NAME
       glColorTableParameteriv,	 glColorTableParameterfv  -  set color lookup
       table parameters


C SPECIFICATION
       void glColorTableParameteriv( GLenum target,
				     GLenum pname,
				     const GLint *params )
       void glColorTableParameterfv( GLenum target,
				     GLenum pname,
				     const GLfloat *params )


PARAMETERS
       target  The   target   color   table.	Must	be    GL_COLOR_TABLE,
	       GL_POST_CONVOLUTION_COLOR_TABLE,				   or
	       GL_POST_COLOR_MATRIX_COLOR_TABLE.

       pname   The symbolic name of a texture color lookup  table  parameter.
	       Must be one of GL_COLOR_TABLE_SCALE or GL_COLOR_TABLE_BIAS.

       params  A  pointer  to an array where the values of the parameters are
	       stored.

DESCRIPTION
       glColorTableParameter is used to specify the scale  factors  and	 bias
       terms  applied  to  color components when they are loaded into a color
       table. target indicates which color table the  scale  and  bias	terms
       apply	 to;	 it	must	 be	set	to    GL_COLOR_TABLE,
       GL_POST_CONVOLUTION_COLOR_TABLE, or  GL_POST_COLOR_MATRIX_COLOR_TABLE.

       pname  must be GL_COLOR_TABLE_SCALE to set the scale factors.  In this
       case, params points to an array of four values, which  are  the	scale
       factors for red, green, blue, and alpha, in that order.

       pname must be GL_COLOR_TABLE_BIAS to set the bias terms. In this case,
       params points to an array of four values, which are the bias terms for
       red, green, blue, and alpha, in that order.

       The color tables themselves are specified by calling glColorTable.

NOTES
       glColorTableParameter  is available only if GL_ARB_imaging is returned
       from calling glGetString with an argument of GL_EXTENSIONS.

ERRORS
       GL_INVALID_ENUM is generated if target or pname is not  an  acceptable
       value.

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