Detailed Description

Color structure, in RGBA or HSVA format.

This class is used to represent a Color, either in RGBA or HSVA format. It inherits from std::array<float,4> and provides methods to convert between different color models.

For RGBA, the values are in the range [0,255].

For HSVA, the values are in the range [0,360] for hue and [0,100] for saturation, value and alpha.

Predefined Colors are also available.

Constructor & Destructor Documentation

Color() [1/5]

codac2::Color::Color ( )

explicit

Default constructor.

All values are set to 0

Color() [2/5]

codac2::Color::Color ( const std::array< float, 3 > & xyz, Model m_ = Model::RGB )

explicit

Constructor from an array of 3 floats.

Parameters

xyz	Array of 3 floats (RGB or HSV values)
m_	Color model (RGB or HSV)

Color() [3/5]

codac2::Color::Color ( const std::array< float, 4 > & xyza, Model m_ = Model::RGB )

explicit

Constructor from an array of 4 floats.

Parameters

xyza	Array of 4 floats (RGBA or HSVA values)
m_	Color model (RGB or HSV)

Color() [4/5]

codac2::Color::Color ( const std::initializer_list< float > xyza, Model m_ = Model::RGB )

explicit

Constructor from an initializer list of floats.

Parameters

xyza	Initializer list of floats (RGB, RGBA, HSV or HSVA values)
m_	Color model (RGB or HSV)

Color() [5/5]

codac2::Color::Color ( const std::string & hex_str )

explicit

Constructor from a hex string.

Parameters

hex_str

Hex string in html format (e.g. #ff0000 or #ff0000ff)
