Constructors, destructors, conversion operators

Color() constexpr noexcept
Default constructor (transparent color)
Color(NoInitT) explicit noexcept

Three channels constructor.
Color(std::uint32_t red, std::uint32_t green, std::uint32_t blue, std::uint32_t alpha) constexpr noexcept
Four channels constructor.
Color(std::uint32_t hex) explicit

Public functions

auto Rgba() const -> std::uint32_t
Returns the color as a single RGBA unsigned integer.
auto Argb() const -> std::uint32_t
Returns the color as a single RGBA unsigned integer.
auto Abgr() const -> std::uint32_t
Returns the color as a single ABGR unsigned integer.
auto Bgra() const -> std::uint32_t
Returns the color as a single BGRA unsigned integer.
auto Data() const -> const std::uint8_t*
Returns color array.
auto Data() -> std::uint8_t*
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
void Set(std::uint32_t red, std::uint32_t green, std::uint32_t blue, std::uint32_t alpha) constexpr
Sets four color channels.
void Set(std::uint32_t red, std::uint32_t green, std::uint32_t blue)
Sets three color channels.
void Set(std::uint32_t hex)
Sets three color channels from a hexadecimal code.
void SetVec(const std::uint32_t channels[NumChannels])
Sets four color channels from an array.
void SetAlpha(std::uint32_t alpha)
Sets the alpha channel.
auto operator=(const Colorf& color) -> Color&
Assigns operator from a normalized float color.
auto operator==(const Color& color) const -> bool
auto operator!=(const Color& color) const -> bool
auto operator+=(const Color& v) -> Color&
auto operator-=(const Color& v) -> Color&
auto operator*=(const Color& color) -> Color&
auto operator*=(float scalar) -> Color&
Multiplies by a constant scalar.
auto operator+(const Color& color) const -> Color
auto operator-(const Color& color) const -> Color
auto operator*(const Color& color) const -> Color
auto operator*(float scalar) const -> Color
Multiplies by a constant scalar.
