• # Introduction
  
  This page details the extensions that are supported by ANGLE.
  
  Specifications for GLES extensions can be found in the [Khronos OpenGL ES API
  Registry](http://www.khronos.org/registry/gles/)
  
  Specifications for EGL extensions can be found in the [Khronos EGL API Registry]
  (http://www.khronos.org/registry/egl/)
  
  Specifications for ANGLE-specific extensions can be found in the [ANGLE
  extension registry]
  (https://code.google.com/p/angleproject/source/browse/?name=master#git%2Fextensions)
  
  # Details
  
  ## GLES extensions
  
  *   GL\_OES\_element\_index\_uint (fn1)
  *   GL\_OES\_get\_program\_binary
  *   GL\_OES\_packed\_depth\_stencil
  *   GL\_OES\_rgb8\_rgba8
  *   GL\_OES\_standard\_derivatives
  *   GL\_OES\_texture\_half\_float (fn1)
  *   GL\_OES\_texture\_half\_float\_linear (fn1)
  *   GL\_OES\_texture\_float (fn1)
  *   GL\_OES\_texture\_float\_linear (fn1)
  *   GL\_OES\_texture\_npot (fn1)
  *   GL\_EXT\_occlusion\_query\_boolean (fn1)
  *   GL\_EXT\_read\_format\_bgra
  *   GL\_EXT\_robustness
      *   reset notifications and sized queries only, no robust buffer access
  *   GL\_EXT\_texture\_compression\_dxt1 (fn1)
  *   GL\_EXT\_texture\_filter\_anisotropic (fn1)
  *   GL\_EXT\_texture\_format\_BGRA8888
  *   GL\_EXT\_texture\_storage
  *   GL\_ANGLE\_depth\_texture
      *   requires support for INTZ and NULL surfaces in D3D9 (see
          http://aras-p.info/texts/D3D9GPUHacks.html)
  *   GL\_ANGLE\_framebuffer\_blit
  *   GL\_ANGLE\_framebuffer\_multisample (fn1)
  *   GL\_ANGLE\_instanced\_arrays
      *   requires SM3 support
  *   GL\_ANGLE\_pack\_reverse\_row\_order
  *   GL\_ANGLE\_texture\_compression\_dxt3 (fn1)
  *   GL\_ANGLE\_texture\_compression\_dxt5 (fn1)
  *   GL\_ANGLE\_texture\_usage
  *   GL\_ANGLE\_translated\_shader\_source
  *   GL\_NV\_fence (fn1)
  
  ## EGL Extensions
  
  *   EGL\_EXT\_create\_context\_robustness
      *   only reset notifications supported
  *   EGL\_ANGLE\_d3d\_share\_handle\_client\_buffer (fn2)
  *   EGL\_ANGLE\_query\_surface\_pointer
  *   EGL\_ANGLE\_software\_display (fn3)
  *   EGL\_ANGLE\_surface\_d3d\_texture\_2d\_share\_handle (fn2)
  *   EGL\_NV\_post\_sub\_buffer
  
  ### Notes
  
  *   fn1: extensions are only exposed if underlying D3D9 device has support for
      the required features
  *   fn2: extensions are only exposed when running on D3D9Ex (ie Win Vista/7)
  *   fn3: extension is only exposed when swiftshader is present
