Interface PaintContext

public interface PaintContext

The PaintContext interface defines the encapsulated and optimized environment to generate color patterns in device space for fill or stroke operations on a Graphics2D. The PaintContext provides the necessary colors for Graphics2D operations in the form of a Raster associated with a ColorModel. The PaintContext maintains state for a particular paint operation. In a multi-threaded environment, several contexts can exist simultaneously for a single Paint object.

Method Summary

void	dispose() Releases the resources allocated for the operation.
ColorModel	getColorModel() Returns the ColorModel of the output.
Raster	getRaster(int x, int y, int w, int h) Returns a Raster containing the colors generated for the graphics operation.

Method Detail

dispose

public void dispose()

Releases the resources allocated for the operation.

getColorModel

public ColorModel getColorModel()

Returns the ColorModel of the output. Note that this ColorModel might be different from the hint specified in the createContext method of Paint. Not all PaintContext objects are capable of generating color patterns in an arbitrary ColorModel.

Returns:

the ColorModel of the output.

getRaster

public Raster getRaster(int x,
                        int y,
                        int w,
                        int h)

Returns a Raster containing the colors generated for the graphics operation.

Parameters:

w - the width of the area in device space

h - the height of the area in device space

Returns:

a Raster representing the specified rectangular area and containing the colors generated for the graphics operation.
