EncodeZfp444

Encodes a 4x4x4 block of 3D floating point data.

Syntax

IppStatus ippsEncodeZfp444_32f(const Ipp32f* pSrc, int srcStep, int srcPlaneStep, IppEncodeZfpState_32f* pState);

Parameters

pSrc	Pointer to the value at the coordinates (0, 0, 0) of the 3D source data block.
srcStep	Row step in bytes.
srcPlaneStep	Plane step in bytes.
pState	Pointer to the ZFP compression structure.

Description

This function encodes a 3D 4x4x4 block of floating point values. The function adds the encoded data to an internal bit stream. The pointer to the bit stream is initialized by calling the EncodeZfpInit function and is updated automatically.

The 3D source data must be arranged in memory in such a way that for any set of coordinates (x, y, z) within the 4x4x4 block,

pXYZ = (float *)((char *)pSrc + x + y * srcStep + z * srcPlaneStep)

is a pointer to the value at (x, y, z).

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error if any of the pointers is NULL.
ippStsContexMatchErr	Indicates an error if ZFP compression structure data is invalid.
