public interface PaintContext
ThePaintContext
interface defines the encapsulated and optimized environment to generate color patterns in device space for fill or stroke operations on aGraphics2D
. ThePaintContext
provides the necessary colors forGraphics2D
operations in the form of aRaster
associated with aColorModel
. ThePaintContext
maintains state for a particular paint operation. In a multi-threaded environment, several contexts can exist simultaneously for a singlePaint
object.- See Also:

Method Detail
-
dispose
void dispose()
Releases the resources allocated for the operation.
-
getColorModel
ColorModel getColorModel()
Returns theColorModel
of the output. Note that thisColorModel
might be different from the hint specified in thecreateContext
method ofPaint
. Not allPaintContext
objects are capable of generating color patterns in an arbitraryColorModel
.- Returns:
- the
ColorModel
of the output.

getRaster
Raster getRaster(int x, int y, int w, int h)
Returns aRaster
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 spaceh
- 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.
