# FreeType support
|
||
|
|
Interface to [FreeType](https://www.freetype.org/) 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
|
||
|
|
|
||
|
|
Enable `LV_USE_FREETYPE` in `lv_conf.h`.
|
||
|
|
|
||
|
|
See the examples below.
|
||
|
|
|
||
|
|
Note that, the FreeType extension doesn't use LVGL's file system.
|
||
|
|
You can simply pass the path to the font as usual on your operating system or platform.
