Interface Composite
- All Known Implementing Classes:
- AlphaComposite
public interface Composite
The 
Composite interface, along with
 CompositeContext, defines the methods to compose a draw
 primitive with the underlying graphics area.
 After the Composite is set in the
 Graphics2D context, it combines a shape, text, or an image
 being rendered with the colors that have already been rendered
 according to pre-defined rules. The classes
 implementing this interface provide the rules and a method to create
 the context for a particular operation.
 CompositeContext is an environment used by the
 compositing operation, which is created by the Graphics2D
 prior to the start of the operation.  CompositeContext
 contains private information and resources needed for a compositing
 operation.  When the CompositeContext is no longer needed,
 the Graphics2D object disposes of it in order to reclaim
 resources allocated for the operation.
 
 Instances of classes implementing Composite must be
 immutable because the Graphics2D does not clone
 these objects when they are set as an attribute with the
 setComposite method or when the Graphics2D
 object is cloned.  This is to avoid undefined rendering behavior of
 Graphics2D, resulting from the modification of
 the Composite object after it has been set in the
 Graphics2D context.

Method Details- 
createContextCompositeContext createContext(ColorModel srcColorModel, ColorModel dstColorModel, RenderingHints hints) Creates a context containing state that is used to perform the compositing operation. In a multi-threaded environment, several contexts can exist simultaneously for a singleCompositeobject.- Parameters:
- srcColorModel- the- ColorModelof the source
- dstColorModel- the- ColorModelof the destination
- hints- the hint that the context object uses to choose between rendering alternatives
- Returns:
- the CompositeContextobject used to perform the compositing operation.
