用过pyautogui的同学应该都知道，locateOnScreen可以传入一张图片与当前屏幕（截屏）进行匹配，但是我的需求是能基于已经截屏的图片来进行图像定位，看了pyautogui的源码没有相关的接口，突发奇想自己定义一个。

首先，参考locateOnScreen的源码

/usr/local/lib/python3.9/site-packages/pyautogui/__init__.py

    @raisePyAutoGUIImageNotFoundException
    def locateOnScreen(*args, **kwargs):
        return pyscreeze.locateOnScreen(*args, **kwargs)

/usr/local/lib/python3.9/site-packages/pyscreeze/__init__.py

def locateOnScreen(image, minSearchTime=0, **kwargs):
    """TODO - rewrite this
    minSearchTime - amount of time in seconds to repeat taking
    screenshots and trying to locate a match.  The default of 0 performs
    a single search.
    """
    start = time.time()
    while True:
        try:
            screenshotIm = screenshot(region=None) # the locateAll() function must handle cropping to return accurate coordinates, so don't pass a region he
