前言

开发这个软件还得从最早是21年说起。当时正值6月毕业答辩，学校让上传毕业资料。其中包括论文，开题报告，以及中期报告，外文翻译等，要求资料整合到一个word中。当时整合文档时光修改格式就难倒了一大批同学，很多学生的office还不是特别熟悉，修改格式更是难上加难。所以大家就想了一个简单的方法，将这些文档的PDF文件拼接到一起就好，只用修改页码。PDF拼接合并不会修改文本格式的。这个想法虽然是好的，但网上很多PDF拼接软件都是收费的。所以当时有Python基础的我就想到的自动化办公或许可以解决这个问题，查阅了资料后，发现果然可以用Python实现。所以当时用了大概4小时时间就写好了PDF拼接合并软件，包括UI设计等。但是当时毕业季挺忙的，就没发布出来，只是同学间使用。
现在22年了，都毕业一年了。刚入职比亚迪，新员工的电脑还没审批下来，所以没什么工作安排，就在办公室熟悉项目，所以就利用工作的空闲时间将这个软件开发完整。

一、软件具备什么功能？

PDF拆分
PDF合并
PDF转Word
PDF加密
PDF解密
在这里插入图片描述
Word转PDF功能纯属胡扯，WPS免费就搞定了。

二、开发步骤

2.1.引入库

代码如下（示例）：

import os,ast
import choose,cut,merge,pdfcvword,wordcvpdf,encypdf,decr # 导入ui界面的py文件
from PyQt5 import QtWidgets
from PyPDF2 import PdfFileReader,PdfFileWriter
import tkinter as tk
from tkinter import filedialog
# python3.6安装pdf2docx出错时可以先试试安装pymupdf==1.19.3。安装成功后再安装pdf2docx
from pdf2docx import Converter

2.2.PDF拆分功能设计

该功能是搭配UI界面去设计的，所以必要时要配合UI界面去看。
在这里插入图片描述

拆分功能代码如下：

#***********************************  拆分功能  **********************************************#
# 选择拆分文件
def choose_cut_filepath():
    root = tk.Tk()
    root.withdraw()
    f_path=filedialog.askopenfilename()
    cut_ui.lineEdit_2.setText(f_path)
# PDF页码读取
def read_page():
    try:
        path = cut_ui.lineEdit_2.text()
        pdf_reader = PdfFileReader(path)
        num = pdf_reader.getNumPages()
        cut_ui.lineEdit_3.setText(str(num))
    except Exception as e:
        cut_ui.lineEdit_3.setText(str(e))
# 拆分输出文件路径选择
def select_cut_outputh():
    global cut_path
    root = tk.Tk()
    root.withdraw()
    f_path = filedialog.askdirectory()
    cut_ui.lineEdit.setText(f_path)
    cut_path=f_path
# PDF拆分
def cut_pdf():
    try:
        global cut_path
        num1=cut_ui.lineEdit_4.text()
        num1=ast.literal_eval(num1)
        path1=os.path.join(cut_path,'拆分1.pdf')
        path2 = os.path.join(cut_path,'拆分2.pdf')
        path=cut_ui.lineEdit_2.text()
        pdf_reader = PdfFileReader(path)
        pdf_writer1 = PdfFileWriter()
        pdf_writer2 = PdfFileWriter()
        num2 = pdf_reader.getNumPages()
        if num1<num2:
            for page1 in range(0,num1):
                pdf_writer1.addPage(pdf_reader.getPage(page1))
            with open(path1,'wb') as out:
                pdf_writer1.write(out)
            for page2 in range(num1, num2):
                pdf_writer2.addPage(pdf_reader.getPage(page2))
            with open(path2, 'wb') as out:
                pdf_writer2.write(out)
            cut_ui.lineEdit_5.setText(cut_path)
        else:
            cut_ui.lineEdit_5.setText('拆分页码不符合要求')
    except Exception as e:
        cut_ui.lineEdit_5.setText(str(e))

主程序里的UI调用代码如下

 # 拆分窗口
   	cutwindow=  QtWidgets.QWidget()
    cut_ui=cut.Ui_Form()
    cut_ui.setupUi(cutwindow)
    cut_ui.pushButton.clicked.connect(choose_cut_filepath)
    cut_ui.pushButton_2.clicked.connect(read_page)
    cut_ui.pushButton_3.clicked.connect(cut_pdf)
    cut_ui.pushButton_4.clicked.connect(back_choosewindow)
    cut_ui.pushButton_5.clicked.connect(select_cut_outputh)

2.3 PDF合并

            merge_ui.lineEdit_2.setText(str(output))
    except Exception as e:
