Python PIL int對象不可下標

Question

我有一個圖像處理程序，類似於Photoshop，但非常簡單（按鈕和圖像顯示）。在我的程序中，您可以選擇想要使用和修改的圖像。我目前正在研究程序的popart部分，但是當我使用CheGevara的圖像（稱爲「chev.png」）時，它會給出以下錯誤（函數是「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 

當我使用像「fleur1.png」或「face.png」等其他圖像時，它工作正常，並顯示修改就好。下面的代碼：

下面是我使用的圖像（所有的人都PNG，但chev.png和fleur.png從JPG轉換，並fleur1.png從fleur.png調整）：

chev.png

編輯：其他的圖片都在評論，因爲我不能把超過1個鏈接在我的崗位

Answer 1

事實上，我找到了解決辦法。 My chev.png是灰度級圖像，所以他的像素值是一個整數，其他元素是元組（R，G，B）。因此，所有我要做的就是檢查像素的類型：

if type(p)==int: 

那麼，如果它是一個整數，他把它轉換成一個元組：

p=(p,p,p) 

和你所有的設置;）
