# FreeType integration with LVGL
**This repository is merged into the lvgl repository. See https://docs.lvgl.io/master/libs/freetype.html**
Interface to FreeType to generate font bitmaps run time
## Install FreeType
- Download Freetype from [here](https://sourceforge.net/projects/freetype/files/)
- `make`
- `sudo make install`
## Add FreeType to your project
- Add include path: `/usr/include/freetype2` (for GCC: `-I/usr/include/freetype2 -L/usr/local/lib`)
- Add library: `freetype` (for GCC: `-L/usr/local/lib -lfreetype`)
## Usage in LVGL
To enable cache, set`LV_USE_FT_CACHE_MANAGER 1`in lv_freetype.h.
```c
/*Init freetype library
*Cache max 64 faces and 1 size*/
lv_freetype_init(64, 1, 0);
/*Create a font*/
static lv_ft_info_t info;
info.name = "./lv_lib_freetype/arial.ttf";
info.weight = 16;
info.style = FT_FONT_STYLE_NORMAL;
lv_ft_font_init(&info);
/*Create style with the new font*/
static lv_style_t style;
lv_style_init(&style);
lv_style_set_text_font(&style, info.font);
/*Create a label with the new style*/
lv_obj_t * label = lv_label_create(lv_scr_act());
lv_obj_add_style(label, &style, 0);
lv_label_set_text(label, "Hello world");
```
