WTGetBufSize_B53

Computes the size of the buffer for wavelet transform with reversible filter.

Syntax

IppStatus ippiWTGetBufSize_B53_JPEG2K_16s_C1R(const IppiRect* pTileRect, int* pSize);

IppStatus ippiWTGetBufSize_B53_JPEG2K_32s_C1R(const IppiRect* pTileRect, int* pSize);

IppStatus ippiWTGetBufSize_B53_JPEG2K_16s_C1IR(const IppiRect* pTileRect, int* pSize);

IppStatus ippiWTGetBufSize_B53_JPEG2K_32s_C1IR(const IppiRect* pTileRect, int* pSize);

Parameters

pTileRect	Pointer to the tile rectangle structure.
pSize	Pointer to the computed value of the buffer.

Description

The function ippiWTGetBufSize_B53_JPEG2K is declared in the ippj.h file. This function computes the size in bytes of the work buffer that is required for a tile-oriented wavelet transform functions ippiWTFwd_B53_JPEG2K and ippiWTInv_B53_JPEG2K.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error condition if any of the specified pointers is NULL.
