python - 如何使用 pyautogui 处理图像

问题描述

我想知道是否可以pyautogui.locateOnScreen()为一个完整的文件夹做这就是我的意思是一个包含 20 个不同图像并在屏幕上找到它们的文件夹。有可能pyautogui吗？否则你会怎么做？

到目前为止，这是我的代码：

from pyautogui import locateAllOnScreen as find
import os
import numpy as np




def try_to_find(x):
    x = os.path.isfile(x)
    if x == None:
        Warning('No images were enterd')   
        
    else:
        folder = x
        value = find(folder)
        
        if value is not None:
            print(f"{x} was found!")
            
        else:
            if value is None:
                print(f"{x} was not found!")
                
        return(list(value))



myfolder = ("ImageQuery")
found = 0

with os.scandir(myfolder) as entries:
    for entry in entries:
        if entry.is_file():
            found+=1
            print(f'Items {found}: {entry.name}')
            try_to_find(entry.name)

如果我运行此代码，我会收到此错误TypeError: expected an image filename, OpenCV numpy array, or PIL image

解决方案

试试这个：

import os
import pyautogui as py


image_list = []

# Get list of all files in current directory
directory = os.listdir()

# Find files that end with .png or .jpg and add to image_list
for file in directory:
    if file.endswith('.png') or file.endswith('.jpg'):
        image_list.append(file)

# Loop through list to find all the images
for image in image_list:
    print(image)
    print(py.locateOnScreen(image))

这个问题与另一个问题相似，我在两个地方都发布了相同的答案。
