                                             gdouble black);

Very basic initialiser for the internal GimpCMYK structure. Channel values are doubles in the range 0 to 1.

gimp_cmyk_set_uchar ()

void        gimp_cmyk_set_uchar             (GimpCMYK *cmyk,

                                             guchar black);

The same as gimp_cmyk_set(), except that channel values are unsigned chars in the range 0 to 255.

gimp_cmyk_get_uchar ()

void        gimp_cmyk_get_uchar             (const GimpCMYK *cmyk,

                                             gdouble yellow,
                                             gdouble black,
                                             gdouble alpha);

Initialiser for the internal GimpCMYK structure. Channel values are doubles in the range 0 to 1.

gimp_cmyka_set_uchar ()

void        gimp_cmyka_set_uchar            (GimpCMYK *cmyka,
                                             guchar cyan,

                                             guchar alpha);

The same as gimp_cmyka_set(), except that channel values are unsigned chars in the range 0 to 255.

gimp_cmyka_get_uchar ()

void        gimp_cmyka_get_uchar            (const GimpCMYK *cmyka,
                                             guchar *cyan,
