Class RasterGraphics

Implemented Interfaces:
Cloneable, Pixelizer

public class RasterGraphics
extends AbstractGraphics2D

A Graphics2D implementation that operates on Raster objects. This is primarily used for BufferedImages, but can theoretically be used on arbitrary WritableRasters.

Constructor Details

RasterGraphics

public RasterGraphics(WritableRaster r,
                      ColorModel cm)

Method Details

Rectangle getDeviceBounds

protected @Override Rectangle getDeviceBounds()

getColorModel

protected ColorModel getColorModel()
Returns the color model of this Graphics object.
Overrides:
getColorModel in interface AbstractGraphics2D
Returns:
the color model of this Graphics object

getDestinationRaster

protected WritableRaster getDestinationRaster()
Returns a WritableRaster that is used by this class to perform the rendering in. It is not necessary that the target surface immediately reflects changes in the raster. Updates to the raster are notified via AbstractGraphics2D.updateRaster(Raster,int,int,int,int).
Overrides:
getDestinationRaster in interface AbstractGraphics2D
Returns:
the destination raster

getDeviceConfiguration

public GraphicsConfiguration getDeviceConfiguration()
Overrides:
getDeviceConfiguration in interface Graphics2D

void renderScanline

public @Override void renderScanline(int y,
                                     ScanlineCoverage c)
