Connectors

Arbejde med forbindelser — Aspose.Slides FOSS for Python

Connectors er former, der visuelt forbinder to andre former med en linje. Aspose.Slides FOSS for Python understøtter bøjede, lige og kurvede forbindelser. Tilslutningspunkterne på en form identificeres ved integer tilslutningssted indeks.

Forbindelsessted-indekser

Hver form har fire standardforbindelsessteder:

Typer af forbindelsesformer

ShapeTypeBeskrivelse
ShapeType.BENT_CONNECTOR3To 90° bøjninger (mest almindelige i flowchart‑lignende diagrammer)
ShapeType.BENT_CONNECTOR2Én 90° bøjning
ShapeType.BENT_CONNECTOR4Tre 90° bøjninger
ShapeType.STRAIGHT_CONNECTOR1Direkte lige linje
ShapeType.CURVED_CONNECTOR2Enkelt glat kurve
ShapeType.CURVED_CONNECTOR3Kurve med dobbelt bøjning

Formatering af en forbindelse

Forbindelser understøtter det samme line_format egenskaber 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
