Arbeide med koblinger — Aspose.Slides FOSS for Python

Koblinger er former som visuelt kobler to andre former med en linje. Aspose.Slides FOSS for Python støtter bøyd, rett og kurvet koblinger. Tilkoblingspunktene på en form er identifisert med heltall tilkoblingsstedindekser.

Tilkoblingsstedindekser

Hver form har fire standard tilkoblingssteder:

IndeksSide

1Venstre

3Høyre

Typer av koblingsformer

ShapeTypeBeskrivelse
ShapeType.BENT_CONNECTOR3To 90°‑bøyer (mest vanlig for flytskjema‑stil diagrammer)
ShapeType.BENT_CONNECTOR2En 90°‑bøy
ShapeType.BENT_CONNECTOR4Tre 90°‑bøyer
ShapeType.STRAIGHT_CONNECTOR1Direkte rett linje
ShapeType.CURVED_CONNECTOR2Enkel jevn kurve
ShapeType.CURVED_CONNECTOR3Dobbelbøyd kurve

Formatering av en kobling

Koblinger støtter det samme line_format egenskaper som andre former:

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

    prs.save("styled-connector.pptx", SaveFormat.PPTX)
