fglColorTableParameterSGI(3G)  OpenGL Reference	 fglColorTableParameterSGI(3G)

NAME
     fglColorTableParameterfvSGI, fglColorTableParameterivSGI - set color
     lookup table parameters

FORTRAN SPECIFICATION
     SUBROUTINE fglColorTableParameterfvSGI( INTEGER*4 target,
					     INTEGER*4 pname,
					     CHARACTER*8 params )
     SUBROUTINE fglColorTableParameterivSGI( INTEGER*4 target,
					     INTEGER*4 pname,
					     CHARACTER*8 params )

PARAMETERS
     target  The target color table.  Must be GL_COLOR_TABLE_SGI,
	     GL_POST_CONVOLUTION_COLOR_TABLE_SGI,
	     GL_POST_COLOR_MATRIX_COLOR_TABLE_SGI, or
	     GL_TEXTURE_COLOR_TABLE_SGI.

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

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

DESCRIPTION
     fglColorTableParameterSGI is part of the SGI_color_table extension, which
     adds several color lookup tables to the pixel transfer path.

     fglColorTableParameterSGI 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_SGI,
     GL_POST_CONVOLUTION_COLOR_TABLE_SGI,
     GL_POST_COLOR_MATRIX_COLOR_TABLE_SGI, or GL_TEXTURE_COLOR_TABLE_SGI.

     pname must be GL_COLOR_TABLE_SCALE_SGI 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_SGI 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 fglColorTableSGI.

NOTES
     fglColorTableParameterSGI is part of the SGI_color_table extension.
     GL_TEXTURE_COLOR_TABLE_SGI is part of the SGI_texture_color_table
     extension.	 See fglIntro for more information on using extensions.

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

     GL_INVALID_OPERATION is generated if fglColorTableParameterSGI is
     executed between the execution of fglBegin and the corresponding
     execution of fglEnd.

ASSOCIATED GETS
     fglGetColorTableParameterSGI

MACHINE DEPENDENCIES
     The SGI_color_table extension is not supported on RealityEngine,
     RealityEngine2, and VTX systems.
