图片操作

从string.io导入

import sys
import PIL
from cStringIO import StringIO
from reportlab.platypus.flowables import Image
# Method 1
data = open(sys.argv[1]).read()
img1 = StringIO(data)
# Method 2
img2 = StringIO()
PIL.Image.open(sys.argv[2]).save(img2, 'PNG')
img2.seek(0)
# Method 3 (fails)
img3 = StringIO(PIL.Image.open(sys.argv[2]).tostring())
story = [Image(img1), Image(img2)]
#Image(img3)
