python—ｇｕｉ－计算图像像素两点间距离

代码：

import tkinter as tk
from tkinter import ttk


def create_gui():
    # 创建Tkinter窗口
    root = tk.Tk()
    # 设置窗口标题
    root.title("显示图片")

    # 图片文件路径
    image_path = 'path_to_your_image.jpg'
    # 加载图片
    img = load_image(image_path)

    # 创建标签，并将图片作为背景
    label = tk.Label(root, image=img)
    # 放置标签
    label.pack()

    # 开始Tkinter事件循环
    root.mainloop()

def calculate_distance(x1, y1, x2, y2):
    distance = ((x1 - x2) ** 2 + (y1 - y2) ** 2) ** 0.5
    label_distance.config(text=f"The distance is: {distance}")


def on_entry_change(event):
    x1 = float(entry_x1.get())
    y1 = float(entry_y1.get())
    x2 = float(entry_x2.get())
    y2 = float(entry_y2.get())
    calculate_distance(x1, y1, x2, y2)


root = tk.Tk()
root.title("Distance Calculator")

# 创建两组坐标输入框
frame_coords = tk.LabelFrame(root, text="Coordinates")
