Connectors

Travailler avec les connecteurs — Aspose.Slides FOSS pour C++

Les connecteurs sont des formes qui relient visuellement deux autres formes par une ligne. Aspose.Slides FOSS pour C++ prend en charge les connecteurs coudés, droits et courbes. Les points de connexion sur une forme sont identifiés par un entier index des sites de connexion.

Index d’emplacements de connexion

Chaque forme expose quatre emplacements de connexion standard :

Index	Côté
`0`	Haut
`1`	Gauche
`2`	Bas
`3`	Droite

Types de formes de connecteur

ShapeType	Description
`ShapeType::BENT_CONNECTOR3`	Deux coudes de 90 degrés (les plus courants pour les diagrammes de type organigramme)
`ShapeType::BENT_CONNECTOR2`	Un coude de 90 degrés
`ShapeType::BENT_CONNECTOR4`	Trois coudes à 90 degrés
`ShapeType::STRAIGHT_CONNECTOR1`	Ligne droite directe
`ShapeType::CURVED_CONNECTOR2`	Courbe lisse unique
`ShapeType::CURVED_CONNECTOR3`	Courbe à double coude
