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.- See Also:

Method Details
-
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
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.
