如何检测 pptx 幻灯片中所有现有的 PNG/JPG 图像，然后使用 python pptx 处理它们的 size/layout？

Question

我有一个 PowerPoint 演示文稿，其中包含数十张仅标题格式但带有图像的幻灯片 objects。 objects 通常是 (1) 一个大图形图像，(2) 一个小图例图像，以及 (3) 另一个小图例图像。图像通常过大，超过幻灯片尺寸或相互重叠。我想使用以下步骤清理幻灯片图像：

打开已知文件名的现有 pptx （已经知道如何操作）
从幻灯片 2 开始
查找幻灯片中的所有图像。确定哪个是最左边的图像。 （我卡在这里了。）
最左边的图像是 (1) 图形图像。调整它直到达到 6.4" 的高度或 13" 的宽度。将其与最左边缘和最上边缘对齐（触摸幻灯片标题文本框）
如果图表图像的高度为 6.4"，请将图例图像移动到图表图像的右边缘附近。对齐它们的上边缘。
如果图形图像的宽度为 13"，请将图例图像移动到图形图像的底部边缘附近。对齐它们的右边缘。
重复直到最后一张幻灯片
跳过第 header 部分布局的幻灯片。

更新：到目前为止，这是我的代码

from pptx import Presentation
import glob
from pptx.util import Inches
from pptx.enum.text import PP_ALIGN

f = open('C:\Users\7188712\Desktop\Script Validation\XTI\Blade2T_XTI (Tag1.7.1.40).pptx', 'rb')
prs = Presentation(f)
slides = prs.slides
for slide in prs.slides:
    print('\nslide number ', slides.index(slide)+1, slide.shapes.title.text)
    for shape in slide.shapes:
        #if shape.shape_type == 13:  #Type 13 means PICTURE type
            #print("id: %s, height: %s, width: %s, ext: %s"% \
             #     (shape.shape_id, round(shape.height.inches,2), round(shape.width.inches,2), shape.image.ext)) 
         print('id: %s, height: %s, width: %s'% \
                (shape.shape_id, round(shape.height.inches,2), round(shape.width.inches,2)), shape.shape_type, shape.name) 

         if shape.name == 'Title 1':
            shape.alignment = PP_ALIGN.LEFT

终于！
