python如何将多张图片批量插入PPT中?
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)
import shutil
import easygui as g
import base64
import io
import os
from PIL import Image
from PIL import ImageFile
copypath = r'C:\Users\Public\Documents\Word'

if ".JPG" in os.path.join(path, file_name):
# print(path)
# print( file_list )
for i in file_list:
if ".JPG" in i:
f = i
a.append(f)
path_name1 =path.replace("\\", "_")
path_name2 = path_name1.replace(":", "_")
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)
# 压缩图片文件

# 添加图片
i = 0
j = 0
while i < len(list1):

blank_slide = prs.slide_layouts[6]
slide_1 = prs.slides.add_slide( blank_slide )

left=Inches(0.1),

width=Inches(8.2),

## 设置字体
font = para.font

i += 1

# 保存 ppt
prs.save('result.pptx')
