Package org.apache.batik.ext.awt.geom
Class ExtendedGeneralPath
java.lang.Object
org.apache.batik.ext.awt.geom.ExtendedGeneralPath
- All Implemented Interfaces:
Shape
,Cloneable
,ExtendedShape
The
ExtendedGeneralPath
class represents a geometric
path constructed from straight lines, quadratic and cubic (Bezier)
curves and elliptical arc. This class delegates lines and curves to
an enclosed GeneralPath
. Elliptical arc is implemented
using an Arc2D
in float precision.
Warning : An elliptical arc may be composed of several path segments. For futher details, see the SVG Appendix F.6

Method Details

arcTo
public void arcTo(float rx, float ry, float angle, boolean largeArcFlag, boolean sweepFlag, float x, float y) Adds an elliptical arc, defined by two radii, an angle from the x-axis, a flag to choose the large arc or not, a flag to indicate if we increase or decrease the angles and the final point of the arc.- Parameters:
rx
- the x radius of the ellipsery
- the y radius of the ellipseangle
- the angle from the x-axis of the current coordinate system to the x-axis of the ellipse in degrees.largeArcFlag
- the large arc flag. If true the arc spanning less than or equal to 180 degrees is chosen, otherwise the arc spanning greater than 180 degrees is chosensweepFlag
- the sweep flag. If true the line joining center to arc sweeps through decreasing angles otherwise it sweeps through increasing anglesx
- the absolute x coordinate of the final point of the arc.y
- the absolute y coordinate of the final point of the arc.
-
computeArc
public static Arc2D computeArc(double x0, double y0, double rx, double ry, double angle, boolean largeArcFlag, boolean sweepFlag, double x, double y) This constructs an unrotated Arc2D from the SVG specification of an Elliptical arc. To get the final arc you need to apply a rotation transform such as: AffineTransform.getRotateInstance (angle, arc.getX()+arc.getWidth()/2, arc.getY()+arc.getHeight()/2); -

makeRoom
private void makeRoom(int numValues) Make sure, that the requested number of slots in vales[] are available. Must be called even for numValues = 0, because it is also used for initialization of those arrays.- Parameters:
numValues
- number of requested coordinates
