How to pass/read a PIL.JpegImagePlugin.JpegImageFile object?

Question

I have a PDF file that I convert to jpeg. What I get is a list of images:

[<PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=1700x2200 at 0x7F0FF46CDC10>,
 <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=1700x2200 at 0x7F0FE6651750>,
 <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=1700x2200 at 0x7F0FE6657450>,
 <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=1700x2200 at 0x7F0FE6657550>,
 <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=1700x2200 at 0x7F0FE6657650>,
 <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=1700x2200 at 0x7F0FE6657790>]

I need to pass each of them to my AWS Textract pipeline to extract the tables and text.

The issue I can't pass these objects, they aren't files which I can open. Please advise how to read/load such objects?

I believe you want a JPEG-encoded image in a memory buffer:

import io
from PIL import Image

# Encode your PIL Image as a JPEG without writing to disk
buffer = io.BytesIO()
YourImage.save(buffer, format='JPEG', quality=75)

# You probably want
desiredObject = buffer.getbuffer()
