Functies en Mogelijkheden

Aspose.Slides FOSS for C++ provides a broad set of capabilities for working with PowerPoint .pptx bestanden programmatically. Deze pagina geeft een overzicht van alle ondersteunde functionaliteitsgebieden met representatieve codevoorbeelden.

Presentatie I/O

Open een bestaande .pptx bestand of maak een nieuw bestand, en sla vervolgens op in PPTX-formaat.

#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;
}

Opmerking: PPTX is het enige ondersteunde opslagformaat. Exporteren naar PDF, HTML, SVG of afbeeldingen is niet beschikbaar.

Onbekende XML-onderdelen in het bronbestand worden bij het opslaan letterlijk behouden, zodat het openen en opnieuw opslaan van een .pptx nooit inhoud zal verwijderen die de bibliotheek nog niet begrijpt.

Dia’s beheren

Dia’s toevoegen, verwijderen, dupliceren en herschikken.

#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;
}

Vormen

AutoShapes, PictureFrames, tabellen en connectors aan een dia toevoegen.

    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);

    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);

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

Tekstopmaak

Formatteer tekst op alinea- en tekenniveau met behulp van PortionFormat.

#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/nullable_bool.h>
#include <Aspose/Slides/Foss/paragraph.h>
#include <Aspose/Slides/Foss/paragraph_collection.h>
#include <Aspose/Slides/Foss/portion.h>
#include <Aspose/Slides/Foss/portion_collection.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 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 stelt de eigenschap expliciet in; NullableBool::NOT_DEFINED erft van de slide‑master.

Vultypen

Pas effen, verloop, patroon of afbeeldingvullingen toe op vormen.

#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;
}

Visuele effecten

Pas buitenschaduw, gloed, zachte rand, vervaging, reflectie en binnenschaduw toe op vormen.

De effecteigenschappen zijn toegankelijk via shape.effect_format(). De subobjecten die worden geretourneerd door outer_shadow_effect(), glow_effect(), en soortgelijke methoden zijn pointers — roep ze aan met ->.

#include <Aspose/Slides/Foss/auto_shape.h>
#include <Aspose/Slides/Foss/drawing/color.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, 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

Pas 3D-afschuiningsrand, camera, lichtopstelling, materiaal en extrusiediepte toe via shape.three_d_format(). Dit regelt de visuele diepte en het verlichtingsmodel voor vormweergave in PPTX-viewers die 3D-effecten ondersteunen.

    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);
    return 0;
}

Sprekersnotities

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