Constructor & Destructor Documentation

Bgra32() [1/4]

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.

Bgra32() [2/4]

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.

Bgra32() [3/4]

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.

Member Function Documentation

At() [1/2]

template< template< class > class A > static const Bgr32 & At ( const View< A > &  view, ptrdiff_t  col, ptrdiff_t  row  )

static

Gets constant reference to the pixel with specific coordinates at the image view.

Parameters

Parameters

[in]	view	- an image view of 32-bit BGRA pixel format.
[in]	col	- x-coordinate of the pixel.
[in]	row	- y-coordinate of the pixel.

Returns

a reference to the pixel.
