形状に3D効果と影を適用する方法

形状に3D効果と影を適用する方法

Aspose.Slides FOSS は、すべてのシェイプに対して 2 つの独立したエフェクト システムを提供します：

  • shape.getEffectFormat(): 2D ビジュアルエフェクト: 外側の影、発光、ぼかし、ソフトエッジ
  • shape.getThreeDFormat(): 3D 外観: ベベル、カメラパースペクティブ、ライトリグ、マテリアル、深度

両方のシステムは同じ形状で組み合わせることができます。

    );
    shape.addTextFrame("Shadowed Shape");

    IEffectFormat ef = shape.getEffectFormat();
    ef.enableOuterShadowEffect();
    ef.getOuterShadowEffect().setBlurRadius(10);       // softness in points
    ef.getOuterShadowEffect().setDirection(315);       // 315 degrees = upper-left
    ef.getOuterShadowEffect().setDistance(8);           // offset in points
