Class IntegerGraphicsState

Implemented Interfaces:
Cloneable
public class IntegerGraphicsState
extends AbstractGraphicsState
IntegerGraphicsState is one of several graphics state implementations. This graphics state is used when the graphics object has simple properties, (coordinate translation only, no transform) and the backend supports integer coordinates (pixel based). For primitive paint operations, this object translates the coordinates and forwards the request to the backend. For requests to draw arbitrary shapes and paths, this object translates the requests to primitive drawing operations supported by the backend. IntegerGraphicsState is meant to support the most common state of an graphics object. The degree of functionality is roughly equivalent with the old java.awt.Graphics API.

Nested Class Summary

static interface
IntegerGraphicsState.ScreenCoupledImage
Interface for images which are coupled to a GraphicsConfiguration, as is typically the case for an off-screen buffer used in double-buffering.
