Method Detail
-
getUsePrimitivePaint
public boolean getUsePrimitivePaint()
Returns true if this Rable get's it's contents by calling primitivePaint on the associatedGraphicsNode
or false if it uses paint.- Specified by:
getUsePrimitivePaint
in interfaceGraphicsNodeRable
-
setUsePrimitivePaint
public void setUsePrimitivePaint(boolean usePrimitivePaint)
Set to true if this Rable should get it's contents by calling primitivePaint on the associatedGraphicsNode
or false if it should use paint.- Specified by:
setUsePrimitivePaint
in interfaceGraphicsNodeRable
-
getGraphicsNode
public GraphicsNode getGraphicsNode()
Returns theGraphicsNode
rendered by this image- Specified by:
getGraphicsNode
in interfaceGraphicsNodeRable
- Returns:
- the
GraphicsNode
associated with this image.
-
setGraphicsNode
public void setGraphicsNode(GraphicsNode node)
Sets theGraphicsNode
this image should render- Specified by:
setGraphicsNode
in interfaceGraphicsNodeRable
-
clearCache
public void clearCache()
Clear any cached Red.
-
getBounds2D
public java.awt.geom.Rectangle2D getBounds2D()
Returns the bounds of this Rable in the user coordinate system.- Specified by:
getBounds2D
in interfaceFilter
- Overrides:
getBounds2D
in classAbstractRable
-
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 interfacejava.awt.image.renderable.RenderableImage
- Overrides:
isDynamic
in classAbstractRable
-
paintRable
public boolean paintRable(java.awt.Graphics2D g2d)
Should perform the equivilent action as createRendering followed by drawing the RenderedImage to Graphics2D, or return false.- Specified by:
paintRable
in interfacePaintRable
- 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 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 interfacejava.awt.image.renderable.RenderableImage
- Parameters:
renderContext
- the RenderContext to use to produce the rendering.- Returns:
- a RenderedImage containing the rendered data.
