Properties
double	Angle [get, set]
	The angle of the ellipse region, aka. the orientation of the long axis.
double	CenterX [get, set]
	The x-coordinate of the ellipse region's center.
double	CenterY [get, set]
	The y-coordinate of the ellipse region's center.
double	Height [get, set]
	The length of the ellipse region's minor axis.
double	Width [get, set]
	The length of the ellipse region's major axis.
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...
Properties inherited from ILObject
LString	Name [get, set]
	Name of the object. By default, the object has no name. In most cases, LPV classes don't make use of the names. The name is drawn on canvas around the object if ILDrawable::SetDrawName() is enabled. More...

Detailed Description

This interface expose APIs to create/modify an ellipse region object.

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

Example Code

C++

ILEllipseRegionPtr ellipseRoi = LEllipseRegion::Create();
annulusRoi->SetPlacement(200, 100, 50, 100, 15);

C#

LEllipseRegion annulusRoi = new LEllipseRegion();
annulusRoi.SetPlacement(200, 100, 50, 100, 15);

COM

ILEllipseRegionPtr ellipseRoi = LEllipseRegion::Create();
// or, ILEllipseRegionPtr ellipseRoi(__uuidof(LEllipseRegion)), for absence of built-in Create functions (before 2.2.0)
annulusRoi->SetPlacement(200, 100, 50, 100, 15);

Member Function Documentation

SetPlacement()

void SetPlacement	(	double	cenx,
		double	ceny,
		double	w,
		double	h,
		double	a
	)

Modify the ellipse region's placement.

Parameters

[in]	cenx	The x-coordinate of the ellipse region center.
[in]	ceny	The y-coordinate of the ellipse region center.
[in]	w	The width of the ellipse region.
[in]	h	The height of the ellipse region.
[in]	a	The angle of the ellipse region.
