NAME
       glColorTableParameteriv, glColorTableParameterfv - set color lookup ta‐
       ble 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 ta‐
       ble. 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.

       glGetColorTableParameter
