- All Implemented Interfaces:
- Filter, GraphicsNodeRable, java.awt.image.renderable.RenderableImage
- public class ConcreteGraphicsNodeRable
- extends AbstractRable
- implements GraphicsNodeRable
This implementation of RenderableImage will render its input
GraphicsNode into a BufferedImage upon invokation of one of its
createRendering methods.

ConcreteGraphicsNodeRable
public ConcreteGraphicsNodeRable(GraphicsNode node)
- Parameters:
node
- The GraphicsNode this image should represent
ConcreteGraphicsNodeRable
public ConcreteGraphicsNodeRable(GraphicsNode node,
boolean usePrimitivePaint)
- Parameters:
node
- the GraphicsNode this image should representusePrimitivePaint
- indicates if the image should
include any filters or mask operations on node
getUsePrimitivePaint
public boolean getUsePrimitivePaint()
- Returns true if this Rable get's it's contents by calling
primitivePaint on the associated GraphicsNode or
false if it uses paint.
- Specified by:
getUsePrimitivePaint
in interface GraphicsNodeRable
setUsePrimitivePaint
public void setUsePrimitivePaint(boolean usePrimitivePaint)
- Set to true if this Rable should get it's contents by calling
primitivePaint on the associated GraphicsNode or false
if it should use paint.
- Specified by:
setUsePrimitivePaint
in interface GraphicsNodeRable
getGraphicsNode
public GraphicsNode getGraphicsNode()
- Returns the GraphicsNode rendered by this image
- Specified by:
getGraphicsNode
in interface GraphicsNodeRable
- Following copied from interface:
org.apache.batik.gvt.filter.GraphicsNodeRable
- Returns:
- the GraphicsNode associated with this image.
setGraphicsNode
public void setGraphicsNode(GraphicsNode node)
- Sets the GraphicsNode this image should render
- Specified by:
setGraphicsNode
in interface GraphicsNodeRable
getBounds2D
public java.awt.geom.Rectangle2D getBounds2D()
- Returns the bounds of this Rable in the user coordinate system.
- Specified by:
getBounds2D
in interface Filter
- Overrides:
getBounds2D
in class AbstractRable
isDynamic
public boolean isDynamic()
- Returns true if successive renderings (that is, calls to
createRendering() or createScaledRendering()) with the same arguments
may produce different results. This method may be used to
determine whether an existing rendering may be cached and
reused. It is always safe to return true.
- Specified by:
isDynamic
in interface java.awt.image.renderable.RenderableImage
- Overrides:
isDynamic
in class AbstractRable
createRendering
public java.awt.image.RenderedImage createRendering(java.awt.image.renderable.RenderContext renderContext)
- Creates a RenderedImage that represented a rendering of this image
using a given RenderContext. This is the most general way to obtain a
rendering of a RenderableImage.
The created RenderedImage may have a property identified
by the String HINTS_OBSERVED to indicate which RenderingHints
(from the RenderContext) were used to create the image.
In addition any RenderedImages
that are obtained via the getSources() method on the created
RenderedImage may have such a property.
- Specified by:
createRendering
in interface java.awt.image.renderable.RenderableImage
- Parameters:
renderContext
- the RenderContext to use to produce the rendering.- Returns:
- a RenderedImage containing the rendered data.
