这篇文章给大家分享的是“yQt5实现pdf转word功能怎样做，过程是什么”，对大家学习和理解有一定的参考价值和帮助，有这方面学习需要的朋友，接下来就跟随小编一起学习一下吧。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, QtWidgets
import base64
import os
from 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))

self.label_6.setLineWidth(1)
self.label_6.setMidLineWidth(0)
self.label_6.setText("")
self.label_6.setObjectName("label_6")
self.retranslateUi(PdfZ)
QtCore.QMetaObject.connectSlotsByName(PdfZ)
os.remove("return.png")
def retranslateUi(self, PdfZ):
_translate = QtCore.QCoreApplication.translate
PdfZ.setWindowTitle(_translate("PdfZ", "PDFZWORD"))
self.Reback.setText(_translate("PdfZ", "..."))
self.label.setText(_translate("PdfZ", "PDFZWORD"))
self.scwd.setText(_translate("PdfZ", "+ 上传文档"))
self.label_2.setText(_translate("PdfZ", "上传文档至此"))
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_())
