Detailed Description

Represents as 32-bit RGBA color, with each component in the range [0, 255].

To construct, with an alpha channel:

RGBA(r, g, b, a);

With no alpha:

RGBA::RGB(r, g, b);

Member Function Documentation

toHexString()

std::string donner::css::RGBA::toHexString

(

)

const

Convert the color to a hex string, such as #ff0000.

Returns

'#rrggbb' if the color is opaque, or '#rrggbbaa' if the color has an alpha channel.
