XcmsWhiteAdjustProc()					 XcmsWhiteAdjustProc()

Name
  XcmsWhiteAdjustProc  – interface definition for the white point adjust‐
  ment procedure.

Synopsis
  typedef Status (*XcmsWhiteAdjustProc)(ccc, initial_white_point,
  target_white_point, target_format, colors_in_out, ncolors,
  compression_flags_return)
	    XcmsCCC ccc;
	    XcmsColor *initial_white_point;
	    XcmsColor *target_white_point;
	    XcmsColorFormat target_format;
	    XcmsColor colors_in_out[];
	    unsigned int ncolors;
	    Bool compression_flags_return[];

Arguments
  ccc	    Specifies the color conversion context.

  initial_white_point
	    Specifies the initial white point.

  target_white_point
	    Specifies the target white point.

  target_format
	    Specifies the target color specification format.

  colors_in_out
	    Specifies an array of color	 specifications.   Pixel  members
	    are ignored and remain unchanged upon return.

  ncolors   Specifies  the  number  of	XcmsColor structures in the color
	    specification array.

  compression_flags_return
	    Specifies an array of Boolean values (or NULL)  for	 returned
	    information	 that indicates if the color was compressed.  For
	    example, if this routine  returns  XcmsSuccessWithCompression
	    and					       compression_flags_
	    return[3] is True, this indicates that the fourth color spec‐
	    ified  in  the  color specification array was compressed.  If
	    the calling routine is not interested in knowing which  color
	    was	 compressed  when the return value is XcmsSuccessWithCom‐
	    pression, it is allowed to pass a NULL for this argument.

Returns
  Zero on failure, non-zero on success.

Availability
  Release 5 and later.

Description
  XcmsWhiteAdjustProc is a function that takes the color  specifications,
  whose	 associated white point is initial_white_point, and modifies them
  for the target_white_point; returning the color specifications  in  the
  format specified by target_format.
