Interface PaintContext
-
public interface PaintContextThePaintContextinterface defines the encapsulated and optimized environment to generate color patterns in device space for fill or stroke operations on aGraphics2D. ThePaintContextprovides the necessary colors forGraphics2Doperations in the form of aRasterassociated with aColorModel. ThePaintContextmaintains state for a particular paint operation. In a multi-threaded environment, several contexts can exist simultaneously for a singlePaintobject.- See Also:

Method Detail
dispose
void dispose()
Releases the resources allocated for the operation.
getColorModel
ColorModel getColorModel()
Returns theColorModelof the output. Note that thisColorModelmight be different from the hint specified in thecreateContextmethod ofPaint. Not allPaintContextobjects are capable of generating color patterns in an arbitraryColorModel.- Returns:
-
the
ColorModelof the output.
getRaster
Raster getRaster(int x, int y, int w, int h)
Returns aRastercontaining 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 - Returns:
-
a
Rasterrepresenting the specified rectangular area and containing the colors generated for the graphics operation.
