GLGETTEXFILTERFUNCSGIS(3GL)			   GLGETTEXFILTERFUNCSGIS(3GL)

NAME
       glGetTexFilterfuncSGIS - gets texture filter4 function.

C SPECIFICATION
       void glGetTexFilterfuncSGIS( GLenum target,
				    GLenum filter,
				    const GLfloat * weights )

PARAMETERS
       target	The target texture.  Must be GL_TEXTURE_1D or GL_TEXTURE_2D.

       filter	The filter mode.  Must be GL_FILTER4_SGIS.

       weights	Pointer to array of filter weights

DESCRIPTION
       The filter weights for the filter4 filter associated with a texture are
       queried by calling glGetTexFilterFuncSGIS with <target> set to the tex‐
       ture  target and <filter> set to GL_FILTER4_SGIS.  The Size weight val‐
       ues are returned in the array <weights>, which must have at least  Size
       elements.   The value Size is an implementation dependent constant that
       is queried by the application by calling glGetTexParameteriv or	glGet‐
       TexParameterfv.

       This api is part of the SGIS_texture_filter4 extension.	This extension
       allows 1D and 2D textures to be filtered using an  application-defined,
       four sample per dimension filter.  (In addition to the NEAREST and LIN‐
       EAR filters defined in the original GL Specification.)  Such  filtering
       results	in  higher image quality. For more information, please see the
       man page for glTexFilterFuncSGIS.

       The contents of the Filter4 function table is specified using glTexFil‐
       terfuncSGIS. <target> must be either GL_TEXTURE_1D or GL_TEXTURE_2D.

NOTES
       glGetTexFilterFuncSGIS is not included in display lists

ERRORS
       GL_INVALID_ENUM	is generated if glGetTexFilterFuncSGIS parameter <tar‐
       get> is not GL_TEXTURE_1D or GL_TEXTURE_2D.

       GL_INVALID_ENUM is generated if glGetTexFilterFuncSGIS parameter	 <fil‐
       ter> is not GL_FILTER4_SGIS.

       GL_INVALID_OPERATION is generated if glGetTexFilterFuncSGIS is executed
       between execution of glBegin and the corresponding execution of glEnd.

ASSOCIATED CALLS
       glTexfilterfuncSGIS.
