  • Method Summary

    Modifier and Type
    Method
    Description
    void
    Cause the renderer to ask to be removed from external reference lists, de-register as a listener to events, etc.
    Returns a copy of the transform from the current user space (as defined by the top node of the GVT tree) to the device space (1 unit = 1/72nd of an inch / 1 pixel, roughly speaking
    Returns the GVT tree associated with this renderer
    boolean
    Returns true if the Renderer is currently doubleBuffering is rendering requests.
    void
    repaint(Shape area)
    Repaints the associated GVT tree at least under area.
    void
    Repaints the associated GVT tree at least in areas under the list of areas.
    void
    setDoubleBuffered(boolean isDoubleBuffered)
    Turns on/off double buffering in renderer.
    void
    Sets the transform from the current user space (as defined by the top node of the GVT tree, to the associated device space.
    void
    This associates the given GVT Tree with this renderer.
  • Method Details

    • setTree

      void setTree(GraphicsNode treeRoot)
      This associates the given GVT Tree with this renderer. Any previous tree association is forgotten. Not certain if this should be just GraphicsNode, or CanvasGraphicsNode.
    • getTree

      GraphicsNode getTree()
      Returns the GVT tree associated with this renderer
    • repaint

      void repaint(Shape area)
      Repaints the associated GVT tree at least under area.
      Parameters:
      area - the region to be repainted, in the current user space coordinate system.
    • repaint

      void repaint(RectListManager areas)
      Repaints the associated GVT tree at least in areas under the list of areas.
      Parameters:
      areas - a List of regions to be repainted, in the current user space coordinate system.
    • setTransform

      void setTransform(AffineTransform usr2dev)
      Sets the transform from the current user space (as defined by the top node of the GVT tree, to the associated device space.
    • getTransform

      AffineTransform getTransform()
      Returns a copy of the transform from the current user space (as defined by the top node of the GVT tree) to the device space (1 unit = 1/72nd of an inch / 1 pixel, roughly speaking
    • isDoubleBuffered

      boolean isDoubleBuffered()
      Returns true if the Renderer is currently doubleBuffering is rendering requests. If it is then getOffscreen will only return completed renderings (or null if nothing is available).
    • setDoubleBuffered

      void setDoubleBuffered(boolean isDoubleBuffered)
      Turns on/off double buffering in renderer. Turning off double buffering makes it possible to see the ongoing results of a render operation.
    • dispose

      void dispose()
      Cause the renderer to ask to be removed from external reference lists, de-register as a listener to events, etc. This is so that in the absence of other existing references, it can be removed by the garbage collector.
