一、界面PdfZ.ui可参考之前的文章如何实现，程序代码如下：
二、main.py实现主要功能程序如下：
三、最后在主程序中加入以上子程序。
四、总结
PyQt是Qt框架的Python语言实现，是最强大的GUI库之一。PyQt提供了一个设计良好的窗口控件集合，具有更方便的操作性。学过VB的同学会知道，相比与VB的使用，在界面设计上元素更丰富。
本文就是基于PyQt5完成的pdf转word功能，先看界面：
一、界面PdfZ.ui可参考之前的文章如何实现，程序代码如下：from PyQt5 import QtCore, QtGui, QtWidgetsimport base64import osfrom return_png import img as retu # 引入img变量，赋别名为pdf_cfclass Ui_PdfZ(object): def setupUi(self, PdfZ):

= QtGui.QFont() font.setFamily("微软雅黑") font.setPointSize(12) font.setBold(True) font.setWeight(75) self.textEdit.setFont(font) self.textEdit.setObjectName("textEdit") self.label_5 =

self.label_4.setText(_translate("PdfZ", "页码选择(请勿输0)：")) self.label_5.setText(_translate("PdfZ", "到")) self.label_7.setText(_translate("PdfZ", "PDF预览"))二、main.py实现主要功能程序如下：class pdwwindow(QtWidgets.QWidget,Ui_PdfZ): def __init__(self): super(pdwwindow, self).__init__() self.setupUi(self) def re_back(self): self.close() def sctp(self): fileName, fileType = QtWidgets.QFileDialog.getOpenFileName(self, "选取文件", os.getcwd(),"自定义(*.pdf;*);;All Files(*)") self.f = str(fileName) self.p, self.s =self.f.split(".") try: if self.s == "pdf": # 打开文件 doc = fitz.open(self.f) # 读取一页 0代表第1页 page_one = doc.loadPage(0) # 将第一页转换为Pixmap page_pixmap = page_one.getPixmap() # 将Pixmap转换为QImage image_format = QImage.Format_RGBA8888 if page_pixmap.alpha else QImage.Format_RGB888 page_image = QImage(page_pixmap.samples, page_pixmap.width,page_pixmap.height, page_pixmap.stride, image_format) # width = page_image.width() # height = page_image.height() # QImage 转为QPixmap pix = QPixmap.fromImage(page_image) # 设置图片大小自适应标签 self.label_6.setScaledContents(True) # 给标签设置图像 self.label_6.setPixmap(pix) else: msg_box = QMessageBox(QMessageBox.Warning,"错误", "文件不是 pdf 文件，请重新选择！") msg_box.exec_() except Exception as e: pass def xzwj(self): docx_file = "{}_pdfZword.docx".format(self.p) str1 = self.textEdit.toPlainText() num1 = int(str1) str2 = self.textEdit_2.toPlainText() num2 = int(str2) if num1==num2: num1=num1-1 cv = Converter(self.f) cv.convert(docx_file, start=num1, end=num2) cv.close() root = tkinter.Tk() root.withdraw() tkinter.messagebox.showinfo("提示", "成功下载到源文件所在文件夹")说明如下：
(1) def sctp(self): 其中的sctp为按钮的objectName属性名字；def xzwj(self):其中的xzwj为按钮的objectName属性名字；
(2) 可通过点击按钮实现本地文件上传；
fileName, fileType = QtWidgets. QFileDialog.getOpenFileName(self, "选取文件", os.getcwd(), "自定义(*.jpg;*.png;*.jpeg;*);;All Files(*)")(3) 增加了防错功能，当上传的文档格式不是pdf时，将不执行程序，同时提示错误；
(4) 将pdf第一页转为图片，并用label组件显示；
(5) 在def xzwj(self):程序中可实现按页数提取word；
(6) 借助converter模块实现转化word。
三、最后在主程序中加入以上子程序。if __name__ =="__main__": import sys app = QtWidgets.QApplication(sys.argv) win = mywindow() pw = pdwwindow() win.show() win.pdf_word.clicked.connect(win.pic_main) win.pdf_word.clicked.connect(pw.show) pw.Reback.clicked.connect(pw.re_back) pw.Reback.clicked.connect(win.show) pw.scwd.clicked.connect(pw.sctp) pw.xzwd.clicked.connect(pw.xzwj) sys.exit(app.exec_())四、总结本文介绍的pdf转word功能还有一些待完善地方，例如可增加预览功能，实现每页预览。当然我们可以在后续阶段逐渐完善。
