39 |* class GradientWrapper
41 |* Ersterstellung: KA 24.11.95
42 |* letzte Aenderung: KA 24.11.95
44 |* Zeck: dient beim MetaFile-Export dazu, die eigentliche Berechungs-
45 |* funktionalitaet zu kapseln. Das Schreiben der Records fuer
46 |* die unterschiedlichen File-Formate geschieht ueber LinkHandler.
48 |* Klassen, die diesen Wrapper benutzen, muessen drei Linkhandler
49 |* zur Verfuegung stellen, die im Ctor uebergeben werden:
51 |* 1. Linkhandler zum Schreiben eines Records fuer Polygonausgabe
52 |* 2. Linkhandler zum Schreiben eines Records fuer PolyPolygonausgabe
53 |* 3. Linkhandler zum Schreiben eines Records fuer Setzen der Brush
