"""把 assets/ 里的 UI 素材转成 LVGL v9 二进制图片（.bin），供表盘运行时加载。
|
||
|
|
|
||
|
|
尺寸取自 tools/pages.py 的 480 档规格：列表图标 31x31、返回箭头 18x29、关于页 logo 80x80。
|
||
|
|
格式（已在真机验证）:
|
||
|
|
header 12B: magic=0x19 | cf | flags | w | h | stride | reserved
|
||
|
|
cf=0x10 ARGB8888 -> 数据为 BGRA，长度 = w*h*4
|
||
|
|
编码器用 iconpack.encode（与图标包同一套，字节级验证过）。
