Interface CompositeContext

public interface CompositeContext

The `CompositeContext` interface defines the encapsulated and optimized environment for a compositing operation. `CompositeContext` objects maintain state for compositing operations. In a multi-threaded environment, several contexts can exist simultaneously for a single `Composite` object.

See Also:
  `Composite`

Method Summary
`void` | `compose(Raster src, Raster dstIn, WritableRaster dstOut)` Composes the two source `Raster` objects and places the result in the destination `WritableRaster`.
`void` | `dispose()` Releases resources allocated for a context.

Method Detail

### dispose

    public void dispose()

  Releases resources allocated for a context.

### compose

    public void compose(Raster src,
                        Raster dstIn,
                        WritableRaster dstOut)

  Composes the two source `Raster` objects and places the result in the destination `WritableRaster`. Note that the destination can be the same object as either the first or second source. Note that `dstIn` and `dstOut` must be compatible with the `dstColorModel` passed to the `createContext` method of the `Composite` interface.

  Parameters:
    `src` - the first source for the compositing operation
    `dstIn` - the second source for the compositing operation
    `dstOut` - the `WritableRaster` into which the result of the operation is stored
