Kaip C++ programoje sujungti figūras su jungtukais

Jungikliai „Aspose.Slides FOSS“ yra linijinės figūros, kurios prisijungia prie connection sites kitų figūrų. Kai perkate sujungtą figūrą, jungiklio galutinis taškas juda kartu su ja. Dažniausiai naudojamas jungiklio tipas yra BENT_CONNECTOR3, kuris aplengia kliūtis vienu alkūnės posūkiu.

Būtinosios sąlygos 

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 .

Prisijungimo vietų indeksai

Kiekviena figūra turi keturis numeruotus jungimo taškus:

IndeksasPozicija
0Viršuje centre
1Kairėje centre
2Apačioje centre
3Dešinėje centre

Sujunkite dvi formas 

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

    // Add two rectangles
    auto& box1 = slide.shapes().add_auto_shape(

Vietos žymeklio ribos (0, 0, 10, 10), perduotos add_connector, yra ignoruojamos, kai nustatomi ryšio galiniai taškai; PowerPoint peradresuoja jungiklį į prijungtus objektus.

Jungčių tipai 

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;
