public class Rotate2D
- extends GRTransform2D
Rotate a two-dimensional figure based on the angle, and anchor point
provided by the user. The angle, step, and anchor points can either
be preset in the parameter edit window, or updated dynamically through
the actor's ports. The angle can be specified in radians or degrees
by selecting the angle type in the parameter edit window. Angles
increase clockwise beginning at the positive X-axis in a Cartesian
plane. If the accumulate parameter defined in the base class
is set to true, any changes to the angle of rotation will be relative
to the figure's current orientation. Otherwise, the angle specified
will be relative to the positive X-axis.
