Detailed Description

Functions for RGB-24 image conversions.

Function Documentation

SimdRgbToBgra()

void SimdRgbToBgra	(	const uint8_t *	rgb,
		size_t	width,
		size_t	height,
		size_t	rgbStride,
		uint8_t *	bgra,
		size_t	bgraStride,
		uint8_t	alpha
	)

Converts 24-bit RGB image to 32-bit BGRA image. Also it can be used for 24-bit BGR to 32-bit RGBA conversion.

All images must have the same width and height.

Note

This function has C++ wrappers: Simd::RgbToBgra(const View<A>& rgb, View<A>& bgra, uint8_t alpha) and Simd::BgrToRgba(const View<A>& bgr, View<A>& rgba, uint8_t alpha).

Parameters

[in]	rgb	- a pointer to pixels data of input 24-bit RGB (or 24-bit BGR) image.
[in]	width	- an image width.
[in]	height	- an image height.
[in]	rgbStride	- a row size of the rgb image.
[out]	bgra	- a pointer to pixels data of output 32-bit BGRA (or 32-bit RGBA) image.
[in]	bgraStride	- a row size of the bgra image.
[in]	alpha	- a value of alpha channel.

SimdRgbToGray()

void SimdRgbToGray	(	const uint8_t *	rgb,
		size_t	width,
		size_t	height,
		size_t	rgbStride,
		uint8_t *	gray,
		size_t	grayStride
	)

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

All images must have the same width and height.

Note

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

Parameters

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

RgbToBgr()

void RgbToBgr	(	const View< A > &	rgb,
		View< A > &	bgr
	)

Converts 24-bit RGB image to 24-bit BGR image.

All images must have the same width and height.

Note

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

Parameters

[in]	rgb	- an input 24-bit RGB image.
[out]	bgr	- an output 24-bit BGR image.

RgbToBgra()

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

Converts 24-bit RGB image to 32-bit BGRA image.

All images must have the same width and height.

Note

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

Parameters

[in]	rgb	- an input 24-bit RGB image.
[out]	bgra	- an output 32-bit BGRA image.
[in]	alpha	- a value of alpha channel. It is equal to 256 by default.

RgbToGray()

void RgbToGray	(	const View< A > &	rgb,
		View< A > &	gray
	)

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

All images must have the same width and height.

Note

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

Parameters

[in]	rgb	- an input 24-bit RGB image.
[out]	gray	- an output 8-bit gray image.

RgbToRgba()

void RgbToRgba	(	const View< A > &	rgb,
		View< A > &	rgba,
		uint8_t	alpha = 0xFF
	)

Converts 24-bit RGB image to 32-bit RGBA image.

All images must have the same width and height.

Note

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

Parameters

[in]	rgb	- an input 24-bit RGB image.
[out]	rgba	- an output 32-bit RGBA image.
[in]	alpha	- a value of alpha channel. It is equal to 256 by default.
