问题描述

如何在不保存到磁盘然后打开'out.png'的情况下执行此操作?

How do you do this without saving to disk and then opening 'out.png' ?

    r = requests.get(url)
    mine,encoded =  r.json()[0]['data'].split(',') #if it is segmentation
    decoded = base64.decodestring(encoded)

    if mine == 'data:image/png;base64':
        #TODO do this from memory
        g = open("out.png", "w")
        g.write(decoded)
        g.close()            

        r = png.Reader('out.png')
        print r.read()

推荐答案

使用 bytes 关键字

r = png.Reader(bytes=decoded)
