EncodeRLE_BZ2

Performs the bzip2-specific RLE.

Syntax

IppStatus ippsEncodeRLE_BZ2_8u(Ipp8u** ppSrc, int* pSrcLen, Ipp8u* pDst, int* pDstLen, IppRLEState_BZ2* pRLEState);

Include Files

ippdc.h

Domain Dependencies

Headers: ippcore.h, ippvm.h, ipps.h

Libraries: ippcore.lib, ippvm.lib, ipps.lib

Parameters

ppSrc

Double pointer to the source buffer.

pSrcLen

Pointer to the length of the source buffer.

pDst

Pointer to the destination buffer.

pDstLen

Pointer to the length of the destination buffer.

pRLEState

Pointer to the bzip2-specific RLE state structure.

Description

This function performs RLE encoding with thresholding equal to 4. It processes the input data ppSrc and writes the results to the pDst buffer. The function uses the bzip2-specific RLE state structure pRLEState. This structure must be initialized by ippsEncodeRLEInit_BZ2 beforehand.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error if one of the pointers is NULL.

ippStsSizeErr

Indicates an error if length of the source or destination buffer is less than or equal to 0.

ippStsDstSizeLessExpected

Indicates a warning if size of the destination buffer is insufficient to store all output elements.
