包含“属性错误”的函数有什么问题

Question

嘿，我的代码有这个错误，但我不知道为什么

这个函数的代码是：

def rotateImage90(image):
    ei = EmptyImage(image.getHeight(), image.getWidth())
    for i in range (image.getWidth()):
        for j in range(image.getHeight()):
            orginal = image.getPixel(i, j)
            ei.setPixel(image.getHeight() - j - 1, i, orginal)
    return ei

我得到的错误是

Traceback (most recent call last):
File "<pyshell#24>", line 1, in <module>
  drawImage("Spiderman", [spiderman, rotateImage90(spiderman)]) 
File "/Users/luisarroyo/Documents/project 7.py", line 52, in rotateImage90
  orginal = image.getPixel(i, j)
