本文介绍了Python ValueError:从bash管道读取png文件时嵌入了空字节的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
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/python3/dist-packages/PIL/Image.py", line 2258, in open
fp = builtins.open(filename, "rb")
ValueError: embedded null byte
推荐答案
首先尝试将原始数据加载到BytesIO
容器中:
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))
