		size_t	redStride,
		uint8_t *	bgra,
		size_t	bgraStride,
		uint8_t	alpha
	)

Converts 48-bit planar BGR image to 32-bit BGRA image.

All images must have the same width and height.

Note

This function has a C++ wrapper Simd::Bgr48pToBgra32(const View<A>& blue, const View<A>& green, const View<A>& red, View<A>& bgra, uint8_t alpha).

Parameters

[in]	blue	- a pointer to pixels data of input 16-bit image with blue color plane.
[in]	blueStride	- a row size of the blue image.
[in]	width	- an image width.
[in]	height	- an image height.
[in]	green	- a pointer to pixels data of input 16-bit image with green color plane.
[in]	greenStride	- a row size of the blue image.
[in]	red	- a pointer to pixels data of input 16-bit image with red color plane.
[in]	redStride	- a row size of the red image.
[out]	bgra	- a pointer to pixels data of output 32-bit BGRA image.
[in]	bgraStride	- a row size of the bgra image.
[in]	alpha	- a value of alpha channel.

SimdFloat32ToUint8()

void SimdFloat32ToUint8	(	const float *	src,
		size_t	size,
		const float *	lower,
		const float *	upper,
		uint8_t *	dst
	)

Converts numbers in the array from 32-bit float to 8-bit unsigned integer format.

For every element:

dst[i] = (min(max(src[i], lower), upper) - lower)*255/(upper - lower);

Parameters

[in]	src	- a pointer to the input array with 32-bit float point numbers.
[in]	size	- a size of input and output array.
[in]	lower	- a pointer to lower saturated bound of the input array.
[in]	upper	- a pointer to upper saturated bound of the input array.
[out]	dst	- a pointer to the output array with 8-bit unsigned integer numbers.

SimdUint8ToFloat32()

void SimdUint8ToFloat32	(	const uint8_t *	src,
		size_t	size,
		const float *	lower,
		const float *	upper,
		float *	dst
	)

Converts numbers in the array from 8-bit unsigned integer to 32-bit float format.

For every element:

dst[i] = src[i]*(upper - lower)/255 + lower;

Parameters

[in]	src	- a pointer to the input array with 8-bit unsigned integer numbers.
[in]	size	- a size of input and output array.
[in]	lower	- a pointer to lower bound of the output array.
[in]	upper	- a pointer to upper bound of the output array.
[out]	dst	- a pointer to the output array with 32-bit float point numbers.

SimdInt16ToGray()

void SimdInt16ToGray	(	const uint8_t *	src,
		size_t	width,
		size_t	height,
		size_t	srcStride,
		uint8_t *	dst,
		size_t	dstStride
	)

Converts 16-bit signed integer image to 8-bit gray image with saturation.

All images must have the same width and height.

For every point:

dst[i] = Max(0, Min(255, src[i]));

Note

This function has a C++ wrapper Simd::Int16ToGray(const View<A> & src, View<A> & dst).

Parameters

[in]	src	- a pointer to pixels data of input 16-bit signed integer image.
[in]	width	- an image width.
[in]	height	- an image height.
[in]	srcStride	- a row size of the 16-bit signed integer image.
[out]	dst	- a pointer to pixels data of input 8-bit gray image.
[out]	dstStride	- a row size of the gray image.

		const View< A > &	red,
		View< A > &	bgra,
		uint8_t	alpha = 0xFF
	)

Converts 48-bit planar BGR image to 32-bit BGRA image.

All images must have the same width and height.

Note
