Function Documentation

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.
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.
