Connectors

Bağlayıcılarla Çalışma — Aspose.Slides FOSS for Python

Bağlayıcılar, iki diğer şekli bir çizgiyle görsel olarak bağlayan şekillerdir. Aspose.Slides FOSS for Python bükülmüş, düz ve eğimli bağlayıcıları destekler. Bir şeklin bağlantı noktaları tam sayı ile tanımlanır bağlantı noktası indeksleri.

Bağlantı Sitesi İndeksleri

Her şekil dört standart bağlantı sitesi sunar:

İndeks	Yan
`0`	Üst
`1`	Sol
`2`	Alt
`3`	Sağ

Bağlayıcı Şekil Türleri

ShapeType	Açıklama
`ShapeType.BENT_CONNECTOR3`	İki 90° bükülme (akış diyagramı tarzı şemalar için en yaygın)
`ShapeType.BENT_CONNECTOR2`	Bir 90° bükülme
`ShapeType.BENT_CONNECTOR4`	Üç 90° bükülme
`ShapeType.STRAIGHT_CONNECTOR1`	Doğrudan düz çizgi
`ShapeType.CURVED_CONNECTOR2`	Tek pürüzsüz eğri
`ShapeType.CURVED_CONNECTOR3`	Çift bükülmeli eğri
