word中的图片如何保存为jpg格式（把word导出成图片的流程）

由于工作中需要从大量docx文档中提出图片，于是到网上搜索，找了一大堆都是分析xml文件并提取的，太过于复杂，实际上有更简单的方法，我们需要用到python-docx这个第三方库，但该库并未开发提取图片功能，不过可以通过其他方法出得到图片数据并保存为图片。

软件界面

下面这段代码是核心：

    for file in os.listdir(filePath):        try:            #跳过非docx文件            if ".docx" not in file:                continue            # 创建imgPath            subImgPath = imgPath + re.sub(".docx","",file)            if not os.path.exists(subImgPath):                os.makedirs(subImgPath)            doc = docx.Document(filePath + file)        #打开文件            for rel in doc.part._rels:                rel = doc.part._rels[rel]               #获得资源                if "image" not in rel.target_ref:                    continue                imgName = re.findall("/(.*)",rel.target_ref)[0]                with open(subImgPath + "/" + imgName,"wb") as f:                    f.write(rel.target_part.blob)            UI.currentFile.setText("当前文件：" + imgName)        except:            continue

后来经过改进，使用PyQt5制作了界面，下面为源代码：

import docx,re,os,sys,ui_imgExtractfrom PyQt5.QtWidgets import QApplication,QMainWindow,QWidget,QMessageBoxfrom PyQt5.Qt import QFileDialogdef run():    filePath = UI.filePath.text()    imgPath = UI.imgPath.text()    if not os.path.exists(filePath):        QMessageBox.about(main, "错误", "请选择docx文件目录！")        return    if not os.path.exists(imgPath):        os.makedirs(imgPath)    for file in os.listdir(filePath):        try:            #跳过非docx文件            if ".docx" not in file:                continue            # 创建imgPath            subImgPath = imgPath + re.sub(".docx","",file)            if not os.path.exists(subImgPath):                os.makedirs(subImgPath)            doc = docx.Document(filePath + file)        #打开文件            for rel in doc.part._rels:                rel = doc.part._rels[rel]               #获得资源                if "image" not in rel.target_ref:                    continue                imgName = re.findall("/(.*)",rel.target_ref)[0]                with open(subImgPath + "/" + imgName,"wb") as f:                    f.write(rel.target_part.blob)            UI.currentFile.setText("当前文件：" + imgName)        except:            continue    QMessageBox.about(main, "完成", "图片提取已完成！")def init():    UI.btnRun.clicked.connect(run)      #绑定开始提取按钮    UI.btnFilePath.clicked.connect(choiceFileDir)  # 绑定选择docx文件目录    UI.btnImgPath.clicked.connect(choiceImgOutPutDir)    #绑定选择图片保存目录    # docx文件默认目录    UI.filePath.setText(os.getcwd())    #默认输出目录    if not os.path.exists(os.getcwd() + "img\"):        os.makedirs(os.getcwd() + "img\")    UI.imgPath.setText(os.getcwd() + "img\")#选择docx文件目录def choiceFileDir():    dir = QFileDialog.getExistingDirectory(main, "选择docx文件目录", os.getcwd())    UI.filePath.setText(dir + "/")#选择图片保存目录def choiceImgOutPutDir():    dir = QFileDialog.getExistingDirectory(main, "选择输出目录", os.getcwd())    UI.imgPath.setText(dir + "/")if __name__ == "__main__":    app = QApplication(sys.argv)    main = QWidget()    UI = ui_imgExtract.Ui_Form()    UI.setupUi(main)    main.show()    init()    sys.exit(app.exec_())

下面是界面文件ui_imgExtract.py：
