Constructor & Destructor Documentation

RGBA() [1/2]

KTech::RGBA::RGBA ( uint8_t red = 0, uint8_t green = 0, uint8_t blue = 0, uint8_t alpha = 0 )

inlineconstexpr

Construct an RGBA color.

Parameters

[in]	red	Red primary color.
[in]	green	Green primary color.
[in]	blue	Blue primary color.
[in]	alpha	Alpha channel.

RGBA() [2/2]

KTech::RGBA::RGBA ( RGB rgb, uint8_t alpha )

inlineconstexpr

Construct an RGBA color from an RGB color.

Parameters

[in]	rgb	RGB base.
[in]	alpha	Alpha channel.

Member Function Documentation

operator==()

auto KTech::RGBA::operator== ( const RGBA & rgba ) const -> bool

inlineconstexpr

Compare 2 RGBAs.

Parameters

[in]

rgba

The RGBA to compare with this RGBA.

Returns

true: the alpha channel, red, green and blue primary colors are equal. false: they are unequal.
