Detailed Description

Functions for Gray-8 image conversions.

Function Documentation

SimdGrayToBgr()

void SimdGrayToBgr	(	const uint8_t *	gray,
		size_t	width,
		size_t	height,
		size_t	grayStride,
		uint8_t *	bgr,
		size_t	bgrStride
	)

Converts 8-bit gray image to 24-bit BGR image.

All images must have the same width and height.

Note

This function has a C++ wrapper Simd::GrayToBgr(const View<A>& gray, View<A>& bgr).

Parameters

[in]	gray	- a pointer to pixels data of input 8-bit gray image.
[in]	width	- an image width.
[in]	height	- an image height.
[in]	grayStride	- a row size of the gray image.
[out]	bgr	- a pointer to pixels data of output 24-bit BGR image.
[in]	bgrStride	- a row size of the bgr image.

SimdGrayToBgra()

void SimdGrayToBgra	(	const uint8_t *	gray,
		size_t	width,
		size_t	height,
		size_t	grayStride,
		uint8_t *	bgra,
		size_t	bgraStride,
		uint8_t	alpha
	)

Converts 8-bit gray image to 32-bit BGRA image.

All images must have the same width and height.

Note

This function has a C++ wrapper Simd::GrayToBgra(const View<A>& gray, View<A>& bgra, uint8_t alpha).

Parameters

[in]	gray	- a pointer to pixels data of input 8-bit gray image.
[in]	width	- an image width.
[in]	height	- an image height.
[in]	grayStride	- a row size of the gray 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.

GrayToBgr()

void GrayToBgr	(	const View< A > &	gray,
		View< A > &	bgr
	)

Converts 8-bit gray image to 24-bit BGR image.

All images must have the same width and height.

Note

This function is a C++ wrapper for function SimdGrayToBgr.

Parameters

[in]	gray	- an input 8-bit gray image.
[out]	bgr	- an output 24-bit BGR image.

GrayToBgra()

void GrayToBgra	(	const View< A > &	gray,
		View< A > &	bgra,
		uint8_t	alpha = 0xFF
	)

Converts 8-bit gray image to 32-bit BGRA image.

All images must have the same width and height.

Note

This function is a C++ wrapper for function SimdGrayToBgra.

Parameters

[in]	gray	- an input 8-bit gray image.
[out]	bgra	- an output 32-bit BGRA image.
[in]	alpha	- a value of alpha channel. It is equal to 255 by default.
