Connectors

Darbs ar savienotājiem — Aspose.Slides FOSS for Python

Savienotāji ir formas, kas vizuāli savieno divas citas formas ar līniju. Aspose.Slides FOSS priekš Python atbalsta saliektus, taisnus un izliekus savienotājus. Savienojuma punkti uz formas tiek identificēti ar veseliem skaitļiem savienojuma vietas indeksi.

Savienojuma vietas indeksi

Katra forma piedāvā četrus standarta savienojuma vietas:

Indekss	Sāns
`0`	Augšējais
`1`	Kreisais
`2`	Apakšējais
`3`	Labais

Savienotāja formas veidi

ShapeType	Apraksts
`ShapeType.BENT_CONNECTOR3`	Divas 90° pagriezieni (visbiežāk izmantoti plūsmas diagrammu tipa diagrammās)
`ShapeType.BENT_CONNECTOR2`	Viens 90° pagrieziens
`ShapeType.BENT_CONNECTOR4`	Trīs 90° pagriezieni
`ShapeType.STRAIGHT_CONNECTOR1`	Tieša taisna līnija
`ShapeType.CURVED_CONNECTOR2`	Viens gluds līkne
`ShapeType.CURVED_CONNECTOR3`	Dubultpagrieziena līkne

Savienotāja formatēšana

Savienotāji atbalsta to pašu line_format īpašības kā citām formām:

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]

    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
