| Examples |  kei_Liniefarb(); Farb c = Farb(0, 126, 255); Fuellfarb(c); Viereck(15, 20, 35, 60); Komazahl value = blau(c); // Sets "value" to "255" Fuellfarb(value); Viereck(50, 20, 35, 60); |

| Description | Extracts the blue value from a Farb, scaled to match current Farbmodus(). This value is always returned as a Komazahl so be careful not to assign it to an Ganzizahl value. The blau() function is easy to use and undestand, but is slower than another technique. To achieve the same results when working in Farbmodus(RGB, 255), but with greater speed, use a bit mask to remove the other Farb components. For example, the following two lines of code are equivalent: Komazahl r1 = blau(myColor); |
