```
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.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`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
```
void dispose()
```
    Releases resources allocated for a context.
  - compose
```
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
