Interface Paint
- Transparency
- Color, ColorUIResource, GradientPaint, SystemColor, TexturePaint
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.
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.
cm
- the color model, used as a hintdeviceBounds
- the device space bounding box of the painted areauserBounds
- the user space bounding box of the painted areaxform
- the transformation from user space to device spacehints
- any hints for choosing between rendering alternatives
- the context for performing the paint
