How to pipe image into fbv?

[sunknudsen]

This project looks amazing!

I am looking for a way to display QR codes on Raspberry Pis without requiring a desktop environment.

The QR codes are generated in memory... I would like to display them to the framebuffer without having to write them to disk.

Is it possible to pipe images to fbv?

Currently, we don't support show image in memory.
You can store it in /tmp before displaying.

That's a useful feature we may add in the future.

Thanks for the follow-up @godspeed1989.

You can store it in /tmp before displaying.

For security reasons, I am trying to avoid writing to disk in case /tmp is not a memory disk.

How much work do you believe is required to allow piping an image to stdin?
