Efek visual di PowerPoint dengan C++ Fills, Shadows, Glow, 3D Bevel

Aspose.Slides FOSS for C++ lets you apply professional-quality visual effects to PowerPoint shapes in native C++, with no Microsoft Office and no API keys. This post demonstrates the fill system, 2D effects, and 3D formatting available in the library.

Sistem Pengisian

Setiap bentuk memiliki … fill_format() Empat jenis isian yang ditunjukkan di bawah ini mencakup inti dari palet desain PowerPoint.

Isian padat

Pengisian paling sederhana, warna datar dengan transparansi opsional:

#include <Aspose/Slides/Foss/auto_shape.h>
#include <Aspose/Slides/Foss/drawing/color.h>
#include <Aspose/Slides/Foss/export/save_format.h>
#include <Aspose/Slides/Foss/fill_format.h>
#include <Aspose/Slides/Foss/fill_type.h>
#include <Aspose/Slides/Foss/presentation.h>
#include <Aspose/Slides/Foss/shape_collection.h>
#include <Aspose/Slides/Foss/shape_type.h>
#include <Aspose/Slides/Foss/slide.h>
#include <Aspose/Slides/Foss/slide_collection.h>
#include <Aspose/Slides/Foss/text_frame.h>

using namespace Aspose::Slides::Foss;
using namespace Aspose::Slides::Foss::Drawing;

int main() {
    Presentation prs;
    auto& shape = prs.slides()[0].shapes().add_auto_shape(
        ShapeType::ROUND_CORNER_RECTANGLE, 100, 100, 400, 150
    );
    shape.text_frame()->set_text("Solid Fill");

    shape.fill_format().set_fill_type(FillType::SOLID);
    shape.fill_format().solid_fill_color().set_color(Color::from_argb(255, 30, 80, 180));

    prs.save("solid.pptx", SaveFormat::PPTX);
    return 0;
}

Penuh Linier Gradien

Stop gradien memungkinkan Anda untuk berbaur dari satu warna ke yang lain di seluruh bentuk:

#include <Aspose/Slides/Foss/auto_shape.h>
#include <Aspose/Slides/Foss/drawing/color.h>
#include <Aspose/Slides/Foss/export/save_format.h>
#include <Aspose/Slides/Foss/fill_format.h>
#include <Aspose/Slides/Foss/fill_type.h>
#include <Aspose/Slides/Foss/gradient_format.h>
#include <Aspose/Slides/Foss/gradient_shape.h>
#include <Aspose/Slides/Foss/presentation.h>
#include <Aspose/Slides/Foss/shape_collection.h>
#include <Aspose/Slides/Foss/shape_type.h>
#include <Aspose/Slides/Foss/slide.h>
#include <Aspose/Slides/Foss/slide_collection.h>

using namespace Aspose::Slides::Foss;
using namespace Aspose::Slides::Foss::Drawing;

int main() {
    Presentation prs;
    auto& shape = prs.slides()[0].shapes().add_auto_shape(
        ShapeType::RECTANGLE, 100, 100, 400, 150
    );

    auto& ff = shape.fill_format();
    ff.set_fill_type(FillType::GRADIENT);
    auto& gf = ff.gradient_format();
    gf.set_gradient_shape(GradientShape::LINEAR);
    gf.set_linear_gradient_angle(90);   // top-to-bottom

    gf.gradient_stops().add(0.0f, Color::from_argb(255, 30, 80, 180));   // top: blue
    gf.gradient_stops().add(1.0f, Color::from_argb(255, 0, 200, 160));   // bottom: teal

    prs.save("gradient.pptx", SaveFormat::PPTX);
    return 0;
}

2D Visual Effects

Bayangan Drop Luar

Pasanglah drop shadow semi-transparan pada bentuk apapun:

