GLCOLORTABLEPARAMETE(3G)	 OpenGL Manual	      GLCOLORTABLEPARAMETE(3G)

NAME
       glColorTableParameter - 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
       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 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()
