学生正在学习图像的编码与压缩，记录一下这个python小程序，给他们提供一下帮助。需要用到PIL库，记得安装：
pip install pillow
import tkinter as tk
from tkinter import filedialog
from PIL import Image
import tkinter.messagebox as messageboxclass ImageCompressor:def __init__(self, window):self.window = windowself.window.title("图片压缩工具By ZYX 2023")self.source_path = tk.StringVar()self.output_path = tk.StringVar()frame1 = tk.Frame(window)frame1.pack(padx=5, pady=5)lbl_source = tk.Label(frame1, text="原始图片路径:")lbl_source.pack(side=tk.LEFT)entry_source = tk.Entry(frame1,textvariable=self.source_path, width=40)entry_source.pack(side=tk.LEFT)btn_source =tk.Button(frame1, text="打开", command=self.open_source_image)btn_source.pack(side=tk.LEFT)frame2 = tk.Frame(window)frame2.pack(padx=5, pady=5)lbl_output = tk.Label(frame2, text="输出图片路径:")lbl_output.pack(side=tk.LEFT)entry_output = tk.Entry(frame2,textvariable=self.output_path, width=40)entry_output.pack(side=tk.LEFT)btn_output =tk.Button(frame2, text="保存", command=self.save_output_image)btn_output.pack(side=tk.LEFT)quality_label = tk.Label(window, text='质量（1-95）:')quality_label.pack(pady=5)self.quality_slider = tk.Scale(window, from_=1, to=95,length=400,tickinterval=19,orient='horizontal', resolution=1)self.quality_slider.set(80)self.quality_slider.pack()btn_compress =tk.Button(window, text="开始压缩", command=self.compress_image)btn_compress.pack(pady=10)def open_source_image(self):file_path = filedialog.askopenfilename()self.source_path.set(file_path)def save_output_image(self):file_path = filedialog.asksaveasfilename(defaultextension=".jpg")self.output_path.set(file_path)def compress_image(self):try:img = Image.open(self.source_path.get())img.save(self.output_path.get(), "JPEG", quality=self.quality_slider.get())messagebox.showinfo("成功", "图片压缩成功!")except Exception as e:messagebox.showerror("失败", f"压缩过程中发生错误：{e}")if __name__ == '__main__':window = tk.Tk()app = ImageCompressor(window)window.mainloop()
