NAME
       glGetColorTableParameterfv, glGetColorTableParameteriv - get color
       lookup table parameters

C SPECIFICATION
       void glGetColorTableParameterfv( GLenum target,
	    GLenum pname,
	    GLfloat *params )
       void glGetColorTableParameteriv( GLenum target,
	    GLenum pname,
	    GLint *params )

       delim $$

PARAMETERS
       target The target color table.  Must be GL_COLOR_TABLE,
	      GL_POST_CONVOLUTION_COLOR_TABLE,
	      GL_POST_COLOR_MATRIX_COLOR_TABLE, GL_PROXY_COLOR_TABLE,
	      GL_PROXY_POST_CONVOLUTION_COLOR_TABLE,
	      GL_PROXY_POST_COLOR_MATRIX_COLOR_TABLE.

       pname  The symbolic name of a color lookup table parameter.  Must be
	      one of GL_COLOR_TABLE_BIAS, GL_COLOR_TABLE_SCALE,
	      GL_COLOR_TABLE_FORMAT, GL_COLOR_TABLE_WIDTH,
	      GL_COLOR_TABLE_RED_SIZE, GL_COLOR_TABLE_GREEN_SIZE,
	      GL_COLOR_TABLE_BLUE_SIZE, GL_COLOR_TABLE_ALPHA_SIZE,
	      GL_COLOR_TABLE_LUMINANCE_SIZE, or GL_COLOR_TABLE_INTENSITY_SIZE.

       params A pointer to an array where the values of the parameter will be
	      stored.

DESCRIPTION
       Returns parameters specific to color table target.

       When pname is set to GL_COLOR_TABLE_SCALE or GL_COLOR_TABLE_BIAS,
       glGetColorTableParameter returns the color table scale or bias
       parameters for the table specified by target.  For these queries,
       target must be set to GL_COLOR_TABLE, GL_POST_CONVOLUTION_COLOR_TABLE,
       or GL_POST_COLOR_MATRIX_COLOR_TABLE and params points to an array of
       four elements, which receive the scale or bias factors for red, green,
       blue, and alpha, in that order.

       glGetColorTableParameter can also be used to retrieve the  and size
       parameters for a color table. For these queries, set target to either
       the color table target or the proxy color table target.	The  and size
       parameters are set by glColorTable.

       The following table lists the  and size parameters that may be queried.
       For each symbolic constant listed below for pname, params must point to
       an array of the given length, and receive the values indicated.

       -------------------------------------------------------------------
       Parameter		       N   Meaning
       -------------------------------------------------------------------
       GL_COLOR_TABLE_FORMAT	       1   Internal  (e.g. GL_RGBA)
       GL_COLOR_TABLE_WIDTH	       1   Number of elements in table
       GL_COLOR_TABLE_RED_SIZE	       1   Size of red component, in bits
       GL_COLOR_TABLE_GREEN_SIZE       1   Size of green component
       GL_COLOR_TABLE_BLUE_SIZE	       1   Size of blue component
       GL_COLOR_TABLE_ALPHA_SIZE       1   Size of alpha component
       GL_COLOR_TABLE_LUMINANCE_SIZE   1   Size of luminance component
       GL_COLOR_TABLE_INTENSITY_SIZE   1   Size of intensity component
       -------------------------------------------------------------------

NOTES
       glGetColorTableParameter is present only if GL_ARB_imaging is returned
       when glGetString is called 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 glGetColorTableParameter is
       executed between the execution of glBegin and the corresponding
       execution of glEnd.
