Method Summary
Modifier and TypeMethodDescriptionvoid
dispose()
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 speakinggetTree()
Returns the GVT tree associated with this rendererboolean
Returns true if the Renderer is currently doubleBuffering is rendering requests.void
Repaints the associated GVT tree at least underarea
.void
repaint
(RectListManager areas) Repaints the associated GVT tree at least in areas under the list ofareas
.void
setDoubleBuffered
(boolean isDoubleBuffered) Turns on/off double buffering in renderer.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.void
setTree
(GraphicsNode treeRoot) This associates the given GVT Tree with this renderer.

Method Details
-
setTree
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
Repaints the associated GVT tree at least underarea
.- Parameters:
area
- the region to be repainted, in the current user space coordinate system.
-
repaint
Repaints the associated GVT tree at least in areas under the list ofareas
.- Parameters:
areas
- a List of regions to be repainted, in the current user space coordinate system.
-
setTransform
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.
