NAME

       XcmsConvertColors - convert CCC color specifications

SYNTAX

       Status  XcmsConvertColors(XcmsCCC  ccc,  XcmsColor colors_in_out[], unsigned int ncolors, XcmsColorFormat
              target_format, Bool compression_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.
