[ JPG DECODER] Do we have ready for support decoder JPG format?


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?


What do you want to achieve?

  1. jpg decoder
  2. image scale


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

Hi, what about JPG decoder feature?

LittlevGL doesn’t have built-in JPG decoding but it has an image decoder interface to attach external libraries. Take a look at this part of documentation: https://docs.littlevgl.com/en/html/overview/image.html#image-decoder

As reference here is the integration of a PNG library:
