gfx VS TJpg_Decoder

This should work with LVGL but I haven't tried it. It does work with https://honeythecodewitch.com/uix and https://honeythecodewitch.com/gfx and the example project uses that.

The graphics library https://honeythecodewitch.com/gfx/

I've developed a graphics library that supports TrueType, SVG, PNG, JPG, alpha blending and X11 colors here: https://honeythecodewitch.com/gfx/

The ESP32 will reboot with a brownout message if you draw too much current. Obviously you want to avoid this, but after writing a graphics library htcw_gfx and writing a ton of drivers for many different displays, I've never had any issues running the backlight off the ESP32's 3.3v pin when plugged into USB, or even on LiPO.

Thx, interesting. Made me G**gle it: https://github.com/codewitch-honey-crisis/gfx

Try out https://github.com/codewitch-honey-crisis/gfx - it works very well on monochrome displays and is lighter than LVGL.

Yes but the point was that you don't have to use a seperate tool to embed images, you can use standard jpgs and use functionality already included with esp-idf. It supports all the esp32-family and this is the esp32 subreddit so I suspect that's good enough for most here. Mika even used it to play video with mjpeg from a sd-card. Embedding files as headers quickly fills up the program flash so it's nice to be able to use expandable storage. And TJpgDec is platform independent as you probably know since you say you included it in your library. It's available for arduino as well.
