Wie man Formen mit Connectors in Python verbindet

Die Anschlüsse in Aspose.Slides FOSS sind Linienformen, die an den Verbindungsstellen Wenn man eine vernetzte Form bewegt, dann bewegen sich die Endpunkte der Verbindung mit ihr. Der häufigste Verbindungstyp ist BENT_CONNECTOR3, die Hindernisse mit einer einzigen Ellenbogenbiegung umgeht.

Voraussetzungen für die Durchführung der Maßnahmen 

pip install aspose-slides-foss

Verbindungsseiten-Index

Jede Form hat vier nummerierte Verbindungsstellen:

0Oberste Mitte
1Links in der Mitte
2Unterhalb der Mitte
3Rechts Mitte

Zwei Formen verbinden 

from aspose.slides_foss import ShapeType
import aspose.slides_foss as slides
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)

Die Grenzen des Platzhalters (0, 0, 10, 10) Übertragen an: add_connector werden ignoriert, sobald die Verbindungsendpunkte festgelegt sind; PowerPoint leitet den Anschluss zu den angeschlossenen Formen um.
