导读：from PIL import Imagefrom subprocess import Popen,PIPEscr = Image.open(Popen.communicate(Popen(['import','-w','0x02a00001','png:-'],stdout=PIPE))[0]) 错误： File "/usr/lib/python3/dist-packages/PIL/Image.py",line 2258,in open fp = builtins

from PIL import Image
from subprocess import Popen,PIPE

scr = Image.open(Popen.communicate(Popen(['import','-w','0x02a00001','png:-'],stdout=PIPE))[0])

错误：

  File "/usr/lib/python3/dist-packages/PIL/Image.py",line 2258,in open
    fp = builtins.open(filename,"rb")
ValueError: embedded null byte

最佳答案

首先尝试将原始数据加载到BytesIO容器中：

from io import BytesIO
from PIL import Image
from subprocess import Popen,PIPE

data = Popen.communicate(Popen(['import',stdout=PIPE))[0]
scr = Image.open(BytesIO(data))
