How to implement jpg format decoder？
I have find a open source TJpgDec http://elm-chan.org/fsw/tjpgd/00index.html, But dont know how to use it on lvgl.

Another question, Does LVGL seem to not support image scaling? Let’s say I scale 800x800 or 800x600 to a fixed 96x96.

What MCU/Processor/Board and compiler are you using?

esp32

What do you want to achieve?

  1. jpg decoder
  2. image scale

Thanks!

LittlevGL does not support scaling images. You will have to create them at the size you want.

As reference here is the integration of a PNG library:
