Field Summary

protected int	alpha instance variable for the alpha value when writing a pixel
static java.awt.image.ColorModel	argbmodel constant that defines a ColorModel that do support alpha values
protected double	transparency instance variable for the transparency level in percent
protected int	txOrg instance variable for the origin translation in x direction
protected int	tyOrg instance variable for the origin translation in y direction
static java.awt.image.ColorModel	xrgbmodel constant that defines a ColorModel that do not support alpha values

Constructor Summary

AWTPatternPaintContext(Pattern pattern, java.awt.Rectangle rcPaint, int transparency)
Constructor that creates a AWTPatternPaintContext with the Pattern given by pattern, the transparency level given by transparency that renders within the Rectangle given by rcPaint.

Method Summary

void	dispose()
java.awt.image.ColorModel	getColorModel()
java.awt.image.Raster	getRaster(int x, int y, int w, int h)
void	setColorModel(boolean hasAlpha) Sets the ColorModel for the AWTPaintContext with respect to the flag given by hasAlpha that indicates whether the AWTPaintContext should support transparency or not.
