Hi i have a similar challenge where i need to store the thumbnailPhoto
attribute to my local db and display the image every-time user logs in. But
this solution does work .
data looks like this:
\xff\xd8\xff\xe0\x00\x10JFIF\x00\x01\x01\x01\x00`\x00`\x00\x00\xff\xdb\x00C\x00
\x08\x06\x06\x07\x06\x05\x08\x07\x07\x07\t\t\x08\n\x0c\x14\r\x0c\x0b\x0b\x0c\x19\x12\x13\x0f\x14\x1d\x1a\x1f\x1e\x1d\x1a\x1c\x1c
$.\'
",#\x1c\x1c(7),01444\x1f\'9=82<.342\xff\xdb\x00C\x01\t\t\t\x0c\x0b\x0c\x18\r\r\x182!\x1c!222222222222222222222222222222222
import PIL
from PIL import Image
import io
data = open("bytes.txt")
my_data=(data.read())
photo_inline = io.StringIO(my_data)
photo = PIL.Image.open(photo_inline)
error:
Traceback (most recent call last):
File "convertToImage.py", line 9, in <module>
photo = PIL.Image.open(photo_inline)
File "", line 2657, in open
% (filename if filename else fp))
