Fitur dan Kemampuan

Aspose.Slides FOSS for C++ provides a broad set of capabilities for working with PowerPoint .pptx file secara programatik. Halaman ini mencantumkan semua area fitur yang didukung dengan contoh kode representatif.

I/O Presentasi

Buka yang sudah ada .pptx file atau buat yang baru, lalu simpan kembali ke 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;
}

Catatan: PPTX adalah satu-satunya format penyimpanan yang didukung. Ekspor ke PDF, HTML, SVG, atau gambar tidak tersedia.

Bagian XML yang tidak dikenal dalam file sumber dipertahankan persis saat disimpan, sehingga membuka dan menyimpan kembali sebuah .pptx tidak akan pernah menghapus konten yang belum dipahami oleh perpustakaan.

Manajemen Slide

Tambah, hapus, kloning, dan urutkan kembali slide.

#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;
}

Bentuk

Tambahkan AutoShapes, PictureFrames, Tabel, dan Connectors ke sebuah slide.

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

Pemformatan Teks

Format teks pada tingkat paragraf dan karakter menggunakan 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/portion_format.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 menetapkan properti secara eksplisit; NullableBool::NOT_DEFINED mewarisi dari master slide.

Jenis Isian

Terapkan isian padat, gradasi, pola, atau gambar pada 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/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;
}

Efek Visual

Terapkan bayangan luar, cahaya bersinar, tepi lembut, blur, refleksi, dan bayangan dalam pada bentuk.

Properti efek dapat diakses melalui shape.effect_format(). Sub-objek yang dikembalikan oleh outer_shadow_effect(), glow_effect(), dan metode serupa adalah penunjuk — panggil mereka dengan ->.

#include <Aspose/Slides/Foss/auto_shape.h>

    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

    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;
