Wie man 3D-Effekte und Schatten auf Formen anwendet

Aspose.Slides FOSS provides two independent effect systems on every shape:

  • shape.getEffectFormat(): 2D-Blickeffekte: äußerer Schatten, Glanz, Unschärfe und weiche Kanten
  • shape.getThreeDFormat():3D-Aussehen: Bevel, Kameraperspektive, Lichtgerät, Material und Tiefe

Beide Systeme können auf derselben Form kombiniert werden.

    );
    shape.getEffectFormat().setBlurEffect(10, true);

    prs.save("blur.pptx", SaveFormat.PPTX);
}

grow=true die Verwölbung über den Formgrenz hinaus erweitert; grow=false Klimmt die Unschärfe in der Form.

3D-Bell verwenden
