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_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 =

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_())
