1180 | If Xft support has been compiled in and as long as Xft/Xrender/X don't |
|
|

|
|
1182 | "rgba:rrrr/gggg/bbbb/aaaa" (recommended, but MUST have 4 |
|
|
1183 | digits/component), "#ARGB", "#AARRGGBB" and "#AAAARRRRGGGGBBBB" colour |
|
|
1184 | specifications, in addition to the ones provided by X, where the |
|
|
1185 | additional A component specifies alpha (opacity) values (0 is completely |
|
|
1186 | transparent and the maximum is opaque). You probably need to specify |
|
|
1187 | "-depth 32", too, and have the luck that your X-server uses ARGB pixel |
|
|
1188 | layout, as X is far from just supporting ARGB visuals out of the box, |
|
|
1189 | and rxvt-unicode just fudges around. |

|
1194 | provided by X, where the additional A component specifies opacity |
|
|
1195 | (alpha) values. The minimum value of 0 is completely transparent). You |
|
|
1196 | can also prefix any color with "[a]", where "a" is on to four hex digits |
|
|
1197 | specifiying the opacity value. |

1203 | For example, the following selects an almost completely transparent red |
|

|
1206 | rxvt -depth 32 -bg rgba:0000/0000/0000/2222 -fg "[e]pink" |
