如何用python-pptx识别PPT中文本框的出入站连接线？

1. 如何判断PPT中特定文本框是否存在入站或出站连接线？
2. 使用python-pptx库可以获取PPT中的文本框和形状，也能区分文本框与线条，但找不到解析连接关系的相关文档，无法建立文本框与线条的关联。

实现代码 #

from pptx import Presentation
from pptx.enum.shapes import MSO_SHAPE_TYPE

# ========================================================
# 加载演示文稿
# ========================================================
lobj_presentation = Presentation(self.pptx_file_path)

# ========================================================
# 获取幻灯片总数
# ========================================================
total_slides = len(lobj_presentation.slides)

llst_slide_content = []

i = 0
for slide in range(total_slides):
    # 获取当前幻灯片的形状总数
    total_shapes = len(lobj_presentation.slides[slide].shapes)

    llst_shapes = []

    for shape in range(total_shapes):
        i += 1
        lobj_shape = lobj_presentation.slides[slide].shapes[shape]
        shape_content = dict()
        shape_content['Id'] = i
        shape_content['Slide_No'] = int(slide)
        shape_content['Shape_Id'] = lobj_shape.shape_id
        shape_content['Shape_Type_Id'] = lobj_shape.shape_type

        if lobj_shape.shape_type == MSO_SHAPE_TYPE.TEXT_BOX:
            shape_content['Shape_Type'] = 'Text_Box'

        elif lobj_shape.shape_type == MSO_SHAPE_TYPE.LINE:
            shape_content['Shape_Type'] = 'Line'

        if lobj_shape.has_text_frame:
            shape_content['Shape_Text'] = lobj_shape.text

        else:
            shape_content['Shape_Text'] = ''

        shape_content['Left'] = int(lobj_shape.left)
        shape_content['Top'] = int(lobj_shape.top)
        shape_content['Width'] = int(lobj_shape.width)
        shape_content['Height'] = int(lobj_shape.height)

        shape_content['X1'] = int(lobj_shape.left)
        shape_content['Y1'] = int(lobj_shape.top)
        shape_content['X2'] = int(lobj_shape.left) + int(lobj_shape.width)
        shape_content['Y2'] = int(lobj_shape.top) + int(lobj_shape.height)
        shape_content['Line_Index'] = -1

        llst_shapes.append(shape_content)

    llst_slide_content.append(llst_shapes)

代码输出 #
