# BeeOS Phase 7 Notes

## Completed in this phase

Phase 7 adds the first BeeOS asset conversion pipeline.

New files:

```text
tools/convert_icons_for_lvgl.py
beeos/core/asset_build.py
beeos/generated/icons/icon_build_index.json
beeos/generated/icons/bitmap_json/
beeos/generated/icons/lvgl/
beeos/generated/icons/previews/
```

## Why this matters

The desktop simulator can use PNG icons, but the PineTime Pro firmware/LVGL port will need compact generated assets.

Phase 7 creates an intermediate format:

- compact JSON bitmap rows
- packed 1-bit byte buffers
- C header/source files
- preview sheets

## Not final LVGL descriptors yet

The generated C files are firmware-friendly icon buffers, not full `lv_image_dsc_t` declarations yet.

A future phase can wrap these buffers in LVGL-specific image descriptors once the exact LVGL version and color format are chosen.

## Next possible phase

Phase 8 should probably add:

- actual LVGL image descriptor export option
- theme export tool
- watch face package runtime
- HiveStore update simulation
- app settings pages
