SimdShiftBilinear()

void SimdShiftBilinear	(	const uint8_t *	src,
		size_t	srcStride,
		size_t	width,
		size_t	height,
		size_t	channelCount,
		const uint8_t *	bkg,
		size_t	bkgStride,
		const double *	shiftX,
		const double *	shiftY,
		size_t	cropLeft,
		size_t	cropTop,
		size_t	cropRight,
		size_t	cropBottom,
		uint8_t *	dst,
		size_t	dstStride
	)

Performs shifting of input image with using bilinear interpolation.

All images must have the same width, height and format (8-bit gray, 16-bit UV, 24-bit BGR or 32-bit BGRA).

Note

This function has a C++ wrappers: Simd::ShiftBilinear(const View<A> & src, const View<A> & bkg, const Point<double> & shift, const Rectangle<ptrdiff_t> & crop, View<A> & dst).

Parameters

[in]	src	- a pointer to pixels data of the foreground input image.
[in]	srcStride	- a row size of the input image.
[in]	width	- an image width.
[in]	height	- an image height.
[in]	channelCount	- a channel count.
[in]	bkg	- a pointer to pixels data of the background input image.
[in]	bkgStride	- a row size of the background image.
[in]	shiftX	- an image shift along x axis.
[in]	shiftY	- an image shift along y axis.
[in]	cropLeft	- a crop left side.
[in]	cropTop	- a crop top side.
[in]	cropRight	- a crop right side.
[in]	cropBottom	- a crop bottom side.
[out]	dst	- a pointer to pixels data of the output image.
[in]	dstStride	- a row size of the output image.

ShiftBilinear()

void ShiftBilinear	(	const View< A > &	src,
		const View< A > &	bkg,
		const Point< double > &	shift,
		const Rectangle< ptrdiff_t > &	crop,
		View< A > &	dst
	)

Performs shifting of input image with using bilinear interpolation.

All images must have the same width, height and format (8-bit gray, 16-bit UV, 24-bit BGR or 32-bit BGRA).

Note

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

Parameters

[in]	src	- a foreground input image.
[in]	bkg	- a background input image.
[in]	shift	- an image shift.
[in]	crop	- a crop rectangle.
[out]	dst	- an output image.
