Python ValueError: embedded null byte when reading png file from bash pipe

Question

from PIL import Image
from subprocess import Popen, PIPE

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


        

Answer 1

Try first to load raw data into a BytesIO container:

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

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