EncodeRLE

Performs the bzip2-specific RLE.

Syntax

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

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

The function ippsEncodeRLE_BZ2 is declared in the ippdc.h file. 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 the functions ippsEncodeRLEInitAlloc_BZ2 or 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.
