public interface ILcdEllipse
extends ILcdShape

An ILcdEllipse is an ILcdShape that represents a general ellipse in the 2D space. The ellipse has a center, a semi-major axis with a rotation angle, and a semi-minor axis.

The parameters of the ellipse can only be read, not modified.

Field Summary

Fields

Modifier and Type	Field and Description
static int	MAJOR_RADIUS_CORNER Specifies the end point of the major radius axis (at the rotation angle).
static int	MAJOR_RADIUS_OPPOSITE_CORNER Specifies the end point of the major radius axis at the rotation angle (at the rotation angle + 180 degrees).
static int	MINOR_RADIUS_CORNER Specifies the corner point of the minor radius axis (at the rotation angle + 90 degrees).
static int	MINOR_RADIUS_OPPOSITE_CORNER Specifies the corner point of the minor radius axis (at the rotation angle - 90 degrees).

Method Summary

Modifier and Type	Method and Description
void	corner2DEditablePointSFCT(int aCorner, ILcd2DEditablePoint a2DEditablePointSFCT) Computes the position of the specified corner of this ILcdEllipse.
double	getA() Returns the length of the semi-major axis.
double	getB() Returns the length of the semi-minor axis.
ILcdPoint	getCenter() Returns the center of this ILcdEllipse.
double	getRotAngle() Returns the rotation angle of the major axis (in degrees).

Method Detail

getCenter

ILcdPoint getCenter()

Returns the center of this ILcdEllipse.

Returns:

the center of this ILcdEllipse.

getA

double getA()

Returns the length of the semi-major axis.

Returns:

the length of the semi-major axis.

getB

double getB()

Returns the length of the semi-minor axis.

Returns:

the length of the semi-minor axis.

getRotAngle

double getRotAngle()

Returns the rotation angle of the major axis (in degrees). The angle is measured from 3 o'clock position, positive counter-clockwise.

corner2DEditablePointSFCT

void corner2DEditablePointSFCT(int aCorner,
                               ILcd2DEditablePoint a2DEditablePointSFCT)

Computes the position of the specified corner of this ILcdEllipse.

Parameters:

aCorner - the corner: ILcdEllipse.MAJOR_RADIUS_CORNER, ILcdEllipse.MINOR_RADIUS_CORNER, ILcdEllipse.MAJOR_RADIUS_OPPOSITE_CORNER, ILcdEllipse.MINOR_RADIUS_OPPOSITE_CORNER.

a2DEditablePointSFCT - an ILcd2DEditablePoint into which the result is written as a side-effect.
