Hexadecimal number (colour) in string form.
Whether or not to accept the rrggbb string in lowercase letters.
A Voldemort struct with r, g and b members,
import std.conv : text; { auto rgb = rgbFromHex("000102"); assert((rgb.r == 0), rgb.r.text); assert((rgb.g == 1), rgb.g.text); assert((rgb.b == 2), rgb.b.text); } { auto rgb = rgbFromHex("#FFFFFF"); assert((rgb.r == 255), rgb.r.text); assert((rgb.g == 255), rgb.g.text); assert((rgb.b == 255), rgb.b.text); } { auto rgb = rgbFromHex("#3C507D"); assert((rgb.r == 60), rgb.r.text); assert((rgb.g == 80), rgb.b.text); assert((rgb.b == 125), rgb.b.text); } { auto rgb = rgbFromHex("9a4B7c", Yes.acceptLowercase); assert((rgb.r == 154), rgb.r.text); assert((rgb.g == 75), rgb.g.text); assert((rgb.b == 124), rgb.b.text); }
Convenience wrapper that takes a hex string and populates a Voldemort struct with its RR, GG and BB components.
This is to be used when mapping a #RRGGBB colour to their decimal red/green/blue equivalents.
