Kako povezati oblike sa konektorima u C++

Konektori u Aspose.Slides FOSS su linijski oblici koji se pričvršćuju na mesta spajanja na drugim oblicima. Kada pomerite povezani oblik, krajnja tačka konektora se pomera zajedno sa njim. Najčešći tip konektora je BENT_CONNECTOR3, koji se zaobilaženjem prepreka kreće sa jednim laktastim savijanjem.

Preduslovi 

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 .

Индекси локација везе

Svaki oblik ima četiri numerisana mesta za povezivanje:

IndexPosition
0Gornji centar
1Levi centar
2Donji centar
3Desni centar

Poveži dva oblika 

#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;
}

Granice rezervacije (0, 0, 10, 10) prosleđene u add_connector se ignorišu kada se postave krajnje tačke veze; PowerPoint preusmerava konektor na priložene oblike.

Типови конектора 

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;
