Trail: 2D Graphics

Lesson: Overview of the Java 2D API

The Java 2D API introduced in JDK 1.2 provides enhanced two-dimensional graphics, text, and imaging capabilities for Java programs through extensions to the Abstract Windowing Toolkit (AWT). This comprehensive rendering package supports line art, text, and images in a flexible, full-featured framework for developing richer user interfaces, sophisticated drawing programs and image editors.
The Java 2D API provides

A uniform rendering model for display devices and printers
A wide range of geometric primitives, such as curves, rectangles, and ellipses and a mechanism for rendering virtually any geometric shape
Mechanisms for performing hit detection on shapes, text, and images
A compositing model that provides control over how overlapping objects are rendered
Enhanced color support that facilitates color management
Support for printing complex documents

These topics are discussed in the following sections:
