Python ValueError：从bash管道读取png文件时嵌入的空字节

概述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/pytho

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.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 BytesIOfrom PIL import Imagefrom subprocess import Popen,PIPEdata = Popen.communicate(Popen(['import',stdout=PIPE))[0]scr = Image.open(BytesIO(data))
