ESP-Brookesia LVGL backend and image packaging helpers for GUI documents.
Readme
# ESP-Brookesia GUI LVGL Backend * [中文版本](./README_CN.md) ## Overview `brookesia_gui_lvgl` is the LVGL backend and image packaging helper set for GUI Interface documents. For more information, see the [ESP-Brookesia Programming Guide](https://docs.espressif.com/projects/esp-brookesia/en/latest/gui/lvgl/index.html). ## How to Use ### Runtime Image Formats The LVGL backend supports LVGL ``.bin``, PNG, and JPEG files referenced by JSON UI ``imageSet`` assets. JPEG resources use ``.jpg`` or ``.jpeg`` extensions, are validated and preloaded into a reference-counted cache, and can provide their dimensions from the JPEG frame header. On ESP, enable ``CONFIG_ESP_LVGL_ADAPTER_ENABLE_DECODER``. On PC and WASM, enable ``LV_USE_TJPGD`` and ``LV_USE_FS_MEMFS`` in the LVGL configuration. Loading a JPEG returns an explicit path-based error when the decoder is unavailable or the file is invalid. ### Environment Requirements Please refer to the following documentation: - [ESP-Brookesia Programming Guide - Versioning](https://docs.espressif.com/projects/esp-brookesia/en/latest/getting_started.html#getting-started-versioning) - [ESP-Brookesia Programming Guide - Development Environment Setup](https://docs.espressif.com/projects/esp-brookesia/en/latest/getting_started.html#getting-started-dev-environment) ### Add to Your Project Please refer to [ESP-Brookesia Programming Guide - How to Obtain and Use Components](https://docs.espressif.com/projects/esp-brookesia/en/latest/getting_started.html#getting-started-component-usage).
