Computes the size of the buffer wavelet transform with irreversible filter

Syntax

IppStatus ippiWTGetBufSize_D97_JPEG2K_16s_C1R(const IppiRect* pTileRect, int* pSize);

IppStatus ippiWTGetBufSize_D97_JPEG2K_32s_C1R(const IppiRect* pTileRect, int* pSize);

IppStatus ippiWTGetBufSize_D97_JPEG2K_16s_C1IR(const IppiRect* pTileRect, int* pSize);

IppStatus ippiWTGetBufSize_D97_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_D97_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 irreversible wavelet transform functions ippiWTFwd_D97_JPEG2K and ippiWTInv_D97_JPEG2K.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error condition if at least one of the specified pointers is NULL.
