Connectors

Travailler avec les connecteurs — Aspose.Slides FOSS pour Python

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

Index des sites de connexion

Chaque forme expose quatre sites 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° (les plus courants pour les diagrammes de type organigramme)
`ShapeType.BENT_CONNECTOR2`	Un coude de 90°
`ShapeType.BENT_CONNECTOR4`	Trois coudes à 90°
`ShapeType.STRAIGHT_CONNECTOR1`	Ligne droite directe
`ShapeType.CURVED_CONNECTOR2`	Courbe lisse simple
`ShapeType.CURVED_CONNECTOR3`	Courbe à double coude

Mise en forme d’un connecteur

Les connecteurs prennent en charge le même line_format propriétés que d’autres formes :

from aspose.slides_foss.drawing import Color
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:

    box1 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 50, 150, 150, 60)
    box2 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 400, 150, 150, 60)

    conn = slide.shapes.add_connector(ShapeType.BENT_CONNECTOR3, 0, 0, 10, 10)
    conn.start_shape_connected_to = box1
    conn.start_shape_connection_site_index = 3
    conn.end_shape_connected_to = box2
    conn.end_shape_connection_site_index = 1

    # Style the connector line
    conn.line_format.width = 2.5
    conn.line_format.dash_style = LineDashStyle.DASH
    conn.line_format.fill_format.solid_fill_color.color = Color.dark_blue
