Method Details

arcTo

public void arcTo(double rx,
 double ry,
 double xAxisRotation,
 double x,
 double y,
 boolean largeArcFlag,
 boolean sweepFlag)

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.

As specified in w3.org

Parameters:

rx - the x radius of the ellipse

ry - the y radius of the ellipse

xAxisRotation - the angle from the x-axis of the current coordinate system to the x-axis of the ellipse in degrees.

x - the absolute x coordinate of the final point of the arc.

y - the absolute y coordinate of the final point of the arc.

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 chosen

sweepFlag - the sweep flag. If true the line joining center to arc sweeps through decreasing angles otherwise it sweeps through increasing angles
