基于PyQt5如何完成pdf转word功能

本篇内容介绍了“基于PyQt5如何完成pdf转word功能”的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

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。

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_cf class Ui_PdfZ(object):    def setupUi(self, PdfZ):        tmp = open('return.png', 'wb')  # 创建临时的文件        tmp.write(base64.b64decode(retu))  # 把这个one图片解码出来，写入文件中去。        tmp.close()        PdfZ.setObjectName("PdfZ")        PdfZ.resize(1400, 814)        PdfZ.setMinimumSize(QtCore.QSize(1400, 814))        PdfZ.setMaximumSize(QtCore.QSize(1400, 814))        palette = QtGui.QPalette()        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Active, QtGui.QPalette.Base, brush)        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Active, QtGui.QPalette.Window, brush)        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Inactive, QtGui.QPalette.Base, brush)        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Inactive, QtGui.QPalette.Window, brush)        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.Base, brush)        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.Window, brush)        PdfZ.setPalette(palette)        self.Reback = QtWidgets.QToolButton(PdfZ)        self.Reback.setGeometry(QtCore.QRect(10, 10, 51, 41))        palette = QtGui.QPalette()        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Active, QtGui.QPalette.Button, brush)        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Active, QtGui.QPalette.ToolTipBase, brush)        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Inactive, QtGui.QPalette.Button, brush)        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Inactive, QtGui.QPalette.ToolTipBase, brush)        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.Button, brush)        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.ToolTipBase, brush)        self.Reback.setPalette(palette)        icon = QtGui.QIcon()        icon.addPixmap(QtGui.QPixmap("return.png"), QtGui.QIcon.Normal, QtGui.QIcon.Off)        self.Reback.setIcon(icon)        self.Reback.setIconSize(QtCore.QSize(100, 100))        self.Reback.setAutoRaise(True)        self.Reback.setObjectName("Reback")        self.label = QtWidgets.QLabel(PdfZ)        self.label.setGeometry(QtCore.QRect(88, 8, 171, 41))        font = QtGui.QFont()        font.setFamily("微软雅黑")        font.setPointSize(16)        font.setBold(True)        font.setWeight(75)        self.label.setFont(font)        self.label.setObjectName("label")        self.frame = QtWidgets.QFrame(PdfZ)        self.frame.setGeometry(QtCore.QRect(20, 60, 1351, 161))        palette = QtGui.QPalette()        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Active, QtGui.QPalette.Base, brush)        brush = QtGui.QBrush(QtGui.QColor(245, 255, 250))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Active, QtGui.QPalette.Window, brush)        brush = QtGui.QBrush(QtGui.QColor(255, 255, 255))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Inactive, QtGui.QPalette.Base, brush)        brush = QtGui.QBrush(QtGui.QColor(245, 255, 250))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Inactive, QtGui.QPalette.Window, brush)        brush = QtGui.QBrush(QtGui.QColor(245, 255, 250))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.Base, brush)        brush = QtGui.QBrush(QtGui.QColor(245, 255, 250))        brush.setStyle(QtCore.Qt.SolidPattern)        palette.setBrush(QtGui.QPalette.Disabled, QtGui.QPalette.Window, brush)        self.frame.setPalette(palette)        self.frame.setAutoFillBackground(True)        self.frame.setFrameShape(QtWidgets.QFrame.Box)        self.frame.setFrameShadow(QtWidgets.QFrame.Plain)        self.frame.setLineWidth(1)        self.frame.setMidLineWidth(0)

传文档至此"))        self.label_3.setText(_translate("PdfZ", "操作"))        self.xzwd.setText(_translate("PdfZ", "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_())
