基於PyQt5完成pdf轉word功能
2022-06-09 22:00:24
PyQt是Qt框架的Python語言實現，是最強大的GUI庫之一。PyQt提供了一個設計良好的視窗控制元件集合，具有更方便的操作性。學過VB的同學會知道，相比與VB的使用，在介面設計上元素更豐富。
本文就是基於PyQt5完成的pdf轉word功能，先看介面：
一、介面PdfZ.ui可參考之前的文章如何實現，程式程式碼如下：
from PyQt5 import QtCore, QtGui, QtWidgets
import base64
import os
from return_png import img as retu # 引入img變數，賦別名為pdf_cf
class Ui_PdfZ(object):
def setupUi(self, PdfZ):
tmp = open('return.png', 'wb') # 建立臨時的檔案
tmp.write(base64.b64decode(retu)) # 把這個one圖片解碼出來，寫入檔案中去。
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))

palette.setBrush(QtGui.QPalette.Active, QtGui.QPalette.Window, brush)

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", "+ 上傳檔案"))
self.label_2.setText(_translate("PdfZ", "上傳檔案至此"))
self.label_3.setText(_translate("PdfZ", "操作"))
self.xzwd.setText(_translate("PdfZ", "開始轉換"))
self.label_4.setText(_translate("PdfZ", "頁碼選擇(請勿輸0)："))
self.label_5.setText(_translate("PdfZ", "到"))
self.label_7.setText(_translate("PdfZ", "PDF預覽"))二、main.py實現主要功能程式如下：
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, "選取檔案", os.getcwd(),"自定義(*.pdf;*);;All Files(*)")
self.f = str(fileName)
self.p, self.s =self.f.split(".")
try:
if self.s == "pdf":
# 開啟檔案
doc = fitz.open(self.f)
# 讀取一頁 0代表第1頁
page_one = doc.loadPage(0)
# 將第一頁轉換為Pixmap
page_pixmap = page_one.getPixmap()
# 將Pixmap轉換為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 轉為QPixmap
pix = QPixmap.fromImage(page_image)
# 設定圖片大小自適應標籤
self.label_6.setScaledContents(True)
# 給標籤設定影象
self.label_6.setPixmap(pix)
else:
msg_box = QMessageBox(QMessageBox.Warning,"錯誤", "檔案不是 pdf 檔案，請重新選擇！")
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", "成功下載到原始檔所在資料夾")說明如下：
(1) def sctp(self): 其中的sctp為按鈕的objectName屬性名字；def xzwj(self):其中的xzwj為按鈕的objectName屬性名字；
(2) 可通過點選按鈕實現本地檔案上傳；
fileName, fileType = QtWidgets. QFileDialog.getOpenFileName(self, "選取檔案", os.getcwd(), "自定義(*.jpg;*.png;*.jpeg;*);;All Files(*)")
(3) 增加了防錯功能，當上傳的檔案格式不是pdf時，將不執行程式，同時提示錯誤；
(4) 將pdf第一頁轉為圖片，並用label元件顯示；
(5) 在def xzwj(self):程式中可實現按頁數提取word；
(6) 藉助converter模組實現轉化word。
三、最後在主程式中加入以上子程式。
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_())四、總結
本文介紹的pdf轉word功能還有一些待完善地方，例如可增加預覽功能，實現每頁預覽。當然我們可以在後續階段逐漸完善。
