Overview

This extension exposes the EXT_texture_filter_anisotropic functionality to WebGL.

There are no WebGL-specific behavioral changes.

Consult the above extension for documentation, issues and new functions and enumerants.

When this extension is enabled:

• The getTexParameter, texParameterf and texParameteri entry points' parameter pname accepts the value TEXTURE_MAX_ANISOTROPY_EXT
• The getParameter entry point parameter pname accepts the value MAX_TEXTURE_MAX_ANISOTROPY_EXT, returning a value of type float.

IDL

[Exposed=(Window,Worker), LegacyNoInterfaceObject]

  const GLenum TEXTURE_MAX_ANISOTROPY_EXT       = 0x84FE;
  const GLenum MAX_TEXTURE_MAX_ANISOTROPY_EXT   = 0x84FF;
};
