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.

void dispose()
ColorModel getColorModel()
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
.
ColorModel
of the output.Raster getRaster(int x, int y, int w, int h)
Raster
containing the colors generated for
the graphics operation.
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
Raster
representing the specified
rectangular area and containing the colors generated for
the graphics operation.
