LVGL 9, Online image converter, Indexed (2bit) not available, why?

How-to
1

Hello,

In LVGL 9, it seems no longer possible to convert images to indexed 2-bit or similar formats using the online image converter.
Why is that?
Is this format no longer supported in LVGL 9?

If it’s no longer supported, I’m having trouble understanding the reasoning behind this decision, as indexed formats can significantly save memory, especially for applications on small microcontrollers.

Am I missing something?

Thank you

The online converter is a little limited, but a full featured converted can be used here.

Ok thank you.
And how does the command look to convert a PNG image to an Indexed 2-Bit format, similar as the Online Converter does, but specifically for LVGL 9?
Should this be understood directly from the Python program, or is there a guide available?

E.g.:
python lvgl/scripts/LVGLImage.py --?? --cf ?? --?? … --?? -o ?? picture.png

It should be something like:

python3 LVGLImage.py --ofmt C --cf I2 picture.png
