Python 實(shí)現(xiàn)鼠標(biāo)拖動(dòng)截圖

此功能由3個(gè).py文件實(shí)現(xiàn)，分別為：test00.py、screenshot.py、py_tool.py；實(shí)現(xiàn)鼠標(biāo)附近局部放大，未截圖部分半透明，鼠標(biāo)控制鍵盤精準(zhǔn)截圖，鼠標(biāo)框選后自動(dòng)保存截圖，按下esc鍵退出截圖；

一、test00.py 用于測(cè)試

import tkinter as tk

from common import py_tool
from common.screenshot import Screenshot

scale = py_tool.get_screen_scale_rate()
py_tool.eliminate_scaling_interference()
top = tk.Tk()

Screenshot(top, scale)

top.mainloop()

二、screenshot.py 實(shí)現(xiàn)截圖

# coding:utf-8

import time
import tkinter as tk
import keyboard
from PIL import ImageGrab, ImageTk, Image

from common import py_tool


# 截圖類
class Screenshot:
    def __init__(self, top, scale):
        """---------------------------------------------------系統(tǒng)設(shè)置"""
        # 獲取屏幕縮放比例;
        self.scale = scale
        # 排除縮放干擾;
        py_tool.eliminate_scaling_interference()
        # 初始化關(guān)閉窗口標(biāo)志;
        self.win_close = 0
        "---------------------------------------------------初始窗口"
        # 最小化主窗口;
        top.iconify()
        # 實(shí)例化主窗口;
        self.top_screenshot = tk.Toplevel(top)

        self.img_screenshot = ImageGrab.grab(

        self.img_screenshot.save('test00.png')
        # 打開截圖;
        self.img_screenshot = Image.open('test00.png')
        "---------------------------------------------------窗口邊框"
        # 初始化邊框畫布邊框?qū)挾?
        self.canvas_frame_frame_width = 1 * self.scale
        # 創(chuàng)建上邊框畫布;

        canvas_frame_up.place(relx=0.5, rely=0, anchor=tk.CENTER)
