/*
// Name: ipprResize_"mode"
// Purpose: Performs RESIZE transform of the source volume
// by xFactor, yFactor, zFactor and xShift, yShift, zShift
// |X'| |xFactor 0 0 | |X| |xShift|
// |Y'| = | yFactor 0 | * |Y| + |yShift|
// |Z'| | 0 0 zFactor| |Z| |zShift|
// Parameters:
// pSrc pointer to source volume data (8u_C1V, 16u_C1V, 32f_C1V modes)
// or array of pointers to planes in source volume data
// srcVolume size of source volume
// srcStep step in every plane of source volume
// srcPlaneStep step between planes of source volume (8u_C1V, 16u_C1V, 32f_C1V modes)
// srcVOI volume of interest of source volume
// pDst pointer to destination volume data (8u_C1V and 16u_C1V modes)
// or array of pointers to planes in destination volume data
// dstStep step in every plane of destination volume
// dstPlaneStep step between planes of destination volume (8u_C1V, 16u_C1V, 32f_C1V modes)
// dstVOI volume of interest of destination volume
// xFactor they specify fraction of resizing in X direction
// yFactor they specify fraction of resizing in Y direction
// zFactor they specify fraction of resizing in Z direction
// xShift they specify shifts of resizing in X direction
// yShift they specify shifts of resizing in Y direction
// zShift they specify shifts of resizing in Z direction
// interpolation type of interpolation to perform for resizing the input volume:
// IPPI_INTER_NN nearest neighbor interpolation
// IPPI_INTER_LINEAR trilinear interpolation
// IPPI_INTER_CUBIC tricubic polynomial interpolation
// including two-parameter cubic filters:
// IPPI_INTER_CUBIC2P_BSPLINE B-spline filter (1, 0)
// IPPI_INTER_CUBIC2P_CATMULLROM Catmull-Rom filter (0, 1/2)
// IPPI_INTER_CUBIC2P_B05C03 special filter with parameters (1/2, 3/10)
// pBuffer pointer to work buffer
// Returns:
// ippStsNoErr no errors
// ippStsNullPtrErr pSrc == NULL or pDst == NULL or pBuffer == NULL
// ippStsSizeErr width or height or depth of volumes is less or equal zero
// ippStsWrongIntersectVOI VOI hasn't an intersection with the source or destination volume
// ippStsResizeFactorErr xFactor or yFactor or zFactor is less or equal zero
// ippStsInterpolationErr (interpolation != IPPI_INTER_NN) &&
// (interpolation != IPPI_INTER_LINEAR) &&
// (interpolation != IPPI_INTER_CUBIC) &&
// (interpolation != IPPI_INTER_CUBIC2P_BSPLINE) &&
// (interpolation != IPPI_INTER_CUBIC2P_CATMULLROM) &&
// (interpolation != IPPI_INTER_CUBIC2P_B05C03)
// Notes:
// "mode" are 8u_C1V or 16u_C1V or 32f_C1V or 8u_C1PV or 16u_C1PV or 32f_C1PV
