Interface Paint

All Superinterfaces:
Transparency
Known Implementing Classes:
Color, ColorUIResource, GradientPaint, ImagePaint, SystemColor, TexturePaint
public interface Paint
extends Transparency
Defines how color patterns are generated for Graphics2D operations. This is used to perform the draw and fill methods of the graphics object. Instances must be immutable, because the graphics object does not clone them.
Since:
1.1
See Also:
PaintContext, Color, GradientPaint, TexturePaint, Graphics2D.setPaint(Paint)

Fields inherited from interface java.awt.Transparency

Method Summary

PaintContext
createContext(ColorModel cm, Rectangle deviceBounds, Rectangle2D userBounds, AffineTransform xform, RenderingHints hints)
Create the context necessary for performing the color pattern generation.

Method Details

createContext

public PaintContext createContext(ColorModel cm,
                                  Rectangle deviceBounds,
                                  Rectangle2D userBounds,
                                  AffineTransform xform,
                                  RenderingHints hints)
Create the context necessary for performing the color pattern generation. The color model is a hint, and may be null for Classpath implementations; however some legacy code may throw a NullPointerException when passed a null. Leaving the color model null provides the most efficiency and leeway in the generation of the color pattern.
Parameters:
cm - the color model, used as a hint
deviceBounds - the device space bounding box of the painted area
userBounds - the user space bounding box of the painted area
xform - the transformation from user space to device space
hints - any hints for choosing between rendering alternatives
Returns:
the context for performing the paint
