解压.docx文件实现提取图片
前言
.docx文件其实也就是一个压缩文件,当我们将一个.docx文件直接解压后可以看到如下目录
其中我们要找的图片就在word/media目录内,如图
所以,要提取word内的图片就需要将.docx文件解压,再从media文件内取得图片,然后将解压后的文件删除
代码实现
import os import shutil import zipfile def get_pictures(word_path, result_path): """ 获取word内的所有图片 :param word_path: word文件 :param result_path: 结果目录,无需手动创建 :return: None or generator,None:word内没有图片,generator:每个图片的路径 """ tmp_path = f'{os.path.splitext(word_path)[0]}' # 拷贝源文件后重命名再解压 splitext = os.path.splitext(word_path) zip_path = shutil.copy(word_path, f'{splitext[0]}_new{splitext[1]}') with zipfile.ZipFile(zip_path, 'r') as f: for file in f.namelist(): f.extract(file, tmp_path) os.remove(zip_path) # 注:word图片在zip文件内的word/media目录下 pic_path = os.path.join(tmp_path, 'word/media') if not os.path.exists(pic_path): shutil.rmtree(tmp_path) return 'no pictures found' pictures = os.listdir(pic_path) if not os.path.exists(result_path): os.makedirs(result_path) for picture in pictures: # 根据word的文件名生成图片的名称 word_name = os.path.splitext(word_path)[0] if os.sep in word_name: new_name = word_name.split('\')[-1] else: new_name = word_name.split('/')[-1] picture_name = f'{new_name}_{picture}' shutil.copy(os.path.join(pic_path, picture), os.path.join(result_path, picture_name)) shutil.rmtree(tmp_path) return (os.path.join(result_path, pic) for pic in os.listdir(result_path))
word_path可以支持所有类型路径,如
p = r"C:UsersDesktop est小说.docx" p1 = "C:/Users/Desktop/test/小说.docx" p2 = "C:\Users\Desktop\test\小说.docx"
利用三方库docx实现图片提取(推荐)
import docx import os, re def get_pictures(word_path, result_path): """ 图片提取 :param word_path: word路径 :param result_path: 结果路径 :return: """ doc = docx.Document(word_path) dict_rel = doc.part._rels for rel in dict_rel: rel = dict_rel[rel] if "image" in rel.target_ref: if not os.path.exists(result_path): os.makedirs(result_path) img_name = re.findall("/(.*)", rel.target_ref)[0] word_name = os.path.splitext(word_path)[0] if os.sep in word_name: new_name = word_name.split('\')[-1] else: new_name = word_name.split('/')[-1] img_name = f'{new_name}_{img_name}' with open(f'{result_path}/{img_name}', "wb") as f: f.write(rel.target_part.blob)
