public class Scale2D

extends GRTransform2D

Scale a two-dimensional figure by the x and y factor provided by the user. If accumulate is set to true, any changes to the scale will be be relative to the figure's current size. Otherwise, the scaling factor specified will be relative to the original size of the figure.

Since:

VisualSim4.0

Constructor Detail

Scale2D

public Scale2D(VisualSim.kernel.CompositeEntity container,
               java.lang.String name)
        throws VisualSim.kernel.util.IllegalActionException,
               VisualSim.kernel.util.NameDuplicationException

Construct an actor with the given container and name.

Parameters:

container - The container.

name - The name of this actor.

Throws:

VisualSim.kernel.util.IllegalActionException - If the actor cannot be contained by the proposed container.

VisualSim.kernel.util.NameDuplicationException - If the container already has an actor with this name.

Method Detail

_applyInitialTransform

protected void _applyInitialTransform(diva.canvas.Figure figure)
                               throws VisualSim.kernel.util.IllegalActionException

Apply the initial scaling transformation to the figure.

Specified by:

_applyInitialTransform in class GRTransform2D

Parameters:

figure - The figure the transformation is to be applied to.

Throws:

VisualSim.kernel.util.IllegalActionException - If the getToken() method throws such an exception.

_applyTransform

protected void _applyTransform(diva.canvas.Figure figure)
                        throws VisualSim.kernel.util.IllegalActionException

Apply the current scaling transformation to the figure.

Specified by:

_applyTransform in class GRTransform2D

Parameters:

figure - The figure the transformation is to be applied to.

Throws:

VisualSim.kernel.util.IllegalActionException - If the getToken() method throws such an exception.
