#include <color.hpp>

Public Member Functions
	Color ()
	Constructs an opaque white color.
	Color (float r, float g, float b, float a)
	Constructs a color from 0-255 RGB values and an alpha.
	Color (float r, float g, float b)
	Constructs a fully opaque color from 0-255 RGB values.

Public Attributes
float	r = 0
	Red channel, normalized to [0, 1].
float	g = 0
	Green channel, normalized to [0, 1].
float	b = 0
	Blue channel, normalized to [0, 1].
float	a = 0
	Alpha channel in [0, 1].

Detailed Description

RGBA color stored as normalized floating-point components.

RGB channels are stored in the range [0, 1] (constructors accept 0-255 values and divide by 255), while alpha is stored directly in [0, 1].

Constructor & Destructor Documentation

Color() [1/3]

cangine::Color::Color ( )

inline

Constructs an opaque white color.

Color() [2/3]

cangine::Color::Color ( float  r, float  g, float  b, float  a  )

inline

Constructs a color from 0-255 RGB values and an alpha.

Parameters

r	Red channel in the range [0, 255].
g	Green channel in the range [0, 255].
b	Blue channel in the range [0, 255].
a	Alpha in the range [0, 1] (asserted).

Color() [3/3]

cangine::Color::Color ( float  r, float  g, float  b  )

inline

Constructs a fully opaque color from 0-255 RGB values.

Parameters

r	Red channel in the range [0, 255].
g	Green channel in the range [0, 255].
b	Blue channel in the range [0, 255].
