Connectors

Práca s konektormi — Aspose.Slides FOSS pre Python

Konektory sú tvary, ktoré vizuálne spájajú dva ďalšie tvary čiarou. Aspose.Slides FOSS pre Python podporuje ohnuté, rovné a zakrivené konektory. Pripojovacie body na tvare sú identifikované celým číslom indexy pripojovacích miest.

Indexy miest pripojenia

Každý tvar poskytuje štyri štandardné miesta pripojenia:

Index	Strana
`0`	Hore
`1`	Vľavo
`2`	Dole
`3`	Vpravo

Typy tvarov konektorov

ShapeType	Popis
`ShapeType.BENT_CONNECTOR3`	Dva 90° ohyby (najčastejšie pre diagramy typu vývojový diagram)
`ShapeType.BENT_CONNECTOR2`	Jeden 90° ohyb
`ShapeType.BENT_CONNECTOR4`	Tri 90° ohyby
`ShapeType.STRAIGHT_CONNECTOR1`	Priama rovná čiara
`ShapeType.CURVED_CONNECTOR2`	Jedna hladká krivka
`ShapeType.CURVED_CONNECTOR3`	Krivka s dvojitým ohybom
