3D チャートの RotationX、RotationY、および DepthPercents プロパティを設定する
Aspose.Slides for C++ は、これらのプロパティを設定するためのシンプルな API を提供します。以下の記事では、X、Y 回転、DepthPercents などの異なるプロパティを設定する方法について説明します。サンプルコードでは、上記のプロパティを設定しています。
- Presentation クラスのインスタンスを作成します。
- 最初のスライドにアクセスします。
- デフォルトデータでチャートを追加します。
- Rotation3D プロパティを設定します。
- 修正されたプレゼンテーションを PPTX ファイルに書き込みます。
