XcmsConvertColors(3)						  XLIB FUNCTIONS					      XcmsConvertColors(3)

NAME

       XcmsConvertColors - convert CCC color specifications

SYNTAX

       Status XcmsConvertColors(XcmsCCC ccc, XcmsColor colors_in_out[], unsigned int ncolors, XcmsColorFormat target_format, Bool compres-
	      sion_flags_return[]);

ARGUMENTS

       ccc	 Specifies the CCC.  If Conversion is between device-independent color spaces only (for example, TekHVC to CIELuv), the CCC is
		 necessary only to specify the Client White Point.

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

       compression_flags_return
		 Returns an array of Boolean values indicating compression status.  If a non-NULL pointer is supplied, each element of the array
		 is set to True if the corresponding color was compressed and False otherwise.	Pass NULL if the compression status is not useful.

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

       target_format
		 Specifies the target color specification format.

DESCRIPTION

       The XcmsConvertColors function converts the color specifications in the specified array of XcmsColor structures from their current format
       to a single target format, using the specified CCC.  When the return value is XcmsFailure, the contents of the color specification array
       are left unchanged.

       The array may contain a mixture of color specification formats (for example, 3 CIE XYZ, 2 CIE Luv, and so on).  When the array contains
       both device-independent and device-dependent color specifications and the target_format argument specifies a device-dependent format (for
       example, XcmsRGBiFormat, XcmsRGBFormat), all specifications are converted to CIE XYZ format and then to the target device-dependent format.

Name
  XcmsConvertColors - convert color specifications in XcmsColor structures to another color space specific encoding.

Synopsis
  Status XcmsConvertColors(ccc, colors_in_out, ncolors, target_format,
  compression_flags_return)
	XcmsCCC ccc;
	XcmsColor colors_in_out[];
	unsigned int ncolors;
	XcmsColorFormat target_format;
	Bool compression_flags_return[];

Arguments
  ccc	     Specifies	the  color conversion context.	If conversion is between device-independent color spaces only (for example, TekHVC to
	     CIELuv), the CCC is necessary only to specify the Client White Point.

  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.

  target_format
	     Specifies the target color specification format.

  compression_flags_return
	     Specifies an array of ncolors Boolean values for returning compression status of each color conversion.  If a  non-NULL  pointer
	     is  supplied,  each  element  in  the  array is set to True if the corresponding color in the color specification array was com-
	     pressed, and False otherwise.  Pass NULL if the compression status is not useful.

Returns
  Zero on failure, non-zero on success.

Availability
  Release 5 and later.

Description
  The XcmsConvertColors() function converts the color specifications in the specified array of XcmsColor structures from their current format
  (which  may  vary  from element to element of the array) to a single target format using the specified CCC.  If all the conversions succeed
  without gamut compression, XcmsConvertColors() returns XcmsSuccess.  If one or more of the  conversions  required  gamut  compression,  the
  function  returns  XcmsSuccessWithCompression, and sets the appropriate flags in compression_flags_return array.  If any of the conversions
  fail, the function returns XcmsFailure and the contents of the color specification array are left unchanged.

Structures
  The XcmsColor and XcmsColorFormat structures are shown on the XcmsColor reference page.
