Color-klassen

Egendefinerte farger

Klikk her å velge farge:

Du kan enten lagre fargen i en egen variabel:

TDT4102::Color chosenColor(100, 100, 100);

Eller bruke verdien direkte, for eksempel som verdi av en funksjonsparameter:

TDT4102::Color(100, 100, 100)

Farger kan representeres på forskjellige måter. Det mest vanlige formatet er RGB (Rødt, Grønt, Blått). De ulike kanalene blandes i forskjellige mengder for å lage farger. Disse pleier å være verdier mellom 0 og 255 og det er de som brukes i Color-klassen. Prøv å velge hvit og deretter svart, og se hva som skjer med RGB-verdiene!

unsigned char redChannel = 0;
unsigned char greenChannel = 0;
unsigned char blueChannel = 0;
TDT4102::Color chosenColor(redChannel, greenChannel, blueChannel);

Forhåndsdefinerte farger

Det er vanligvis lettere å bruke en forhåndsdefinert farge i stedet for å måtte lete etter RGB verdier. Derfor har vi forhåndsdefinert en rekke farger. Fargeverdiene du kan velge fra er vist i tabellen under.
