Properties
double	Angle [get, set]
	The angle of the rotated rectangle region.
double	CenterX [get, set]
	The x-coordinate of the region center.
double	CenterY [get, set]
	The y-coordinate of the region center.
double	Height [get, set]
	The height of the rotated rectangle region.
double	Width [get, set]
	The width of the rotated rectangle 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 rotated rectangle region object.

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

Example Code

C++

ILRotRectRegionPtr rrRoi = LRotRectRegion::Create();
rrRoi->SetPlacement(20, 20, 100, 50, 30); // 30 degree

C#

LRotRectRegion rrRoi = new LRotRectRegion();
rrRoi.SetPlacement(20, 20, 100, 50, 30); // 30 degree

COM

ILRotRectRegionPtr rrRoi = LRotRectRegion::Create();
// or, ILRotRectRegionPtr rrRoi(__uuidof(LRotRectRegion)), for absence of built-in Create functions (before 2.2.0)
rrRoi->SetPlacement(20, 20, 100, 50, 30); // 30 degree

Member Function Documentation

SetPlacement()

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

Modify the rotated rectangle region's placement.

Parameters

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