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'

# 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

from pptx import Presentation
# 设置路径

prs = Presentation()
# ＃ 设置幻灯片尺寸，16:9

# 插入幻灯片

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']
print(list1) # ['WYD1#_1_1_100cm.WholeCoreViewer.png']
# 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)
print(img_name2)
blank_slide = prs.slide_layouts[6]
slide_1 = prs.slides.add_slide( blank_slide )
a = slide_1.shapes.add_picture( image_file=img_name1,
left=Inches(0.1),
top=Inches(1.9),
width=Inches(8.2),
height=Inches(5.5))
a.rotation = (90.00) # 将图片旋转90度
slide_1.shapes.add_picture( image_file=img_name2,
left=Inches( 8),
top=Inches( 0.8 ),
width=Inches( 5.5 ),
height=Inches( 8.2) )
textbox= slide_1.shapes.add_textbox(left=Inches(8),
top=Inches(0),

height=Inches(1))
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 = para.font
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')
