ContextualRenderedImageFactory provides an interface for the functionality that may differ between instances of RenderableImageOp. Thus different operations on RenderableImages may be performed by a single class such as RenderedImageOp through the use of multiple instances of ContextualRenderedImageFactory. The name ContextualRenderedImageFactory is commonly shortened to "CRIF."
All operations that are to be used in a rendering-independent chain must implement ContextualRenderedImageFactory.
Classes that implement this interface must provide a constructor with no arguments.
Method Summary | |
RenderedImage |
create(RenderContext renderContext,
ParameterBlock paramBlock)
Creates a rendering, given a RenderContext and a ParameterBlock containing the operation's sources and parameters. |
Rectangle2D |
getBounds2D(ParameterBlock paramBlock)
Returns the bounding box for the output of the operation, performed on a given set of sources, in rendering-independent space. |
Object |
getProperty(ParameterBlock paramBlock,
String name)
Gets the appropriate instance of the property specified by the name parameter. |
String[] |
getPropertyNames()
Returns a list of names recognized by getProperty. |
boolean |
isDynamic()
Returns true if successive renderings (that is, calls to create(RenderContext, ParameterBlock)) with the same arguments may produce different results. |
RenderContext |
mapRenderContext(int i,
RenderContext renderContext,
ParameterBlock paramBlock,
RenderableImage image)
Maps the operation's output RenderContext into a RenderContext for each of the operation's sources. |
