A colour model + is specified with a value of + + typedef enum libcolour_model libcolour_model_t; + + The colour models can listed using the macros + + LIBCOLOUR_LIST_MODELS(IMACRO, TYPE_AFFIX) + + or + + LIBCOLOUR_LIST_MODELS_N(MACRO, TYPE_AFFIX, ...) + + where MACRO is the macro that shall be expanded, and + TYPE_AFFIX shall be f, lf, or llf for float-typed, + double-typed, and long double-typed colour module stuctures, + respectively. LIBCOLOUR_LIST_MODELS expands MACRO with three + parameters: enum libcolour_model value of the colour model, + typedef-name of struct used to store colours of the colour + model, and the name of the member in union libcolour_colour_f, + union libcolour_colour_lf, and union libcolour_colour_llf that + is used to store a colour with the colour model. + LIBCOLOUR_LIST_MODELS_N is identical to LIBCOLOUR_LIST_MODELS + except allows the programmer to specify additional parameters + to pass MACRO when it is expanded. + + There there are three structs defined for each colour model, + the first member in each struct is + + enum libcolour_model model; + + The three structs for each colour model are for different data + types: float, double, and long double. For example, for sRGB, + the follow structs are defined: + + typedef struct libcolour_srgb_f libcolour_srgb_f_t; + typedef struct libcolour_srgb_lf libcolour_srgb_lf_t; + typedef struct libcolour_srgb_llf libcolour_srgb_llf_t; + + for float, double, and long double, respectively. Similarly, + + typedef union libcolour_colour_f libcolour_colour_f_t; + typedef union libcolour_colour_lf libcolour_colour_lf_t; + typedef union libcolour_colour_llf libcolour_colour_llf_t; + + are used for float, double, long double, respectively, and all + have the member + + enum libcolour_model model; + + The structs are not padded to be of the same size. + + <libcolour.h> defines structs the following for colour models: + + Generic RGB + See LIBCOLOUR_RGB(7). + + Standard RGB + See LIBCOLOUR_SRGB(7). + + CIE xyY + See LIBCOLOUR_CIEXYY(7). + + CIE 1931 XYZ + See LIBCOLOUR_CIEXYZ(7). + + CIE L*a*b* + See LIBCOLOUR_CIELAB(7). + + CIE 1976 (L*, u*, v*) + See LIBCOLOUR_CIELUV(7). + + CIE LChuv (also known as CIE HLCuv) + See LIBCOLOUR_CIELCHUV(7). + + YIQ + See LIBCOLOUR_YIQ(7). + + YDbDr + See LIBCOLOUR_YDBDR(7). + + YUV + See LIBCOLOUR_YUV(7). + + YPBPR + See LIBCOLOUR_YPBPR(7). + + YCgCo + See LIBCOLOUR_YCGCO(7). + + CIE 1960 UCS + See LIBCOLOUR_CIE1960UCS(7). + + CIE 1964 (U*, V*, W*) + See LIBCOLOUR_CIEUVW(7). + +ILLUMINANTS + libcolour provides a number of initialiser macros for standard + illuminants.
