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 isNULL.
- ippStsContexMatchErr
- Indicates an error if ZFP compression structure data is invalid.
