Come collegare forme con connettori in Python

I connettori in Aspose.Slides FOSS sono forme lineari che si collegano ai punti di connessione su altre forme. Quando sposti una forma collegata, l’estremità del connettore si muove con essa. Il tipo di connettore più comune è BENT_CONNECTOR3, che aggira gli ostacoli con una singola curva a gomito.

Prerequisiti 

pip install aspose-slides-foss

Indici del sito di connessione

Ogni forma ha quattro punti di connessione numerati:

IndexPosition
0Centro superiore
1Centro sinistro
2Centro inferiore
3Centro destro

from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]

    # Add two rectangles
    box1 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 50, 200, 200, 100)
    box2 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 450, 200, 200, 100)

    box1.add_text_frame("Start")
    box2.add_text_frame("End")

    # Add a bent connector (initial bounds are overwritten by the connection)
    conn = slide.shapes.add_connector(ShapeType.BENT_CONNECTOR3, 0, 0, 10, 10)

    # Connect right side of box1 (site 3) to left side of box2 (site 1)
    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

    prs.save("connected.pptx", SaveFormat.PPTX)

I limiti del segnaposto (0, 0, 10, 10) passati a add_connector vengono ignorati una volta impostati i punti di connessione; PowerPoint reindirizza il connettore alle forme collegate.
