All Implemented Interfaces:
RenderableImage, Filter, PaintRable, GraphicsNodeRable
public class GraphicsNodeRable8Bit extends AbstractRable implements GraphicsNodeRable, PaintRable
This implementation of RenderableImage will render its input GraphicsNode into a BufferedImage upon invokation of one of its createRendering methods.

    • GraphicsNodeRable8Bit

      public GraphicsNodeRable8Bit(GraphicsNode node, boolean usePrimitivePaint)
      Parameters:
      node - the GraphicsNode this image should represent
      usePrimitivePaint - indicates if the image should include any filters or mask operations on node

  • Method Details

    • 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
      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

    • clearCache

      public void clearCache()
      Clear any cached Red.

    • getBounds2D

      public 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 RenderableImage
      Overrides:
      isDynamic in class AbstractRable

    • paintRable

      public boolean paintRable(Graphics2D g2d)
      Should perform the equivilent action as createRendering followed by drawing the RenderedImage to Graphics2D, or return false.
      Specified by:
      paintRable in interface PaintRable
      Parameters:
      g2d - The Graphics2D to draw to.
      Returns:
      true if the paint call succeeded, false if for some reason the paint failed (in which case a createRendering should be used).

    • createRendering

      public RenderedImage createRendering(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 RenderableImage
      Parameters:
      renderContext - the RenderContext to use to produce the rendering.
      Returns:
      a RenderedImage containing the rendered data.
