Class EllipticalCurveTo

java.lang.Object

com.itextpdf.svg.renderers.path.impl.AbstractPathShape

com.itextpdf.svg.renderers.path.impl.EllipticalCurveTo

All Implemented Interfaces:

IPathShape

public class EllipticalCurveTo
extends AbstractPathShape

Implements elliptical curveTo (A) segment of SVG's path element. Implemented in PDF as Bézier curves. Edge cases & value correction below always refer to https://www.w3.org/TR/SVG11/implnote.html#ArcImplementationNotes For some calculations we need double precision floating point math, so we have forced all calculations to use double. However, float comparison is used instead of double comparison, because close coordinates can be considered equal.

Constructor Detail

EllipticalCurveTo

public EllipticalCurveTo()

Creates an absolute Elliptical curveTo.

EllipticalCurveTo

public EllipticalCurveTo(boolean relative)

Creates a Elliptical curveTo. Set argument to true to create a relative EllipticalCurveTo.

Parameters:

relative - whether this is a relative EllipticalCurveTo or not

Method Detail

setCoordinates

public void setCoordinates(String[] inputCoordinates,
                           Point previous)

Description copied from interface: IPathShape

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

Parameters:

inputCoordinates - an array containing point values for path coordinates

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

draw

public void draw(PdfCanvas canvas)

Description copied from interface: IPathShape

Draws this instruction to a canvas object.

Parameters:

canvas - to which this instruction is drawn

getPathShapeRectangle

public Rectangle getPathShapeRectangle(Point lastPoint)

Description copied from class: AbstractPathShape

Get bounding rectangle of the current path shape.

Overrides:

getPathShapeRectangle in class AbstractPathShape

Parameters:

lastPoint - start point for this shape

Returns:

calculated rectangle
