2.1 Interfaces and Classes

The following tables list the interfaces and classes used in conjunction with the Graphics2D context, including the classes that represent state attributes. Most of these classes are part of the java.awt package.

Interface	Description
Composite	Defines methods to compose a draw primitive with the underlying graphics area. Implemented by AlphaComposite.
CompositeContext	Defines the encapsulated and optimized environment for a composite operation. Used by programmers implementing custom compositing rules.
Paint	Extends: Transparency Defines colors for a draw or fill operation. Implemented by Color, GradientPaint and TexturePaint.
PaintContext	Defines the encapsulated and optimized environment for a paint operation. Used by programmers implementing custom paint operations.
Stroke	Generates a Shape that encloses the outline of the Shape to be rendered. Implemented by BasicStroke.

Class	Description
AffineTransform (java.awt.geom)	Represents a 2D affine transform, which performs a linear mapping from 2D coordinates to other 2D coordinates.
AlphaComposite	Implements: Composite Implements basic alpha composite rules for shapes, text, and images.
BasicStroke	Implements: Stroke Defines the "pen style" to be applied to the outline of a Shape.
Color	Implements: Paint Defines a solid color fill for a Shape.
GradientPaint	Implements: Paint Defines a linear color gradient fill pattern for a Shape. This fill pattern changes from color C1 at point P1 to color C2 at point P2.
Graphics2D	Extends: Graphics Fundamental class for 2D rendering. Extends the original java.awt.Graphics class.
TexturePaint	Implements: Paint Defines a texture or pattern fill for a Shape. The texture or pattern is generated from a BufferedImage.
