3D Diagramm

RotationX-, RotationY- und DepthPercents-Eigenschaften des 3D-Diagramms setzen

Aspose.Slides für C++ bietet eine einfache API zum Setzen dieser Eigenschaften. Der folgende Artikel hilft Ihnen, wie Sie verschiedene Eigenschaften wie X, Y Rotation, DepthPercents usw. festlegen können. Der Beispielcode zeigt, wie man die oben genannten Eigenschaften setzt.

1. Erstellen Sie eine Instanz der Presentation Klasse.
2. Greifen Sie auf die erste Folie zu.
3. Fügen Sie ein Diagramm mit Standarddaten hinzu.
4. Setzen Sie die Rotation3D-Eigenschaften.
5. Schreiben Sie die geänderte Präsentation in eine PPTX-Datei.
