EGL Reference Pages

EGL™ is an interface between Khronos rendering APIs such as OpenGL ES or OpenVG and the underlying native platform window system. It handles graphics context management, surface/buffer binding, and rendering synchronization and enables high-performance, accelerated, mixed-mode 2D and 3D rendering using other Khronos APIs.

The reference pages describe EGL 1.5, but can be used with earlier versions since each page notes when features are available only starting with specific older versions (1.2, 1.3, and 1.4).

A more detailed overview of EGL functionality and technical concepts can be found in the eglIntro page.

Browser Compatibility

The reference pages are now generated in HTML5 format. Some pages contain imbedded MathML and rely on MathJax to render mathematical equations on browsers which do not natively support MathML. This should work much better on Chrome, Safari, and other browsers which don't support MathML.

However, HTML5 isn't well supported on IE 8 or earlier versions. We recommend you use a more recent browser for viewing the reference pages.

Downloading Reference Page Sources

The Docbook source for the reference pages is available in the KhronosGroup/EGL-Registry GitHub repository. You can build a ref page distribution of your own using open source tools. See the OpenGL refpage README for more information on needed tools.

Feedback

If you find errors in or problems with the reference pages, please file a GitHub issue in the KhronosGroup/EGL-Registry GitHub repository. If you have a fix available, please propose a pull request in the same repository.
