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. Den mest vanlige formen er RGB verdier (Rødt, Grønt, og Blått), og blandes i forskjellige mengder for å forme ønskede fargen. Disse pleier å være verdier mellom 0 og 255 for hver farge-kanal, og det er de som brukes i de Color verdiene overfor. Prøv å velge hvit og deretter svart, og se hva som skjer med de 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 langt lettere å bruke en forhåndsdefinert farge i stedet for å måtte lete etter RGB verdier (bleh) eller lignende. Derfor har vi forhåndsdefinert en rekke farger for dere. De fargeverdiene du kan velge fra er vist i tabellen under.
