Class TexturePaintContext

Implemented Interfaces:
PaintContext
public class TexturePaintContext
extends Object
implements PaintContext
A PaintContext implementation for TexturePaint, done in pure Java.

Constructor Summary

TexturePaintContext(TexturePaint t, Rectangle db, Rectangle2D ub, AffineTransform xform)
Creates a new TexturePaintContext for the specified TexturePaint object.

Method Summary

void
dispose()
Disposes the PaintContext.
ColorModel
getColorModel()
Returns the color model of this PaintContext.
Raster
getRaster(int x1, int y1, int w, int h)
Returns the Raster that is used for painting.

Constructor Details

TexturePaintContext

public TexturePaintContext(TexturePaint t,
                           Rectangle db,
                           Rectangle2D ub,
                           AffineTransform xform)
Creates a new TexturePaintContext for the specified TexturePaint object. This initializes the Raster which is returned by getRaster(int,int,int,int).
Parameters:
t - the texture paint object
db - the bounds of the target raster in device space
ub - the bounds of the target raster in user space
xform - the transformation from user space to device space

Method Details

dispose

public void dispose()
Disposes the PaintContext. Nothing is to do here, since we don't use any native resources in that implementation.
Specified by:
dispose in interface PaintContext

getColorModel

public ColorModel getColorModel()
Returns the color model of this PaintContext. This implementation returnes the color model used by the BufferedImage in the TexturePaint object, this avoids costly color model transformations (at least at this point).
Specified by:
getColorModel in interface PaintContext
Returns:
the color model of this PaintContext

getRaster

public Raster getRaster(int x1,
                        int y1,
                        int w,
                        int h)
Returns the Raster that is used for painting.
Specified by:
getRaster in interface PaintContext
Parameters:
x1 - the x location of the raster inside the user bounds of this paint context
y1 - the y location of the raster inside the user bounds of this paint context
w - the width
h - the height
Returns:
the Raster that is used for painting
