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.

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
- theWritableRaster
into which the result of the operation is stored - See Also:
