注意:这是一个自我回答的问题.

我正在尝试使用Python代码调整图像大小,但我收到以下奇怪的错误:

Traceback (most recent call last):
  File "resize.py", line 5, in <module>
    logo.save("StartMyProjects_resized.png", format="PNG")
  File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 1439, in save
    save_handler(self, fp, filename)
  File "/usr/lib/python2.7/dist-packages/PIL/PngImagePlugin.py", line 572, in _save
    ImageFile._save(im, _idat(fp, chunk), [("zip", (0,0)+im.size, 0, rawmode)])
  File "/usr/lib/python2.7/dist-packages/PIL/ImageFile.py", line 481, in _save
    e = Image._getencoder(im.mode, e, a, im.encoderconfig)
  File "/usr/lib/python2.7/dist-packages/PIL/Image.py", line 399, in _getencoder
    return apply(encoder, (mode,) + args + extra)
TypeError: an integer is required

我正在使用的代码是:

import Image

logo = Image.open("my_image.png")
logo = logo.resize((100, 100), Image.ANTIALIAS)
logo.save("my_image_resized.png")
