public interface Paint extends Transparency
Paint interface defines how color patterns can be generated for
Graphics2D operations. A class implementing the
Paint interface is added to the
Graphics2D context in order to define the color pattern used by the
draw and
fill methods.
Instances of classes implementing Paint must be read-only because the Graphics2D does not clone these objects when they are set as an attribute with the setPaint method or when the Graphics2D object is itself cloned.

getTransparencyPaintContextcreateContext(ColorModel cm, Rectangle deviceBounds, Rectangle2D userBounds, AffineTransform xform, RenderingHints hints)
PaintContext used to generate the color pattern. The arguments to this method convey additional information about the rendering operation that may be used or ignored on various implementations of the
Paint interface. A caller must pass non-
null values for all of the arguments except for the
ColorModel argument which may be
null to indicate that no specific
ColorModel type is preferred. Implementations of the
Paint interface are allowed to use or ignore any of the arguments as makes sense for their function, and are not constrained to use the specified
ColorModel for the returned
PaintContext, even if it is not
null. Implementations are allowed to throw
NullPointerException for any
null argument other than the
ColorModel argument, but are not required to do so.
cm - the preferred
ColorModel which represents the most convenient format for the caller to receive the pixel data, or
null if there is no preference.
deviceBounds - the device space bounding box of the graphics primitive being rendered. Implementations of the
Paint interface are allowed to throw
NullPointerException for a
null
deviceBounds.
userBounds - the user space bounding box of the graphics primitive being rendered. Implementations of the
Paint interface are allowed to throw
NullPointerException for a
null
userBounds.
xform - the
AffineTransform from user space into device space. Implementations of the
Paint interface are allowed to throw
NullPointerException for a
null
xform.
hints - the set of hints that the context object can use to choose between rendering alternatives. Implementations of the
Paint interface are allowed to throw
NullPointerException for a
null
hints.
