ParseColorName()

unsigned ParseColorName

(

std::string_view

s

)

ParseColorName() parses the given string and returns a corresponding RGB color as a 24-bit integer.

Recognized formats are: #RGB (each color channel is 4-bit hexadecimal number; range: 0-F) #RRGGBB (each color channel is 8-bit hexadecimal number; range: 00-FF) rgb:R/G/B (each color channel is 4-bit hexadecimal number; range: 0-F) rgbi:1/1/1 (each color channel is a decimal floating point value; range: 0-1) gold (color names recognized by X11 are recognized, case sensitive) Anything else produces undefined results.
