fglColorSubTable(3G)	       OpenGL Reference		  fglColorSubTable(3G)

NAME
     fglColorSubTable - respecify a portion of a color table

FORTRAN SPECIFICATION
     SUBROUTINE fglColorSubTable( INTEGER*4 target,
				  INTEGER*4 start,
				  INTEGER*4 count,
				  INTEGER*4 format,
				  INTEGER*4 type,
				  CHARACTER*8 data )

PARAMETERS
     target  Must be one of GL_COLOR_TABLE, GL_POST_CONVOLUTION_COLOR_TABLE,
	     or GL_POST_COLOR_MATRIX_COLOR_TABLE.

     start   The starting index of the portion of the color table to be
	     replaced.

     count   The number of table entries to replace.

     format  The format of the pixel data in data.  The allowable values are
	     GL_RED, GL_GREEN, GL_BLUE, GL_ALPHA, GL_LUMINANCE,
	     GL_LUMINANCE_ALPHA, GL_RGB, GL_BGR, GL_RGBA, GL_BGRA, and
	     GL_ABGR_EXT.

     type    The type of the pixel data in data.  The allowable values are
	     GL_UNSIGNED_BYTE, GL_BYTE, GL_UNSIGNED_SHORT, GL_SHORT,
	     GL_UNSIGNED_INT, GL_INT, GL_FLOAT, GL_UNSIGNED_BYTE_3_3_2,
	     GL_UNSIGNED_BYTE_2_3_3_REV, GL_UNSIGNED_SHORT_5_6_5,
	     GL_UNSIGNED_SHORT_5_6_5_REV, GL_UNSIGNED_SHORT_4_4_4_4,
	     GL_UNSIGNED_SHORT_4_4_4_4_REV, GL_UNSIGNED_SHORT_5_5_5_1,
	     GL_UNSIGNED_SHORT_1_5_5_5_REV, GL_UNSIGNED_INT_8_8_8_8,
	     GL_UNSIGNED_INT_8_8_8_8_REV, GL_UNSIGNED_INT_10_10_10_2, and
	     GL_UNSIGNED_INT_2_10_10_10_REV.

     data    Pointer to a one-dimensional array of pixel data that is
	     processed to replace the specified region of the color table.

DESCRIPTION
     fglColorSubTable is used to respecify a contiguous portion of a color
     table previously defined using fglColorTable.  The pixels referenced by
     data replace the portion of the existing table from indices start to
     $"start"~+~"count"~-~1$, inclusive.  This region may not include any
     entries outside the range of the color table as it was originally
     specified.	 It is not an error to specify a subtexture with width of 0,
     but such a specification has no effect.

NOTES
     fglColorSubTable is present only if GL_ARB_imaging is returned when
     fglGetString is called with an argument of GL_EXTENSIONS.

     GL_ABGR_EXT is valid only if the EXT_abgr extension is supported.

ERRORS
     GL_INVALID_ENUM is generated if target is not one of the allowable
     values.

     GL_INVALID_VALUE is generated if $"start"~+~"count"~>~width$.

     GL_INVALID_ENUM is generated if format is not one of the allowable
     values.

     GL_INVALID_ENUM is generated if type is not one of the allowable values.

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