# EGL

EGL is an interface between Khronos rendering APIs (such as OpenGL ES and OpenVG) and the underlying native window system. OpenHarmony supports EGL.

## Introducing EGL

To use EGL capabilities, include the following header file:

```cpp
#include <EGL/egl.h>
```

Add the following dynamic link library to **CMakeLists.txt**:

```
libEGL.so
```

To call the EGL extended APIs, include the following header file and add the macro definition to **CMakeLists.txt**:
```
#include <EGL/eglext.h>
EGL_EGLEXT_PROTOTYPES
```

## Supported APIs

Currently, OpenHarmony supports the EGL APIs listed in the topic below. The supported APIs will be continuously updated as the version evolves.
