Cara Menghubungkan Bentuk dengan Penghubung di C++

Konektor di Aspose.Slides FOSS adalah bentuk garis yang menempel pada situs koneksi pada bentuk lain. Saat Anda memindahkan bentuk yang terhubung, titik akhir konektor bergerak bersamanya. Jenis konektor yang paling umum adalah BENT_CONNECTOR3, yang mengarahkan di sekitar rintangan dengan satu tikungan siku.

Prasyarat 

git clone https://github.com/aspose-slides-foss/Aspose.Slides-FOSS-for-Cpp.git
cd Aspose.Slides-FOSS-for-Cpp && mkdir build && cd build
cmake .. && cmake --build .

Indeks Situs Koneksi

Setiap bentuk memiliki empat situs koneksi bernomor:

IndexPosisi
0Tengah atas
1Tengah kiri
2Tengah bawah
3Tengah kanan

Hubungkan Dua Bentuk 

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

int main() {
    namespace asf = Aspose::Slides::Foss;

    asf::Presentation prs;
    auto& slide = prs.slides()[0];

    // Add two rectangles
    auto& box1 = slide.shapes().add_auto_shape(
        asf::ShapeType::RECTANGLE, 50, 200, 200, 100);
    auto& box2 = slide.shapes().add_auto_shape(
        asf::ShapeType::RECTANGLE, 450, 200, 200, 100);

    box1.text_frame()->set_text("Start");
    box2.text_frame()->set_text("End");

    // Add a bent connector (initial bounds are overwritten by the connection)
    auto& conn = slide.shapes().add_connector(
        asf::ShapeType::BENT_CONNECTOR3, 0, 0, 10, 10);

    // Connect right side of box1 (site 3) to left side of box2 (site 1)
    conn.set_start_shape_connected_to(&box1);
    conn.set_start_shape_connection_site_index(3);
    conn.set_end_shape_connected_to(&box2);
    conn.set_end_shape_connection_site_index(1);

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

Batas placeholder (0, 0, 10, 10) yang diteruskan ke add_connector diabaikan setelah titik akhir koneksi diatur; PowerPoint mengarahkan ulang konektor ke bentuk yang terlampir.

Tipe Konektor 

namespace asf = Aspose::Slides::Foss;

// Straight line
asf::ShapeType::STRAIGHT_CONNECTOR1;

// Single elbow (L-shape)
asf::ShapeType::BENT_CONNECTOR2;

// Double elbow (Z-shape): most common
asf::ShapeType::BENT_CONNECTOR3;

// Curved connector
asf::ShapeType::CURVED_CONNECTOR3;

Gaya Garis Penghubung 

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

int main() {
    namespace asf = Aspose::Slides::Foss;

    asf::Presentation prs;
    auto& slide = prs.slides()[0];

    auto& box1 = slide.shapes().add_auto_shape(
        asf::ShapeType::RECTANGLE, 50, 150, 180, 80);
    auto& box2 = slide.shapes().add_auto_shape(
        asf::ShapeType::RECTANGLE, 500, 300, 180, 80);

    auto& conn = slide.shapes().add_connector(
        asf::ShapeType::BENT_CONNECTOR3, 0, 0, 10, 10);
    conn.set_start_shape_connected_to(&box1);
    conn.set_start_shape_connection_site_index(2);   // bottom of box1
    conn.set_end_shape_connected_to(&box2);
    conn.set_end_shape_connection_site_index(0);     // top of box2

    // Style: dashed blue line, 2 pt width
    auto& lf = conn.line_format();
    lf.set_width(2.0);
    lf.fill_format().solid_fill_color().set_color(asf::Color::blue);
    lf.set_dash_style(asf::LineDashStyle::DASH);

    prs.save("styled-connector.pptx", asf::SaveFormat::PPTX);
    return 0;
}
