由于某种原因,当我尝试从BytesIO蒸汽制作图像时,它无法识别图像.这是我的代码：
from PIL import Image,ImageGrab from io import BytesIO i = ImageGrab.grab() i.resize((1280,720)) output = BytesIO() i.save(output,format = "JPEG") output.flush() print(isinstance(Image.open(output),Image.Image))
并且它抛出的错误的堆栈跟踪：
Traceback (most recent call last):
File "C:/Users/Natecat/PycharmProjects/Python/test.py",line 9,in <module>
print(isinstance(Image.open(output),Image.Image))
File "C:\Python27\lib\site-packages\PIL\Image.py",line 2126,in open
% (filename if filename else fp))
IOError: cannot identify image file <_io.BytesIO object at 0x02394DB0>
我正在使用枕头实施PIL.
