I think there is an advanced function:

Help on built-in function icon in module pyxel.pyxel_wrapper:
icon(data, scale, colkey=None)

from pyxel.

I see, but the problem is I don't know how to use this function. Do you have any ideas?

As mentioned in the README, you can check all of the Pyxel APIs here:

Advanced APIs

Pyxel has "advanced APIs" that are not mentioned in this reference because they "may confuse users" or "need specialized knowledge to use".

If you are familiar with your skills, try to create amazing works with this as a clue!

And the API is

def icon(data: List[str], scale: int, colkey: Optional[int]) -> None: ...

The format for data is the same as the Image.set method which is used in the example 03.
