XcmsColor -- Xcms color structure

Structures

The structure for XcmsColor contains:
   typedef unsigned long XcmsColorFormat;  /* Color Specification Format */ 
   

typedef struct { union { XcmsRGB RGB; XcmsRGBi RGBi; XcmsCIEXYZ CIEXYZ; XcmsCIEuvY CIEuvY; XcmsCIExyY CIExyY; XcmsCIELab CIELab; XcmsCIELuv CIELuv; XcmsTekHVC TekHVC; XcmsPad Pad; } spec; unsigned long pixel; XcmsColorFormat format; } XcmsColor; /* Xcms Color Structure */

   typedef double XcmsFloat; 
   

typedef struct { unsigned short red; /* 0x0000 to 0xffff */ unsigned short green; /* 0x0000 to 0xffff */ unsigned short blue; /* 0x0000 to 0xffff */ } XcmsRGB; /* RGB Device */

   typedef struct {

   typedef struct { 
         XcmsFloat x;           /* 0.0 to ~.75 */

         XcmsFloat a_star; 
         XcmsFloat b_star; 
   } XcmsCIELab;                /* CIE L*a*b* */ 
   typedef struct { 
         XcmsFloat L_star;      /* 0.0 to 100.0 */ 
         XcmsFloat u_star; 
         XcmsFloat v_star; 
   } XcmsCIELuv;                /* CIE L*u*v* */ 
   typedef struct { 
         XcmsFloat H;           /* 0.0 to 360.0 */ 
         XcmsFloat V;           /* 0.0 to 100.0 */

   typedef struct { 
         XcmsFloat pad0; 
         XcmsFloat pad1; 
         XcmsFloat pad2; 
         XcmsFloat pad3; 
   } XcmsPad;                   /* four doubles */ 

Description

The XcmsColor structure contains a union of substructures, each supporting color specification encoding for a particular color space.
