PaintContext JDK 1.6)

Description

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 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.

Methods

Hide/Show inherited methods

public void dispose ()

Releases the resources allocated for the operation.

public ColorModel getColorModel ()

Returns the ColorModel of the output.

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.

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

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

Returns a Raster containing the colors generated for
the graphics operation.
Returns: a Raster representing the specified rectangular area and containing the colors generated for the graphics operation.
Parameters:
- x - the x coordinate of the area in device space for which colors are generated.
- y - the y coordinate of the area in device space for which colors are generated.
- w - the width of the area in device space
- h - the height of the area in device space
