public interface PaintContext
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.Paint| Modifier and Type | Method and Description |
|---|---|
void |
dispose()
Releases the resources allocated for the operation.
|
ColorModel |
getColorModel()
Returns the
ColorModel of the output. |
Raster |
getRaster(int x,
int y,
int w,
int h)
Returns a
Raster containing the colors generated for
the graphics operation. |
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 spaceRaster representing the specified
rectangular area and containing the colors generated for
the graphics operation. Submit a bug or feature
