Python'da Şekilleri Bağlayıcılarla Bağlama

Aspose.Slides FOSS’taki bağlayıcılar, diğer şekillerdeki bağlantı noktalarına bağlanan çizgi şekilleridir. Bağlı bir şekli hareket ettirdiğinizde, bağlayıcı uç noktası da onunla birlikte hareket eder. En yaygın bağlayıcı türü BENT_CONNECTOR3‘dir, bu da tek bir dirsek bükülmesiyle engellerin etrafından yönlendirir.

İki Şekli Bağla 

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]

    # Add two rectangles
    box1 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 50, 200, 200, 100)
    box2 = slide.shapes.add_auto_shape(ShapeType.RECTANGLE, 450, 200, 200, 100)

    box1.add_text_frame("Start")
    box2.add_text_frame("End")

    # Add a bent connector (initial bounds are overwritten by the connection)
    conn = slide.shapes.add_connector(ShapeType.BENT_CONNECTOR3, 0, 0, 10, 10)

    # Connect right side of box1 (site 3) to left side of box2 (site 1)
    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

    prs.save("connected.pptx", SaveFormat.PPTX)

Bağlantı uç noktaları ayarlandığında (0, 0, 10, 10) yer tutucu sınırları add_connector‘ye iletilir ve göz ardı edilir; PowerPoint bağlayıcıyı ekli şekillere yeniden yönlendirir.
