Interface Composite

Known Implementing Classes:
AlphaComposite, BitwiseXORComposite

public interface Composite

This interface is for graphics which are formed as composites of others. It combines Graphics2D shapes according to defined rules to form the new image. Implementations of this interface must be immutable, because they are not cloned when a Graphics2D container is cloned.

Since this can expose pixels to untrusted code, there is a security check on custom objects, readDisplayPixels, to prevent leaking restricted information graphically.

Method Summary

createContext(ColorModel srcColorModel, ColorModel dstColorModel, RenderingHints hints)
Create a context state for performing the compositing operation.

Method Details


public CompositeContext createContext(ColorModel srcColorModel,
                                      ColorModel dstColorModel,
                                      RenderingHints hints)
Create a context state for performing the compositing operation. Several contexts may exist for this object, in a multi-threaded environment.
srcColorModel - the color model of the source
dstColorModel - the color model of the destination
hints - hints for choosing between rendering alternatives -- graphics formed from composite layers Copyright (C) 2002, 2005 Free Software Foundation, Inc. This file is part of GNU Classpath.
