Method Summary

Modifier and Type	Method and Description
void	draw() Draws a quadratic Bezier curve from the current point to (x,y) using (x1,y1) as the control point
com.itextpdf.kernel.geom.Point	getLastControlPoint() Returns coordinates of the last control point (the one closest to the ending point) in the Bezier curve, in SVG space coordinates
com.itextpdf.kernel.geom.Rectangle	getPathShapeRectangle(com.itextpdf.kernel.geom.Point lastPoint) Get bounding rectangle of the current path shape.
void	setCoordinates(String[] inputCoordinates, com.itextpdf.kernel.geom.Point startPoint) This method sets the coordinates for the path painting operator and does internal preprocessing, if necessary

Constructor Detail

QuadraticCurveTo

public QuadraticCurveTo()

Creates new QuadraticCurveTo instance.

QuadraticCurveTo

public QuadraticCurveTo(boolean relative)

Creates new QuadraticCurveTo instance.

Parameters:

relative - true in case it is a relative operator, false if it is an absolute operator

QuadraticCurveTo

public QuadraticCurveTo(boolean relative,
                        IOperatorConverter copier)

Creates new QuadraticCurveTo instance.

Parameters:

relative - true in case it is a relative operator, false if it is an absolute operator

copier - IOperatorConverter copier for converting relative coordinates to absolute coordinates

Method Detail

draw

public void draw()

Draws a quadratic Bezier curve from the current point to (x,y) using (x1,y1) as the control point

Specified by:

draw in class AbstractPathShape

setCoordinates

public void setCoordinates(String[] inputCoordinates,
                           com.itextpdf.kernel.geom.Point startPoint)

Description copied from interface: IPathShape

This method sets the coordinates for the path painting operator and does internal preprocessing, if necessary

Specified by:

setCoordinates in interface IPathShape

Parameters:

inputCoordinates - an array containing point values for path coordinates

startPoint - the ending point of the previous operator, or, in broader terms, the point that the coordinates should be absolutized against, for relative operators

getLastControlPoint

public com.itextpdf.kernel.geom.Point getLastControlPoint()

Description copied from interface: IControlPointCurve

Returns coordinates of the last control point (the one closest to the ending point) in the Bezier curve, in SVG space coordinates

Specified by:

getLastControlPoint in interface IControlPointCurve

Returns:

coordinates of the last control point in SVG space coordinates

getPathShapeRectangle

public com.itextpdf.kernel.geom.Rectangle getPathShapeRectangle(com.itextpdf.kernel.geom.Point lastPoint)

Description copied from class: AbstractPathShape

Get bounding rectangle of the current path shape.

Specified by:

getPathShapeRectangle in interface IPathShape

Overrides:

getPathShapeRectangle in class AbstractPathShape

Parameters:

lastPoint - start point for this shape

Returns:

calculated rectangle
