NAME

       glColorTableParameterfv, glColorTableParameteriv - set color lookup table parameters

C SPECIFICATION

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