Question

我正在写一个关于tkinter的程序，类似于photoshop（图像处理），问题是我的一个函数（Moyenne（））告诉我索引超出范围，但它之前有效，但现在没有。我搜索过但我还没找到任何东西。如果您需要任何规格，请询问;）

from PIL import Image

rouge=0
vert=0
bleu=0
for x in range(1,z[0]-1):
    for y in range(1,z[1]-1):
        for t in range(-1,1):
            print(t)
            for w in range(-1,1):
                print(w)
                k=px[x+t,y+w]
                if k[0]>k[1] and k[0]>k[2]:
                    rouge=rouge+1
                if k[1]>k[0] and k[1]>k[2]:
                    vert=vert+1
                if k[2]>k[1] and k[2]>k[0]:
                    bleu=bleu+1
        x=x-1
        y=y-1
        Max=rouge
        if bleu>Max:
            Max=bleu
        elif vert>Max:
            Max=vert
        pax=px[x,y]
        if Max == rouge:
            pax=(pax[0],0,0)
        if Max == vert:

Answer 1

您的问题是由Moyenne()

正文中的这些陈述引起的

x=x-1
y=y-1

无论出于何种原因，您都会在循环体中手动递减循环变量。这最终会导致x在到达k=px[x+t,y+w]时变为0，如果t为-1，则会导致您尝试访问索引{{}处的像素1}}，导致＆＃34;索引超出范围＆＃34;你看错了。

PIL图像索引超出范围
