Detailed Description

Functions for RGBA-32 image conversions.

Function Documentation

◆ SimdRgbaToGray()

void SimdRgbaToGray ( const uint8_t *  rgba,
size_t  width,
size_t  height,
size_t  rgbaStride,
uint8_t *  gray,
size_t  grayStride 
)

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

All images must have the same width and height.

Note
This function has a C++ wrapper Simd::RgbaToGray(const View<A>& rgba, View<A>& gray).
Parameters
[in]rgba- a pointer to pixels data of input 32-bit RGBA image.
[in]width- an image width.
[in]height- an image height.
[in]rgbaStride- a row size of the rgba image.
[out]gray- a pointer to pixels data of output 8-bit gray image.
[in]grayStride- a row size of the gray image.

◆ RgbaToBgr()

void RgbaToBgr ( const View< A > &  rgba,
View< A > &  bgr 
)

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

All images must have the same width and height.

Note
This function is a C++ wrapper for function SimdBgraToRgb.
Parameters
[in]rgba- an input 32-bit RGBA image.
[out]bgr- an output 24-bit RGB image.

◆ RgbaToBgra()

void RgbaToBgra ( const View< A > &  rgba,
View< A > &  bgra 
)

Converts 32-bit RGBA image to 32-bit BGRA image.

All images must have the same width and height.

Note
This function is a C++ wrapper for function SimdBgraToRgba.
Parameters
[in]rgba- an input 32-bit RGBA image.
[out]bgra- an output 32-bit BGRA image.

◆ RgbaToGray()

void RgbaToGray ( const View< A > &  rgba,
View< A > &  gray 
)

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

All images must have the same width and height.

Note
This function is a C++ wrapper for function SimdRgbaToGray.
Parameters
[in]rgba- an input 32-bit RGBA image.
[out]gray- an output 8-bit gray image.

◆ RgbaToRgb()

void RgbaToRgb ( const View< A > &  rgba,
View< A > &  rgb 
)

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

All images must have the same width and height.

Note
This function is a C++ wrapper for function SimdBgraToBgr.
Parameters
[in]rgba- an input 32-bit RGBA image.
[out]rgb- an output 24-bit RGB image.
