public interface Renderer
Interface for GVT Renderers.
Method Summary | |
---|---|
void |
dispose()
Cause the renderer to ask to be removed from external reference lists, de-register as a listener to events, etc. |
java.awt.geom.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 |
GraphicsNode |
getTree()
Returns the GVT tree associated with this renderer |
boolean |
isDoubleBuffered()
Returns true if the Renderer is currently doubleBuffering is rendering requests. |
void |
repaint(RectListManager areas)
Repaints the associated GVT tree at least in areas under the list of areas. |
void |
repaint(java.awt.Shape area)
Repaints the associated GVT tree at least under area. |
void |
setDoubleBuffered(boolean isDoubleBuffered)
Turns on/off double buffering in renderer. |
void |
setTransform(java.awt.geom.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. |
void |
setTree(GraphicsNode treeRoot)
This associates the given GVT Tree with this renderer. |
