Detailed Description

32-bit BGRA pixel.

Provides manipulation of 32-bit BGRA (Blue, Green, Red, Alpha) pixels of the View struct.

Constructor & Destructor Documentation

SIMD_INLINE Bgra32 ( const uint8_t &  gray = uint8_t(0),
const uint8_t &  a = uint8_t(255) 
)

Creates a new 32-bit BGRA pixel structure with specified channel values.

Parameters
[in]gray- initial value for blue, green and red channels. It is equal to 0 by default.
[in]a- initial value for alpha channel. It is equal to 255 by default.
SIMD_INLINE Bgra32 ( const uint8_t &  b,
const uint8_t &  g,
const uint8_t &  r,
const uint8_t &  a = uint8_t(255) 
)

Creates a new 32-bit BGRA pixel structure with specified channel values.

Parameters
[in]b- initial value for blue channel.
[in]g- initial value for green channel.
[in]r- initial value for red channel.
[in]a- initial value for alpha channel. It is equal to 255 by default.
SIMD_INLINE Bgra32 ( const Bgr24 p,
const uint8_t &  a = uint8_t(255) 
)

Creates a new 32-bit BGRA pixel structure on the base of 32-bit BGR pixel.

Parameters
[in]p- 32-bit BGR pixel.
[in]a- initial value for alpha channel. It is equal to 255 by default.
SIMD_INLINE Bgra32 ( const Bgra32 p)

Creates a copy of 32-bit BGRA pixel structure.

Parameters
[in]p- 32-bit BGRA pixel.
