public class ArcTo extends PathElement
For more information on path elements see the Path
and
PathElement
classes.
Example:
import javafx.scene.shape.*; Path path = new Path(); MoveTo moveTo = new MoveTo(); moveTo.setX(0.0); moveTo.setY(0.0); ArcTo arcTo = new ArcTo(); arcTo.setX(50.0); arcTo.setY(50.0); arcTo.setRadiusX(50.0); arcTo.setRadiusY(50.0); path.getElements().add(moveTo); path.getElements().add(arcTo);
Following image demonstrates radiusX
, radiusY
and
xAxisRotation
parameters:
radiusX
is the horizontal radius of the full ellipse of which this arc is
a partial section, radiusY
is its vertical radius.
xAxisRotation
defines the rotation of the ellipse in degrees.
In most cases, there are four options of how to draw an arc from
starting point to given end coordinates. They can be distinguished by
largeArcFlag
and sweepFlag
parameters.
largeArcFlag == true
means that the arc greater than 180 degrees will
be drawn. sweepFlag == true
means that the arc will be drawn
in the positive angle direction - i.e. the angle in the
ellipse formula will increase from [fromX, fromY]
to [x,y]
.
Following images demonstrate this behavior:
