In the preceding sections you have seen that the rendering process is quite complex. Although the Java 2D API is surprisingly fast in most cases, sometimes you would like to have control over trade-offs between speed and quality. You can achieve this by setting rendering hints. The
setRenderingHint method of the
Graphics2D class lets you set a single hint. The hints’ keys and values are declared in the
RenderingHints class. Table 7.2 summarizes the choices. The values that end in
_DEFAULT denote the defaults that are chosen by a particular implementation as a good trade-off between performance and quality.
The most useful of these settings involves antialiasing. This technique removes the “jaggies” ...