#include <Aspose/Slides/Foss/auto_shape.h>
#include <Aspose/Slides/Foss/drawing/color.h>
#include <Aspose/Slides/Foss/effect_format.h>
#include <Aspose/Slides/Foss/export/save_format.h>
#include <Aspose/Slides/Foss/fill_format.h>
#include <Aspose/Slides/Foss/fill_type.h>
#include <Aspose/Slides/Foss/presentation.h>
#include <Aspose/Slides/Foss/shape_collection.h>
#include <Aspose/Slides/Foss/shape_type.h>
#include <Aspose/Slides/Foss/slide.h>
#include <Aspose/Slides/Foss/slide_collection.h>
#include <Aspose/Slides/Foss/text_frame.h>

using namespace Aspose::Slides::Foss;
using namespace Aspose::Slides::Foss::Drawing;

int main() {
    Presentation prs;
    auto& shape = prs.slides()[0].shapes().add_auto_shape(
        ShapeType::ROUND_CORNER_RECTANGLE, 100, 100, 350, 150
    );
    shape.text_frame()->set_text("Drop Shadow");

    shape.fill_format().set_fill_type(FillType::SOLID);
    shape.fill_format().solid_fill_color().set_color(Color::white);

    auto& ef = shape.effect_format();
    ef.enable_outer_shadow_effect();
    auto* shadow = ef.outer_shadow_effect();
    shadow->set_blur_radius(12);
    shadow->set_direction(315);   // upper-left
    shadow->set_distance(8);
    shadow->shadow_color().set_color(Color::from_argb(100, 0, 0, 0));

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

Efek Terang

Sebuah halo berwarna di sekitar tepi bentuk:

#include <Aspose/Slides/Foss/auto_shape.h>
#include <Aspose/Slides/Foss/drawing/color.h>
#include <Aspose/Slides/Foss/effect_format.h>
#include <Aspose/Slides/Foss/export/save_format.h>
#include <Aspose/Slides/Foss/fill_format.h>
#include <Aspose/Slides/Foss/fill_type.h>
#include <Aspose/Slides/Foss/presentation.h>
#include <Aspose/Slides/Foss/shape_collection.h>
#include <Aspose/Slides/Foss/shape_type.h>
#include <Aspose/Slides/Foss/slide.h>
#include <Aspose/Slides/Foss/slide_collection.h>

using namespace Aspose::Slides::Foss;
using namespace Aspose::Slides::Foss::Drawing;

int main() {
    Presentation prs;
    auto& shape = prs.slides()[0].shapes().add_auto_shape(
        ShapeType::ELLIPSE, 150, 100, 250, 250
    );
    shape.fill_format().set_fill_type(FillType::SOLID);
    shape.fill_format().solid_fill_color().set_color(Color::from_argb(255, 20, 60, 140));

    auto& ef = shape.effect_format();
    ef.enable_glow_effect();
    auto* glow = ef.glow_effect();
    glow->set_radius(20);
    glow->color().set_color(Color::from_argb(200, 0, 180, 255));

    prs.save("glow.pptx", SaveFormat::PPTX);
    return 0;
}

3D Formatting

Bevel dan Bahan

Pengelolaan three_d_format() Metode ini memberikan bentuk datar apapun dengan tampilan tiga dimensi. menggabungkan bevel dengan preset kamera dan bahan untuk hasil yang paling kaya:

#include <Aspose/Slides/Foss/auto_shape.h>
#include <Aspose/Slides/Foss/bevel_preset_type.h>
#include <Aspose/Slides/Foss/camera_preset_type.h>
#include <Aspose/Slides/Foss/drawing/color.h>
#include <Aspose/Slides/Foss/export/save_format.h>
#include <Aspose/Slides/Foss/fill_format.h>
#include <Aspose/Slides/Foss/fill_type.h>
#include <Aspose/Slides/Foss/light_rig_preset_type.h>
#include <Aspose/Slides/Foss/lighting_direction.h>
#include <Aspose/Slides/Foss/material_preset_type.h>
#include <Aspose/Slides/Foss/presentation.h>
#include <Aspose/Slides/Foss/shape_collection.h>
#include <Aspose/Slides/Foss/shape_type.h>
#include <Aspose/Slides/Foss/slide.h>
#include <Aspose/Slides/Foss/slide_collection.h>
#include <Aspose/Slides/Foss/text_frame.h>
#include <Aspose/Slides/Foss/three_d_format.h>

using namespace Aspose::Slides::Foss;
using namespace Aspose::Slides::Foss::Drawing;

int main() {
    Presentation prs;
    auto& shape = prs.slides()[0].shapes().add_auto_shape(
        ShapeType::RECTANGLE, 150, 150, 300, 130
    );
    shape.text_frame()->set_text("Metal Button");

