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 。

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imgPathsubImgPath = 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:continueimgName = 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！")returnif 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imgPathsubImgPath = 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:continueimgName = 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:continueQMessageBox.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：【word中的图片如何保存为jpg格式 把word导出成图片的流程】
