Fonctionnalités et capacités

Aspose.Slides FOSS for C++ provides a broad set of capabilities for working with PowerPoint .pptx fichiers de manière programmatique. Cette page répertorie toutes les zones de fonctionnalités prises en charge avec des exemples de code représentatifs.

Entrée/Sortie de présentation

Ouvrez un existant .pptx fichier ou créez‑en un nouveau, puis enregistrez‑le au format PPTX.

#include <Aspose/Slides/Foss/presentation.h>
#include <Aspose/Slides/Foss/export/save_format.h>
#include <Aspose/Slides/Foss/slide.h>
#include <Aspose/Slides/Foss/slide_collection.h>

#include <iostream>

using namespace Aspose::Slides::Foss;

int main() {
    // Open an existing presentation
    {
        Presentation pres("input.pptx");
        std::cout << "Slide count: " << pres.slides().size() << std::endl;
        pres.save("output.pptx", SaveFormat::PPTX);
    }

    // Create a new presentation (starts with one blank slide)
    {
        Presentation pres;
        pres.save("new.pptx", SaveFormat::PPTX);
    }

    return 0;
}

Remarque : PPTX est le seul format d’enregistrement pris en charge. L’exportation vers PDF, HTML, SVG ou des images n’est pas disponible.

Les parties XML inconnues du fichier source sont conservées mot pour mot lors de l’enregistrement, de sorte qu’ouvrir et réenregistrer un .pptx ne supprimera jamais le contenu que la bibliothèque ne comprend pas encore.

Gestion des diapositives

Ajoutez, supprimez, clonez et réorganisez les diapositives.

#include <Aspose/Slides/Foss/presentation.h>
#include <Aspose/Slides/Foss/export/save_format.h>
#include <Aspose/Slides/Foss/layout_slide.h>
#include <Aspose/Slides/Foss/slide.h>
#include <Aspose/Slides/Foss/slide_collection.h>

#include <iostream>

using namespace Aspose::Slides::Foss;

int main() {
    Presentation pres;

    // Access the first slide
    auto& slide = pres.slides()[0];

    // Add an additional blank slide at the end
    auto* layout = dynamic_cast<ILayoutSlide*>(&pres.layout_slides()[0]);
    pres.slides().add_empty_slide(layout);

    std::cout << "Total slides: " << pres.slides().size() << std::endl;
    pres.save("multi-slide.pptx", SaveFormat::PPTX);
    return 0;
}

Formes

Ajoutez des AutoShapes, des PictureFrames, des Tableaux et des Connecteurs à une diapositive.

AutoShapes

#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;

int main() {
    Presentation pres;
    auto& slide = pres.slides()[0];
    // Add a rectangle at (x=50, y=50) with width=300, height=100
    auto& shape = slide.shapes().add_auto_shape(ShapeType::RECTANGLE, 50, 50, 300, 100);
    shape.text_frame()->set_text("Aspose.Slides FOSS");
    pres.save("shapes.pptx", SaveFormat::PPTX);
    return 0;
}

Tableaux

#include <Aspose/Slides/Foss/slide_collection.h>
#include <Aspose/Slides/Foss/table.h>
#include <Aspose/Slides/Foss/text_frame.h>

#include <vector>

using namespace Aspose::Slides::Foss;

int main() {
    Presentation pres;
    auto& slide = pres.slides()[0];
    // Column widths and row heights in points
    std::vector<double> col_widths = {120.0, 120.0, 120.0};
    std::vector<double> row_heights = {40.0, 40.0, 40.0};
    auto& table = slide.shapes().add_table(50, 50, col_widths, row_heights);
    table.rows()[0][0].text_frame()->set_text("Product");
    table.rows()[0][1].text_frame()->set_text("Quantity");

    auto& box1 = slide.shapes().add_auto_shape(ShapeType::RECTANGLE, 50, 100, 150, 60);
    auto& box2 = slide.shapes().add_auto_shape(ShapeType::RECTANGLE, 350, 100, 150, 60);
    auto& conn = slide.shapes().add_connector(ShapeType::BENT_CONNECTOR3, 0, 0, 10, 10);
    conn.set_start_shape_connected_to(&box1);
    conn.set_start_shape_connection_site_index(3);  // right side
    conn.set_end_shape_connected_to(&box2);

#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>

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

int main() {
    Presentation pres;
    auto& slide = pres.slides()[0];
    auto& shape = slide.shapes().add_auto_shape(ShapeType::RECTANGLE, 50, 50, 500, 150);
    shape.text_frame()->set_text("Bold blue heading");

    auto& fmt = shape.text_frame()->paragraphs()[0].portions()[0].portion_format();
    fmt.set_font_height(28);
    fmt.set_font_bold(NullableBool::TRUE);
    fmt.fill_format().set_fill_type(FillType::SOLID);
    fmt.fill_format().solid_fill_color().set_color(Color::from_argb(255, 0, 70, 127));

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

NullableBool::TRUE définit la propriété explicitement ; NullableBool::NOT_DEFINED hérite du masque de diapositive.

Types de remplissage

Appliquez des remplissages plein, dégradé, motif ou image aux formes.

#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>

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

int main() {
    Presentation pres;
    auto& slide = pres.slides()[0];
    auto& shape = slide.shapes().add_auto_shape(ShapeType::RECTANGLE, 50, 50, 300, 150);

    // Solid fill
    shape.fill_format().set_fill_type(FillType::SOLID);
    shape.fill_format().solid_fill_color().set_color(Color::from_argb(255, 30, 120, 200));

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

Effets visuels

Appliquez une ombre externe, une lueur, un bord doux, un flou, un reflet et une ombre interne aux formes.

Les propriétés d’effet sont accessibles via shape.effect_format(). Les sous-objets renvoyés par outer_shadow_effect(), glow_effect(), et des méthodes similaires sont pointeurs — appelez‑les avec ->.

    auto& shape = slide.shapes().add_auto_shape(ShapeType::RECTANGLE, 100, 100, 200, 100);

    auto& ef = shape.effect_format();

    // Outer drop shadow
    ef.enable_outer_shadow_effect();
    auto* shadow = ef.outer_shadow_effect();
    shadow->set_blur_radius(10);
    shadow->set_direction(315);
    shadow->set_distance(8);
    shadow->shadow_color().set_color(Color::from_argb(128, 0, 0, 0));

    // Glow effect
    ef.enable_glow_effect();
    auto* glow = ef.glow_effect();
    glow->set_radius(15);
    glow->color().set_color(Color::from_argb(200, 255, 200, 0));

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

3D Formatting

Appliquer un biseau 3D, une caméra, un dispositif d’éclairage, un matériau et une profondeur d’extrusion via shape.three_d_format(). Cela contrôle la profondeur visuelle et le modèle d’éclairage pour le rendu des formes dans les visionneuses PPTX qui prennent en charge les effets 3D.

    auto& slide = pres.slides()[0];
    auto& shape = slide.shapes().add_auto_shape(ShapeType::RECTANGLE, 100, 100, 200, 100);

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

    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_depth(20);
    tdf.set_material(MaterialPresetType::METAL);

    pres.save("3d.pptx", SaveFormat::PPTX);
