Interface TransformableFigure

public interface TransformableFigure extends TransformCachingFigure, Figure
A transformable figure supports the transformation of a figure.

The following transformations are supported:

  • Translation of the local bounds of the figure.
  • Rotation around the center of the untransformed local bounds of the figure.
  • Scaling around the center of the untransformed local bounds of the figure.
  • Arbitrary sequence of affine transformations of the figure.
Note that transformation matrices computed from the Rotation and Scaling must be recomputed every time when the local bounds of the figure change.

    • applyTransformableFigureProperties

      default void applyTransformableFigureProperties(RenderContext ctx, javafx.scene.Node node)
      Updates a figure node with all transformation properties defined in this interface.

      Applies the following properties: TRANSFORM, translation TRANSLATE_X, TRANSLATE_Y, TRANSLATE_Z, scale SCALE_X, SCALE_Y, SCALE_Z, and rotation ROTATE, ROTATION_AXIS.

      Parameters:
      ctx - the render context
      node - a node which was created with method Figure.createNode(org.jhotdraw8.draw.render.RenderContext).
