ZFP Compression Functions

This section describes the Intel® Integrated Performance Primitives data compression functions that implement the ZFP compressed data format. You can use the ZFP algorithm to perform lossy compression of 3D floating point data. The ZFP format and algorithm are described in [ZFP].

• EncodeZfpGetStateSize
  Calculates the size of the buffer for the ZFP compression structure.
• EncodeZfpInit, EncodeZfpInitLong
  Initializes the ZFP compression structure with default values.
• EncodeZfpSet
  Populates fields of the ZFP compression structure with input values.
• EncodeZfpSetAccuracy
  Sets the desired precision value in the ZFP compression structure.
• EncodeZfp444
  Encodes a 4x4x4 block of 3D floating point data.
• EncodeZfpGetCompressedBitSize
  Returns the current compressed data size.
• EncodeZfpFlush
  Writes any buffered encoded data from the ZFP compression structure to the destination buffer.
• EncodeZfpGetCompressedSize, EncodeZfpGetCompressedSizeLong
  Returns the current compressed data size.
• DecodeZfpGetStateSize
  Calculates the size of the buffer for the ZFP decompression structure.
• DecodeZfpInit, DecodeZfpInitLong
  Initializes the ZFP decompression structure with default values.
• DecodeZfpSet
  Populates fields of the ZFP decompression structure with input values.
• DecodeZfpSetAccuracy
  Sets the desired precision value in the ZFP decompression structure.
• DecodeZfp444
  Decodes a 4x4x4 block of 3D floating point data.
• DecodeZfpGetCompressedSize, DecodeZfpGetCompressedSizeLong
  Returns the current decompressed data size.
