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.

createContext |
Creates and returns a PaintContext used to generate the color pattern. |
getTransparency
PaintContext createContext(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
.PaintContext
for generating color patterns.
