Cara Menghubungkan Bentuk dengan Penghubung di Java

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

Indeks Situs Koneksi

Setiap bentuk memiliki empat situs koneksi bernomor:

Index	Position
`0`	Pusat atas
`1`	Pusat kiri
`2`	Pusat bawah
`3`	Pusat kanan

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

Tipe Konektor

import org.aspose.slides.foss.ShapeType;

// Straight line
ShapeType.STRAIGHT_CONNECTOR1

// Single elbow (L-shape)
ShapeType.BENT_CONNECTOR2

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

// Curved connector
ShapeType.CURVED_CONNECTOR3
