DecodeZfp444

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

Syntax

Parameters

pState	Pointer to the ZFP decompression structure.
pDst	Pointer to the value at the coordinates (0, 0, 0) of the 3D destination buffer.
dstStep	Row step in bytes.
dstPlaneStep	Plane step in bytes.

Description

This function decodes a 4x4x4 block of 3D floating point data. The source data pointer is initialized by calling DecodeZfpInit and is updated automatically.

The function arranges the decompressed 3D data in the destination buffer in such a way that for any set of coordinates (x, y, z) within the 4x4x4 block,

pXYZ = (float *)((char *)pDst + x + y * dstStep + z * dstPlaneStep)

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 the ZFP decompression structure data is invalid.
