Werken met connectors — Aspose.Slides FOSS voor Python

Connectoren zijn vormen die visueel twee andere vormen met een lijn verbinden. Aspose.Slides FOSS voor Python ondersteunt gebogen, rechte en kromme connectoren. De aansluitpunten op een vorm worden geïdentificeerd door een integer aansluitpuntindexen.

Verbindingssite‑indexen

Elke vorm biedt vier standaard verbindingssites:

IndexZijde
0Boven
1Links
2Onder
3Rechts

Een gebogen connector tussen twee vormen toevoegen 

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]

    # 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
    conn.start_shape_connection_site_index = 3   # right
    conn.end_shape_connected_to = box2
    conn.end_shape_connection_site_index = 1     # left

Connectorvorm‑typen

ShapeTypeBeschrijving
ShapeType.BENT_CONNECTOR3Twee 90° buigingen (meest gebruikelijk voor stroomdiagram-achtige diagrammen)
ShapeType.BENT_CONNECTOR2Één 90° buiging
ShapeType.BENT_CONNECTOR4Drie 90° buigingen
ShapeType.STRAIGHT_CONNECTOR1Directe rechte lijn
ShapeType.CURVED_CONNECTOR2Enkele vloeiende boog
ShapeType.CURVED_CONNECTOR3Dubbele-buiging curve

Stroomschema met meerdere connectoren 

from aspose.slides_foss import ShapeType
import aspose.slides_foss as slides
from aspose.slides_foss.export import SaveFormat


def add_box(slide, text, x, y, w=160, h=50):
    s = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, x, y, w, h)

    connect(slide, process, 2, end, 0)      # process → end (bottom to top)

Een connector opmaken

Connectoren ondersteunen hetzelfde line_format eigenschappen als andere vormen:

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)
