Interface IGraphicsContext

All Known Implementing Classes:
CwtAwtGraphicsContext, CwtSwtGraphicsContext
public interface IGraphicsContext
A platform independent (SWT, AWT) description of a graphics context.

The primary goal of this one is derived from the requirements enforced by processing a PDF context stream.
