Hoe Vormen Verbinden met Connectoren in Python

Connectors in Aspose.Slides FOSS zijn lijnvormen die zich hechten aan connection sites op andere vormen. Wanneer je een verbonden vorm verplaatst, beweegt het connector‑eindpunt mee. Het meest voorkomende connector‑type is BENT_CONNECTOR3, die rond obstakels routeert met een enkele elleboogbocht.

Vereisten 

pip install aspose-slides-foss

Verbindingssite-indexen

Elke vorm heeft vier genummerde aansluitpunten:

IndexPositie
0Boven midden
1Links midden
2Onder midden
3Rechts midden

Verbind twee vormen 

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)

De placeholder‑grenzen (0, 0, 10, 10) die aan add_connector worden doorgegeven, worden genegeerd zodra de verbindings‑eindpunten zijn ingesteld; PowerPoint leidt de connector opnieuw naar de gekoppelde vormen.

Connector Types 

from aspose.slides_foss import ShapeType

# Straight line
ShapeType.STRAIGHT_CONNECTOR1

# Single elbow (L-shape)
ShapeType.BENT_CONNECTOR2

# Double elbow (Z-shape): most common
ShapeType.BENT_CONNECTOR3

# Curved connector
ShapeType.CURVED_CONNECTOR3
