python如何将多张图片批量插入PPT中?

• 第一步 获取图片
• 第二步 生成PPT

第一步 获取图片

批量获取第一类图片

import shutil
import easygui as g
import os

# 检查 ./SourceImage 目录是否存在，不存在则创建它
if (not (os.path.exists( r"C:\Users\Public\Documents\Word" ))):
    os.mkdir( r"C:\Users\Public\Documents\Word" )
if (not (os.path.exists( r"C:\Users\Public\Documents\Word1" ))):
    os.mkdir( r"C:\Users\Public\Documents\Word1" )
if (not (os.path.exists( r"C:\Users\Public\Documents\res" ))):
    os.mkdir( r"C:\Users\Public\Documents\res" )
path = g.diropenbox()
g = os.walk(path)
for path, dir_list, file_list in g:
    for file_name in file_list:
        if "WholeCoreViewer.png" in os.path.join(path, file_name):
            picpath2 = os.path.join(path, file_name)
            print("正在复制... %s " % picpath2)
            new_name = picpath2.split('\\')
            new_name2 = new_name[-1]
            # print(new_name2)

            shutil.copy(picpath2, os.path.join(r'C:\Users\Public\Documents\Word1', new_name2))

批量获取第二类图片(第二类图需要压缩)

                    a.append(f)

            path_name3 =path_name2.replace(". ", "_")
            # print(os.path.join(path, file_name))
            picpath = os.path.join(path, file_name)
            file_name = "\\%s_%s" % (path_name3, a[0])
            picpath2 = os.path.join(path, copypath + file_name)
            picpath3 =picpath2.replace(".JPG", ".JPEG")
            print("正在复制... %s " % picpath3)
            shutil.copy(picpath, picpath3)

第二步 生成PPT

from pptx.enum.text import PP_ALIGN

import os
from pptx import Presentation

# 设置路径

os.chdir(work_path)

# 实例化 ppt 文档对象
prs = Presentation()

prs.slide_height = Inches(9)

# 插入幻灯片
rootdir = r'C:\Users\Public\Documents\Word'

list = os.listdir(rootdir)
list1 = os.listdir(rootdir1)  # 列出文件夹下所有的目录与文件
print(list)  # ['喷碳.jpeg', '岩心烘箱.jpeg', '显微镜.jpeg']

# 添加图片
i = 0
j = 0
while i < len(list1):
    img_name1 = rootdir + '\\' + list[i]
    img_name2 = rootdir1 + '\\' + list1[j]
    print(img_name1)

    tf = textbox.text_frame
    para = tf.add_paragraph()    # 添加段落
    para.text = "%s" % list1[i]
    para.alignment = PP_ALIGN.LEFT  # 居中
    ## 设置字体

    font.size = Pt(20)    # 大小
    font.name = 'Arial'    # 字体
    font.color.rgb = RGBColor(255, 0, 0)  # 红色

    i += 1
    j += 1

# 保存 ppt
prs.save('result.pptx')
