Ciri-ciri dan Keupayaan

Aspose.Slides FOSS for C++ provides a broad set of capabilities for working with PowerPoint .pptx fail secara programatik. Halaman ini menyenaraikan semua kawasan ciri yang disokong dengan contoh kod yang representatif.

I/O Persembahan

Buka yang sedia ada .pptx fail atau buat yang baru, kemudian 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;
}

Nota: PPTX adalah satu-satunya format simpan yang disokong. Mengeksport ke PDF, HTML, SVG, atau imej tidak tersedia.

Bahagian XML yang tidak diketahui dalam fail sumber dipelihara secara verbatim semasa menyimpan, jadi membuka dan menyimpan semula satu .pptx tidak akan pernah menanggalkan kandungan yang belum difahami oleh perpustakaan.

Pengurusan Slaid

Tambah, buang, klon, dan susun semula slaid.

#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

Tambah AutoShapes, PictureFrames, Jadual, dan Penyambung ke slaid.

AutoShapes 

#include <Aspose/Slides/Foss/auto_shape.h>
#include <Aspose/Slides/Foss/export/save_format.h>
#include <Aspose/Slides/Foss/presentation.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;

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;
}

Jadual

#include <Aspose/Slides/Foss/slide.h>
#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");
    table.rows()[0][2].text_frame()->set_text("Price");
    pres.save("table.pptx", SaveFormat::PPTX);
    return 0;
}

Penyambung 

#include <Aspose/Slides/Foss/auto_shape.h>
#include <Aspose/Slides/Foss/connector.h>
#include <Aspose/Slides/Foss/export/save_format.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>

using namespace Aspose::Slides::Foss;

int main() {
    Presentation pres;
    auto& slide = pres.slides()[0];
    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);
    conn.set_end_shape_connection_site_index(1);    // left side
    pres.save("connector.pptx", SaveFormat::PPTX);
    return 0;
}

Pemformatan Teks

Formatkan teks pada peringkat perenggan dan aksara 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/presentation.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 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 sifat secara eksplisit; NullableBool::NOT_DEFINED mewarisi daripada slide master.

Jenis Isian

Terapkan isian pepejal, gradien, corak, 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;
}

Kesan Visual

Terapkan bayang luar, cahaya berkilau, tepi lembut, kabur, pantulan, dan bayang dalam pada bentuk.

Sifat kesan boleh diakses melalui shape.effect_format(). Sub-objek yang dikembalikan oleh outer_shadow_effect(), glow_effect(), dan kaedah serupa adalah penunjuk — panggil mereka dengan ->.

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

    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

Terapkan bevel 3D, kamera, rig cahaya, bahan, dan kedalaman ekstrusi melalui shape.three_d_format(). Ini mengawal kedalaman visual dan model pencahayaan untuk rendering bentuk dalam penonton PPTX yang menyokong kesan 3D.

#include <Aspose/Slides/Foss/three_d_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, 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;
