浏览，打开 PDF 文件，在第 1 页添加图章，然后另存为新文件 python

Question

我将这些代码行 browse/open 成一个 pdf，将 stamp/image 添加到第 1 页，然后将其另存为新文件。但是当我运行代码时，它没有保存新的 pdf 文件。非常感谢任何帮助，我是 python.

的新手

import tkinter
import fitz
from tkinter import messagebox
from tkinter import filedialog


main_win = tkinter.Tk()
main_win.geometry("500x500")
main_win.sourceFolder = ''
main_win.sourceFile = ''
def chooseDir():
    main_win.sourceFolder =  filedialog.askdirectory(parent=main_win, initialdir= "/", title='Please select a directory')

b_chooseDir = tkinter.Button(main_win, text = "Chose Folder", width = 20, height = 3, command = chooseDir)
b_chooseDir.place(x = 50,y = 50)
b_chooseDir.width = 100


def chooseFile():
    main_win.sourceFile = filedialog.askopenfilename(parent=main_win, initialdir= "/", title='Please select a directory')

def convertFile():
    dst_pdf_filename = 'destination.pdf'
    img_filename = 'hillsborough county stamp.png'
  
    img_rect = fitz.Rect(55, 28, 180, 390)
    
    page = document[0]
    page.insertImage(img_rect, filename=img_filename)
  
    document.save(dst_pdf_filename)
    document.close()
    
b_chooseFile = tkinter.Button(main_win, text = "Chose File", width = 20, height = 3, command = chooseFile)
b_chooseFile.place(x = 250,y = 50)
b_chooseFile.width = 100

b_convertFile = tkinter.Button(main_win, text = "Convert File", width = 20, height = 3, command = convertFile)
b_convertFile.place(x = 250,y = 200)
b_convertfile.width = 100


main_win.mainloop()
print(main_win.sourceFolder)
print(main_win.sourceFile )

据我了解，您想在源文件 main_win.sourceFile 中添加邮票图像并将其保存到新文件 dst_pdf_filename:

def convertFile():
    if main_win.sourceFile:
        dst_pdf_filename = 'destination.pdf'
        img_filename = 'hillsborough county stamp.png'

        img_rect = fitz.Rect(55, 28, 180, 390)

        document = fitz.open(main_win.sourceFile) # open source file
        page = document[0]
        page.insertImage(img_rect, filename=img_filename)

        document.save(dst_pdf_filename)
        document.close()
