3D 효과 및 시각 효과 작업 — Aspose.Slides FOSS for C++

Aspose.Slides FOSS for C++는 모든 도형에서 액세스할 수 있는 두 개의 별도 효과 시스템을 제공합니다:

  • EffectFormat (shape.effect_format()): 2D 시각 효과: 그림자, 빛남, 부드러운 가장자리, 흐림, 반사
  • ThreeDFormat (shape.three_d_format()): 3D 외관: 베벨, 카메라 투영, 라이트 리그, 재질, 압출 깊이

두 경우 모두 저장/재로드 사이클에서 지속됩니다.

시각 효과 (EffectFormat)

        ShapeType::RECTANGLE, 100, 100, 300, 120);
    shape.text_frame()->set_text("Shadowed Text");

    auto& ef = shape.effect_format();
    ef.enable_outer_shadow_effect();
    auto* shadow = ef.outer_shadow_effect();
    shadow->set_blur_radius(10);      // softness in points
    shadow->set_direction(315);       // angle: 315 = upper-left cast
    shadow->set_distance(8);          // offset in points
    shadow->shadow_color().set_color(Color::from_argb(128, 0, 0, 0));  // semi-transparent black

    pres.save("shadow.pptx", SaveFormat::PPTX);
    return 0;
}

공통 direction 값: 0 = 오른쪽, 45 = 오른쪽 아래, 90 = 아래, 270 = 위, 315 = 왼쪽 위.
