Connectors

Arbeiten mit Connectors Aspose.Slides FOSS für Python

Konnektoren sind Formen, die zwei andere Forme visuell mit einer Linie verbinden. Aspose.Slides FOSS für Python unterstützt gebogene, gerade und gekrümmte Verbindungsstellen. Die Verbindungspunkte auf einer Form werden durch eine ganze Zahl identifiziert. Verbindungsstandort-Index.

Verbindungsseiten-Index

Jede Form zeigt vier Standardverbindungsstellen:

Index der	Seite
`0`	Oberste Seite
`1`	Links .
`2`	Unteren Bereich
`3`	- Ja .

Hinzufügen eines gebogenen Verbinders zwischen zwei Formen

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

    # Create two shapes to connect
    box1 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 50, 150, 150, 60)
    box1.add_text_frame("Start")

    box2 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 400, 150, 150, 60)
    box2.add_text_frame("End")

    # Add a bent connector (position/size are ignored once connected)
    conn = slide.shapes.add_connector(ShapeType.BENT_CONNECTOR3, 0, 0, 10, 10)

    # Connect right side of box1 → left side of box2
    conn.start_shape_connected_to = box1

Verbindungsformtypen

ShapeType	Beschreibung
`ShapeType.BENT_CONNECTOR3`	Zwei 90°-Bögen (am häufigsten für Fließdiagramm)
`ShapeType.BENT_CONNECTOR2`	Eine 90°-Biegung
`ShapeType.BENT_CONNECTOR4`	Drei 90°-Bügen
`ShapeType.STRAIGHT_CONNECTOR1`	Direktgerade
`ShapeType.CURVED_CONNECTOR2`	Einfach glatte Kurve
`ShapeType.CURVED_CONNECTOR3`	Doppelbiegungskurve

Formatierung eines Connectors

Steckverbinder unterstützen die gleichen line_format Eigenschaften als andere Formen:

from aspose.slides_foss import ShapeType, LineDashStyle
from aspose.slides_foss.drawing import Color
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat

with slides.Presentation() as prs:
    slide = prs.slides[0]
    box1 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 50, 150, 150, 60)
    box2 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 400, 150, 150, 60)

    conn = slide.shapes.add_connector(ShapeType.BENT_CONNECTOR3, 0, 0, 10, 10)
    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

    # Style the connector line
    conn.line_format.width = 2.5
    conn.line_format.dash_style = LineDashStyle.DASH
    conn.line_format.fill_format.solid_fill_color.color = Color.dark_blue
