基于PyQt5完成pdf转word功能基于PyQt5完成pdf转word功能

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：

"开始转换"))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Pixmappage_pixmap = page_one.getPixmap()# 将Pixmap转换为QImageimage_format = QImage.Format_RGBA8888 if page_pixmap.alpha else QImage.Format_RGB888page_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QPixmappix = 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:passdef 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=num1-1cv = 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；
【基于PyQt5完成pdf转word功能】(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 sysapp = 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。
