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, 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_PdfZobject): def setupUiself, PdfZ): tmp = open'return.png', 'wb') # 创建临时的文件 tmp.writebase64.b64decoderetu)) # 把这个one图片解码出来，写入文件中去。 tmp.close) PdfZ.setObjectName"PdfZ") PdfZ.resize1400, 814) PdfZ.setMinimumSizeQtCore.QSize1400, 814))

二、main.py实现主要功能程序如下：
class pdwwindowQtWidgets.QWidget,Ui_PdfZ):
def __init__self):
superpdwwindow, self).__init__)
self.setupUiself)
def re_backself):
self.close)
def sctpself):
fileName, fileType = QtWidgets.QFileDialog.getOpenFileNameself, "选取文件", os.getcwd),"自定义*.pdf;*);;All Files*)")
self.f = strfileName)
self.p, self.s =self.f.split".")
try:
if self.s == "pdf":
# 打开文件
doc = fitz.openself.f)
# 读取一页 0代表第1页
page_one = doc.loadPage0)
# 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 = QImagepage_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.fromImagepage_image)
# 设置图片大小自适应标签
self.label_6.setScaledContentsTrue)
# 给标签设置图像
self.label_6.setPixmappix)
else:
msg_box = QMessageBoxQMessageBox.Warning,"错误", "文件不是 pdf 文件，请重新选择！")
msg_box.exec_)
except Exception as e:
pass
def xzwjself):
docx_file = "{}_pdfZword.docx".formatself.p)
str1 = self.textEdit.toPlainText)
num1 = intstr1)
str2 = self.textEdit_2.toPlainText)
num2 = intstr2)
if num1==num2:
num1=num1-1
cv = Converterself.f)
cv.convertdocx_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 sctpself): 其中的sctp为按钮的objectName属性名字；def xzwjself):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.getOpenFileNameself, "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 xzwjself):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.QApplicationsys.argv) win = mywindow) pw = pdwwindow) win.show) win.pdf_word.clicked.connectwin.pic_main) win.pdf_word.clicked.connectpw.show) pw.Reback.clicked.connectpw.re_back) pw.Reback.clicked.connectwin.show) pw.scwd.clicked.connectpw.sctp) pw.xzwd.clicked.connectpw.xzwj) sys.exitapp.exec_))
