政采云上传图片大小要求最小为800*800，每次上传商品都是心酸的过程哈， 随便瞎写了一个，有需要自取，自己日常使用
——————————————————–
代码如下：
import tkinter as tk
from tkinter import ttk, filedialog, messagebox
from PIL import Image
import os
from tkinterdnd2 import DND_FILES, TkinterDnD
class ImageUpscalerApp:

# 设置一个足够大的初始窗口尺寸，比如 900×700
self.root.geometry(“900×700″)
self.file_paths = []
self.output_dir = tk.StringVar()
self.setup_ui()
