"""Generate LVGL colour icon descriptors from Twemoji PNGs.
|
|
|
|
Downloads the Twemoji 72x72 PNGs for the glyphs the Lisael Box UI needs,
|
|
downscales them (Pillow/Lanczos) and converts each to an LVGL RGB565A8
|
|
`lv_image_dsc_t` C source in ``main/ui/assets/``.
|
|
|
|
Run with a Python that has both Pillow and pypng available, e.g. the
|
|
ESP-IDF venv:

~/.espressif/python_env/idf5.4_py3.14_env/bin/python tools/gen_icons.py
