<p> EGL&trade; 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. </p>
<p> 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). </p>
<p> A more detailed overview of EGL functionality and
technical concepts can be found in the <a
target="pagedisplay" href="eglIntro.html">eglIntro</a>
page. </p>

<h2>Browser Compatibility</h2>
<p> The reference pages are now generated in HTML5 format.
Some pages contain imbedded MathML and rely on <a
href="">MathJax</a> 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.
<p> 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. </p>

<h2>Downloading Reference Page Sources</h2>
<p> The Docbook source for the reference pages is available
in the <a
KhronosGroup/EGL-Registry</a> GitHub repository. You can
build a ref page distribution of your own using open
source tools. See the <a
OpenGL refpage README</a> for more information on needed
tools. </p>
<div class="refsect1" id="description">
<p> If you find errors in or problems with the reference
pages, please file a GitHub issue in the <a
KhronosGroup/EGL-Registry</a> GitHub repository. If you
have a fix available, please propose a pull request in
the same repository. </p>
