AS the matter of fact we only use 6 primary colors as ActiveText uses 44 * same hue as the background. 45 * 46 * Secondary colors : 47 * Menu colors : HighInactive, HighActive 48 * These should have same hue as Inactive1 and Active, but brightness 49 * at 10% higher. 50 * Menu text colors should be the same as InactiveText1 and ActiveText 51 * Menu disabled item's text color: DisabledText 52 * This one should have same hue as Inactive1, but saturation reduced 53 * to 5% level. 54 * 55 * Derived gradient colors 56 * Colors Background, Inactive1, Inactive2, Active, HighInactive, HighActive 57 * will have a 2 color gradient associated with them. To calculate these colors 58 * we add 10% and substract 10% to/from brightness of the respectable color. 59 * ____________________ 60 * 10 colors total: 6 primary colors and 4 derived colors 61 */ 62 63 #define ASMC_Base 0 64 #define ASMC_Inactive1 1 65 #define ASMC_Inactive2 2 66 #define ASMC_Active 3 67 #define ASMC_InactiveText1 4 68 #define ASMC_InactiveText2 5 69 70 #define ASMC_ActiveText 6 71 #define ASMC_HighInactive 7 72 #define ASMC_HighActive 8 73 #define ASMC_HighInactiveBack 9 74 #define ASMC_HighActiveBack 10 75 #define ASMC_HighInactiveText 11 76 #define ASMC_HighActiveText 12 77 #define ASMC_DisabledText 13 78 79 #define ASMC_BaseDark 14 80 #define ASMC_BaseLight 15 81 #define ASMC_Inactive1Dark 16 82 #define ASMC_Inactive1Light 17 83 #define ASMC_Inactive2Dark 18 84 #define ASMC_Inactive2Light 19 85 #define ASMC_ActiveDark 20 86 #define ASMC_ActiveLight 21 87 #define ASMC_HighInactiveDark 22 88 #define ASMC_HighInactiveLight 23 89 #define ASMC_HighActiveDark 24 90 #define ASMC_HighActiveLight 25 91 #define ASMC_HighInactiveBackDark 26 92 #define ASMC_HighInactiveBackLight 27 93 #define ASMC_HighActiveBackDark 28 94 #define ASMC_HighActiveBackLight 29 95 #define ASMC_Cursor 30 96 #define ASMC_MainColors 31 97 98 99 extern char *ASMainColorNames[ASMC_MainColors]; 100 101 typedef struct ASColorScheme 102 { 103 int angle ; 104 105 ASFlagType set_main_colors ; /* set bits represent colors 106 * set manually, instead of 107 * being computed from the 108 * base color */ 109 int main_saturations[ASMC_MainColors] ; 110 int main_values[ASMC_MainColors] ; 111 int main_hues[ASMC_MainColors] ; 112 ARGB32 main_colors[ASMC_MainColors] ; 113 114 }ASColorScheme; 115 116 #define ASCS_MIN_ANGLE 5 117 #define ASCS_MAX_ANGLE 60 118 #define ASCS_DEFAULT_ANGLE 15 119 120 #define ASCS_MAX_BRIGHTNESS 100 121 #define ASCS_MAX_SATURATION 100 122 #define ASCS_MAX_HUE 360 123 #define ASCS_MAX_COLD_HUE 300 124 #define ASCS_MIN_COLD_HUE 120 125 126 #define ASCS_COLD_SATURATION_OFFSET 20 127 128 #define ASCS_MAX_PRIMARY_BRIGHTNESS 70 129 #define ASCS_MIN_PRIMARY_BRIGHTNESS 30 130 #define ASCS_MIN_PRIMARY_SATURATION 10 131 132 #define ASCS_WHITING_SATURATION_LEVEL 2 133 #define ASCS_WHITING_MIN_BRIGHTNESS_LEVEL 90 134 #define ASCS_WHITING_ACTV_MIN_BRIGHT_LEVEL 98 135 #define ASCS_BLACKING_BRIGHTNESS_LEVEL 10 136 137 #define ASCS_BLACK_O_WHITE_CRITERIA16_VAL(r16,g16,b16) (( ((CARD32)(r16)) *222+((CARD32)(g16))*707+((CARD32)(b16)) *71)/1000) 138 #define ASCS_BLACK_O_WHITE_CRITERIA16(r16,g16,b16) (ASCS_BLACK_O_WHITE_CRITERIA16_VAL(r16,g16,b16)>0x09FFF) 139 140 #define ASCS_NORMAL_BRIGHTNESS_OFFSET 10 141 #define ASCS_HIGH_BRIGHTNESS_OFFSET 20 142 #define ASCS_DISABLED_SATURATION_LEVEL 20 143 #define ASCS_GRADIENT_BRIGHTNESS_OFFSET 20 144 #define ASCS_DISABLED_SATURATION_THRESHOLD 75 145 146 #define ASCS_MONO_MIN_SHADE 10 147 #define ASCS_MONO_MAX_SHADE 90 148 #define ASCS_MONO_MIN_BASE_SHADE 20 149 #define ASCS_MONO_MAX_BASE_SHADE 80 150 #define ASCS_MONO_CONTRAST_OFFSET 45 151 #define ASCS_MONO_TEXT_CONTRAST 65 152 #define ASCS_MONO_SIMILAR_OFFSET 15 153 #define ASCS_MONO_GRADIENT_OFFSET 15 154 #define ASCS_MONO_HIGH_OFFSET 5 155 156 157 158 ARGB32 make_color_scheme_argb( ASColorScheme *cs, int id, CARD32 base_alpha16, CARD32 hue360, CARD32 sat100, CARD32 val100 ); 159 void make_color_scheme_hsv( ARGB32 argb, int *phue, int *psat, int *pval ); 160 161 ASColorScheme *make_ascolor_scheme( ARGB32 base, int angle ); 162 #define make_default_ascolor_scheme() make_ascolor_scheme(DEFAULT_COLORSCHEME_BASE,ASCS_DEFAULT_ANGLE) 163 ASColorScheme *make_NeXTish_ascolor_scheme(); 164 165 166 void populate_ascs_colors_rgb( ASColorScheme *cs ); 167 void populate_ascs_colors_xml( ASColorScheme *cs ); 168 169 170 #ifdef __cplusplus 171 } 172 #endif 173 174 175 176 #endif 177 178
