Paint (Java SE 19 & JDK 19)

All Superinterfaces:

Transparency

All Known Implementing Classes:

Color, ColorUIResource, GradientPaint, LinearGradientPaint, MultipleGradientPaint, RadialGradientPaint, SystemColor, TexturePaint

This

interface defines how color patterns can be generated for

operations. A class implementing the

interface is added to the

context in order to define the color pattern used by the

and

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.

• GradientPaint
• TexturePaint
• Graphics2D.setPaint(java.awt.Paint)

• Field Summary
• Method Summary

  Creates and returns a

  PaintContext

  used to generate the color pattern.

• Method Details
  • createContext

    Creates and returns a

    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.

    Parameters:

    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.

    Returns:

    the PaintContext for generating color patterns.
