Constructor Details

BezierCurve

public BezierCurve(Shape.Point from,
 Shape.Point to,
 Shape.Point controlPoint)

Construct a quadratic Bezier curve.

Parameters:

from - Point from.

to - Point to.

controlPoint - Control point.

BezierCurve

public BezierCurve(Shape.Point from,
 Shape.Point to,
 Shape.Point controlPoint1,
 Shape.Point controlPoint2)

Construct a cubic Bezier curve.

Parameters:

from - Point from.

to - Point to.

controlPoint1 - First control point.

controlPoint2 - Second control point.

Method Details

getType

protected final String getType()

Description copied from class: Shape

Get the type of this shape.

Specified by:

getType in class Shape

Returns:

Type of the shape.

encodeJSON

public void encodeJSON(StringBuilder sb)

Description copied from interface: ComponentProperty

Encode the JSON string with the properties of this.

Specified by:

encodeJSON in interface ComponentProperty

Overrides:

encodeJSON in class Shape

Parameters:

sb - Encoded JSON string to be appended to this.

getFrom

public final Shape.Point getFrom()

Get the "from" point.

Returns:

From point.

setFrom

public void setFrom(Shape.Point from)

Set the "from" point.

Parameters:

from - From point.

getTo

public final Shape.Point getTo()

Get the "to" point.

Returns:

To point.

setTo

public void setTo(Shape.Point to)

Set the "to" point.

Parameters:

to - To point.

getControlPoint1

public final Shape.Point getControlPoint1()

Get the first control point for the cubic Bezier curve.

Returns:

First control point.

setControlPoint1

public void setControlPoint1(Shape.Point controlPoint)

Set the first control point for the cubic Bezier curve.

Parameters:

controlPoint - First control point.

getControlPoint2

public final Shape.Point getControlPoint2()

Get the second control point for the cubic Bezier curve.

Returns:

Second control point.

setControlPoint2

public void setControlPoint2(Shape.Point controlPoint)

Set the second control point for the cubic Bezier curve. If this is set to null, the curve will become quadratic.

Parameters:

controlPoint - Second control point.

getControlPoint

public final Shape.Point getControlPoint()

Get the control point for the quadratic Bezier curve.

Returns:

Control point.

setControlPoint

public void setControlPoint(Shape.Point controlPoint)

Set the control point for the quadratic Bezier curve. If this is set to null, the curve will become a straight line.

Parameters:

controlPoint - Second control point.
