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 y;           /* 0.0 to ~.85 */
         XcmsFloat Y;           /* 0.0 to 1.0 */

         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 */
         XcmsFloat C;           /* 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.
