacement()

void SetPlacement	(	double	cenx,
		double	ceny,
		double	rInner,
		double	rOuter
	)

Modify the annulus region's placement.

Parameters

[in]	cenx	The x-coordinate of the annulus region center.
[in]	ceny	The y-coordinate of the annulus region center.
[in]	rInner	Inner radius of the annulus region.
[in]	rOuter	Outer radius of the annulus region.
