PIL open() method not working with BytesIO

Question

For some reason, when I try to make an image from a BytesIO steam, it can\'t identify the image. Here is my code:

from PIL import Image, ImageGrab
from io im         


        

Answer 1

Think of BytesIO as a file object, after you finish writing the image, the file's cursor is at the end of the file, so when Image.open() tries to call output.read(), it immediately gets an EOF.

You need to add a output.seek(0) before passing output to Image.open().
