Examples of ae.java.awt.PaintContext

ae.java.awt.PaintContext
The PaintContext interface defines the encapsulated and optimized environment to generate color patterns in device space for fill or stroke operations on a {@link Graphics2D}. The PaintContext provides the necessary colors for Graphics2D operations in the form of a {@link Raster} associated with a {@link ColorModel}. The PaintContext maintains state for a particular paint operation. In a multi-threaded environment, several contexts can exist simultaneously for a single {@link Paint} object. @see Paint
