How to return a list of extracted images as file objects?

[kramer65]

I'm trying to use pdfminer to extract qr-codes from a pdf. I can currently use pdfminer to extract all images, see which ones contain QR-codes, and then delete those images again. To save this step of image creation and subsequent deletion, I'm trying to get pdfminer to return a list of images as file objects so that I can use QRTools (https://launchpad.net/qr-tools) without the need to store the images.

Is there a way that I can do this with pdfminer? All tips are welcome!
