Portenta Camera to JPEG or BMP to SD card

Hardware Portenta Portenta Vision Shield
1

So I can save data to the Portenta SD card using the default example and can do a bunch of utilities on data using the SD card here . I can read the vision shield camera frame_buffer here putting it on a grayscale OLED even after the deprecating changes of Arduino MBED version 2.8.0.

Wondering if anyone has taken that Grayscale 320x320 data and saved it to the SD card in a recognizable format such as BMP, PNG or JPG?

@pert ?

Just found these which might help PNG decoder and encoder libraries.

@JerTeach Looks like this just posted. I tried it and it worked perfectly for BMPs on a Portenta H7 with Vision Shield with a 32G SD card.
