打开页面源码发现一句提示：let me get this straight，提示说把它弄直，图片里面杂乱无章的点很明显有很多是品红色的短线，把图按行平移，使得红线对齐。

源代码为： 

import Image, ImageChops    
image = Image.open("mozart.gif")  
magic = chr(195)  
for y in range(image.size[1]):  
     box = 0, y, image.size[0], y + 1  
     row = image.crop(box)  
     bytes = row.tostring()  
     i = bytes.index(magic)  
     row = ImageChops.offset(row, -i)  
     image.paste(row, box)  
image.save("new.gif")
