Constructor & Destructor Documentation

Rgba8 ( const Rgba8 &  )

default

Default copy constructor.

Rgba8 ( Rgba8 &&  )

default

Default move constructor.

Rgba8 ( )

inline

Default ctor initializes all channels to zero.

Rgba8 ( uint8_t  r, uint8_t  g, uint8_t  b, uint8_t  a = 255u  )

inline

integer r,g,b,a ctor where alpha channel defaults to opaque

Note

all values should be in the range 0u to 255u

Rgba8 ( uint8_t  v )

inlineexplicit

ctor where all channels are initialized to the same value

Note

value should be in the range 0u to 255u

Rgba8 ( float  r, float  g, float  b, float  a = 1.0f  )

inline

floating-point r,g,b,a ctor where alpha channel defaults to opaque

Note

all values should be in the range 0.0f to 1.0f

Rgba8 ( const Vec3f &  rgb )

inline

Vec3f r,g,b ctor (alpha channel it set to 1)

Note

all values should be in the range 0.0f to 1.0f

Rgba8 ( const Vec4f &  rgba )

inline

Vec4f r,g,b,a ctor.

Note

all values should be in the range 0.0f to 1.0f
