Connectors

Lucrul cu Conectori — Aspose.Slides FOSS pentru Python

Conectorii sunt forme care leagă vizual alte două forme cu o linie. Aspose.Slides FOSS pentru Python suportă conectori îndoiți, drepți și curbați. Punctele de conectare pe o formă sunt identificate prin numere întregi indecși de site de conectare.

Indecși de Site de Conexiune

Fiecare formă expune patru site-uri de conexiune standard:

Index	Latură
`0`	Sus
`1`	Stânga
`2`	Jos
`3`	Dreapta

Tipuri de Forme de Conector

ShapeType	Descriere
`ShapeType.BENT_CONNECTOR3`	Două îndoiri de 90° (cele mai comune pentru diagrame de tip fluxogramă)
`ShapeType.BENT_CONNECTOR2`	O îndoitură de 90°
`ShapeType.BENT_CONNECTOR4`	Trei coturi de 90°
`ShapeType.STRAIGHT_CONNECTOR1`	Linie dreaptă directă
`ShapeType.CURVED_CONNECTOR2`	Curbă netedă unică
`ShapeType.CURVED_CONNECTOR3`	Curbă cu dublu cot
