解决方法:
到http://www.lfd.uci.edu/~gohlke/pythonlibs/下载pillow,安装
然后创建如下代码测试
1: import os,sys
2: from PIL import Image
3:
4: pic = Image.open("test.png")
5: pic.show()
pip是一个很好的工具,类似apt,可以为python管理模块

缩小图片操作
1: import os,sys
2: from PIL import Image
3:
4:
5: MAX_WIDTH = 2048
6: MAX_HEIGHT = 1536
7:
8:
9: pic = Image.open("test1.jpg")
10: width,height = pic.size
11:
12:
13: small = pic.resize((width / 2,height / 2))
14: ##small.show()
15: small.save("test1_small.jpg")
