Color

Instantiates to a color type. FieldTuple is the color specifier, as parsed by the FieldList template from ae.utils.meta. By convention, each field's name indicates its purpose: - x: padding - a: alpha - l: lightness (or grey, for monochrome images) - others (r, g, b, etc.): color information

Static functions

blend typeof(this) blend(typeof(this) c0, typeof(this) c1): Alpha-blend two colors.
fromHex typeof(this) fromHex(char[] s): Construct an RGB color from a typical hex string.
itpl typeof(this) itpl(typeof(this) c0, typeof(this) c1, P p, P p0, P p1): Interpolate between two colors.
monochrome typeof(this) monochrome(ChannelType value): Return a Color instance with all fields set to "value".