    // Blue solid fill
    shape.fill_format().set_fill_type(FillType::SOLID);
    shape.fill_format().solid_fill_color().set_color(Color::from_argb(255, 20, 70, 160));

    // 3D bevel + camera + light + material
    auto& tdf = shape.three_d_format();
    tdf.bevel_top().set_bevel_type(BevelPresetType::CIRCLE);
    tdf.bevel_top().set_width(10);
    tdf.bevel_top().set_height(5);
    tdf.camera().set_camera_type(CameraPresetType::PERSPECTIVE_ABOVE);
    tdf.light_rig().set_light_type(LightRigPresetType::BALANCED);
    tdf.light_rig().set_direction(LightingDirection::TOP);
    tdf.set_material(MaterialPresetType::METAL);
    tdf.set_depth(20);

    prs.save("metal-button.pptx", SaveFormat::PPTX);
    return 0;
}

Menggabungkan Efek pada Bentuk yang Sama

Bayangan dan pemformatan 3D dapat hidup bersama pada satu bentuk, memungkinkan desain “kartu” yang dipoles:

#include <Aspose/Slides/Foss/auto_shape.h>
#include <Aspose/Slides/Foss/bevel_preset_type.h>
#include <Aspose/Slides/Foss/camera_preset_type.h>
#include <Aspose/Slides/Foss/drawing/color.h>
#include <Aspose/Slides/Foss/effect_format.h>
#include <Aspose/Slides/Foss/export/save_format.h>
#include <Aspose/Slides/Foss/fill_format.h>
#include <Aspose/Slides/Foss/fill_type.h>
#include <Aspose/Slides/Foss/material_preset_type.h>
#include <Aspose/Slides/Foss/presentation.h>
#include <Aspose/Slides/Foss/shape_collection.h>
#include <Aspose/Slides/Foss/shape_type.h>
#include <Aspose/Slides/Foss/slide.h>
#include <Aspose/Slides/Foss/slide_collection.h>
#include <Aspose/Slides/Foss/text_frame.h>
#include <Aspose/Slides/Foss/three_d_format.h>

using namespace Aspose::Slides::Foss;
using namespace Aspose::Slides::Foss::Drawing;

int main() {
    Presentation prs;
    auto& shape = prs.slides()[0].shapes().add_auto_shape(
        ShapeType::ROUND_CORNER_RECTANGLE, 120, 120, 360, 150
    );
    shape.text_frame()->set_text("Premium Card");

    // Fill
    shape.fill_format().set_fill_type(FillType::SOLID);
    shape.fill_format().solid_fill_color().set_color(Color::from_argb(255, 30, 80, 180));

    // 3D bevel
    auto& tdf = shape.three_d_format();
    tdf.bevel_top().set_bevel_type(BevelPresetType::CIRCLE);
    tdf.bevel_top().set_width(8);
    tdf.camera().set_camera_type(CameraPresetType::PERSPECTIVE_ABOVE);
    tdf.set_material(MaterialPresetType::PLASTIC);

    // Drop shadow
    auto& ef = shape.effect_format();
    ef.enable_outer_shadow_effect();
    auto* shadow = ef.outer_shadow_effect();
    shadow->set_blur_radius(14);
    shadow->set_direction(270);
    shadow->set_distance(8);
    shadow->shadow_color().set_color(Color::from_argb(70, 0, 0, 0));

    prs.save("premium-card.pptx", SaveFormat::PPTX);
    return 0;
}
