Question

我有一个类似于Photoshop的图像处理程序，但非常简单（按钮和图像显示）。在我的程序中，您可以选择要使用和修改的图像。我目前正在研究程序的popart部分，但是当我使用CheGevara的图像（称为“chev.png”）时，它会出现以下错误（函数是“def PopArt（）”）：

Exception in Tkinter callback
Traceback (most recent call last):
  File "C:\EduPython\App\lib\tkinter\__init__.py", line 1538, in __call__
    return self.func(*args)
  File "C:\Users\omar\Desktop\azer\Test 1.py", line 52, in PopArt
    o=int((p[0]+p[1]+p[2])/3)
TypeError: 'int' object is not subscriptable

当我使用其他图像如“fleur1.png”或“face.png”时，它工作正常并显示修改就好了。这是代码：

以下是我使用的图片（所有图片都是png，但是chev.png和fleur.png是从jpg转换而来的，而fleur1.png是从fleur.png调整大小的）：

chev.png

编辑：其他图片在评论中，因为我不能在帖子中添加超过1个链接

Answer 1

事实上我找到了解决方案。我的chev.png是一个灰度图像，所以他的像素值是一个整数，其他的是元组（R，G，B）。所以我所要做的就是检查像素的类型：

if type(p)==int:

然后如果它是一个整数，他将它转换为元组：

p=(p,p,p)
