VectorGraphicsConstants

public class CGMGraphics2D

extends AbstractVectorGraphicsIO

Implementation of VectorGraphics that writes the output to a CGM file. Users of this class have to generate a TagWriter and create an instance by invoking the factory method or the constructor. Document specific settings like page size can then be made by the appropriate setter methods. Before starting to draw, startExport() must be called. When drawing is finished, call endExport().
