Connectors

Bekerja dengan Penyambung — Aspose.Slides FOSS untuk Python

Penyambung adalah bentuk yang secara visual menghubungkan dua bentuk lain dengan satu garis. Aspose.Slides FOSS untuk Python menyokong penyambung bengkok, lurus, dan melengkung. Titik sambungan pada satu bentuk dikenali dengan integer indeks tapak sambungan.

Indeks Tapak Sambungan

Setiap bentuk menyediakan empat tapak sambungan standard:

Indeks	Sisi
`0`	Atas
`1`	Kiri
`2`	Bawah
`3`	Kanan

Jenis Bentuk Penyambung

ShapeType	Deskripsi
`ShapeType.BENT_CONNECTOR3`	Dua lengkungan 90° (paling umum untuk diagram gaya carta alir)
`ShapeType.BENT_CONNECTOR2`	Satu lengkungan 90°
`ShapeType.BENT_CONNECTOR4`	Tiga lengkungan 90°
`ShapeType.STRAIGHT_CONNECTOR1`	Garis lurus langsung
`ShapeType.CURVED_CONNECTOR2`	Lengkung licin tunggal
`ShapeType.CURVED_CONNECTOR3`	Lengkung dua bengkok
