You mean how nanodlp display images? Windows / Linux ports are using GLFW/OpenGL. Raspberry version directly calling gpu firmware blob.

For raspberry version.
There are the beginnings of raspberry and python.
Please example or a link to documentation.
I found only "fbi" and "fim".

Re: Display png

Those tools are framebuffer based, performance is acceptable and very easy to implement but I had experienced some glitch using framebuffer solution on RPi. If you could make it works, it will work with any linux box.

There is no straight forward example as I remember. You should dig raspberry pi firmware repo. https://github.com/raspberrypi/firmware/
If you want to use python you probably will have to use python c binding.
