Python实现提取或替换PPT中文本与图片的示例代码
虚坏叔叔 人气:0提取保存ppt中的图片
如何从pptx中提取所有图片?用python-pptx轻松实现图片提取
从指定的文件夹中,对所有pptx(注意不是ppt,因为两者文档格式不同)进行图片提取。
提取出来的图片,以图片原有名称作为文件名,如果遇到文件名有相同,则在文件名后随机加上数字,保存位置为程序中设定的targetPath,如果该目录不存在的话,则会先创建一个。
示例代码
import os import re,random from pptx import Presentation # coding=gbkimport osimport refrom pptx import Presentationimport random class ExtractPPTXimg(): def __init__(self,params): self.errFlag = False self.msg = "" self.sourcePath = params["sourcePath"] if not os.path.exists(self.sourcePath): self.errFlag = True self.msg = "源文件夹不存在!" self.targetPath = params["targetPath"] if not os.path.exists(self.targetPath): os.makedirs(self.targetPath) self.run() def run(self): if self.errFlag: print(self.msg) return for file in os.listdir(self.sourcePath): if not file[-4:] == "pptx": continue if re.findall("^~",file): continue # 提取图片 self.extractImg(file) # 保存pptx中的图片 def extractImg(self,file): fileName,expadName = os.path.splitext(file) prs = Presentation(os.path.join(self.sourcePath,file)) for slide in prs.slides: for shape in slide.shapes: try: if "image" in shape.image.content_type: imgName = shape.image.filename newPath = os.path.join(self.targetPath, fileName) if not os.path.exists(newPath): os.makedirs(newPath) newFile = os.path.join(newPath, imgName) self.saveImage(newFile,shape.image.blob) except: continue # 保存图片 def saveImage(self,newFile,blob): if os.path.exists(newFile): fileName, expadName = os.path.splitext(newFile) newFile = "{}-{}{}".format(fileName,random.randint(1,1000),expadName) with open(newFile, "wb") as f: f.write(blob) print("已保存{}".format(newFile)) def __str__(self): return self.msg if __name__ == '__main__': # 要进行提取的pptx的所在目录 "targetPath":r"K:\伍德春原创视频\自动化\2020-11-10\img", # 提取后的txt文件要保存到的目录 params = { "sourcePath":r"D:\自动化", "targetPath":r"D:\自动化\img",} newobj = ExtractPPTXimg(params)
替换ppt模板的文本
我要做的就是:利用python自动控制ppt,动态修改我们指定的变量参数,
把组合出来的幻灯片保存为一张张的图片,然后在这个基础上加入批量化!
