OdPrcEllipse2d Class

Class Hierarchy

Syntax

C++

class OdPrcEllipse2d : public OdPrcCurve2d;

File

PrcEllipse2d.h

Description

Class implements a two-dimensional ellipse with its possible parameterization and transformation for positioning in model space.

Remarks

Transformation can be one of the following:

Value Description

0x00 Identity

0x01 Translate

0x02 Rotate

0x08 Scale

OdPrcEllipse2d inherits the OdPrcCurve class and can be reparameterized and trimmed using the OdPrcParameterization class and setParameterization() method.

OdPrcCurve Methods

	Name	Description
	contentCurve	This is the overview for the contentCurve method overload.
	is3d	Returns the current curve's 3D flag value. The flag is equal to true if the curve is a 3D object or is equal to false in the other case.
	parameterization	Returns the current parameterization information used for the curve.
	read	Reads curve data from a specified input stream, and creates and returns a curve entity.
	readArray	Reads data from a specified input stream into a curve array.
	readPtr	Reads curve data from a specified input stream, creates a curve, and returns a smart pointer to an OdPrcCurve object.
	setParameterization	Sets new parametrization information to the curve.
	writeArray	Writes data from a curve array to a specified output stream.
	writePtr	Writes curve data to a specified output stream.

OdPrcCurve2d Class

	Name	Description
	createFromOdGeCurve	Creates new 2d curve instance from OdGeCurve2d.
	getGeMatrix2d	Returns the current transformation matrix for the curve.
	getOdGeCurve	Returns the current curve data.
	is3d	Returns the current curve's 3D flag value. The flag is equal to true if the curve is a 3D object or is equal to false in the other case.
	setFromOdGeCurve	Sets a new instance of the curve data.
	setTransformation	Sets a new transformation for the curve.
	transformation	Returns the current transformation for the curve.

OdPrcEllipse2d Class

	Name	Description
	radiusAtXAxis	Returns the current ellipse X-axis radius value.
	radiusAtYAxis	Returns the current ellipse Y-axis radius value.
	setRadiusAtXAxis	Sets a new value of the ellipse radius at the X-axis.
	setRadiusAtYAxis	Sets a new value of the ellipse radius at the Y-axis.
