DCTInvGetBufSize

Computes the size of the inverse DCT work buffer.

Syntax

IppStatus ippsDCTInvGetBufSize_16s(const IppsDCTInvSpec_16s* pDCTSpec, int* pBufferSize);

IppStatus ippsDCTInvGetBufSize_32f(const IppsDCTInvSpec_32f* pDCTSpec, int* pBufferSize);

IppStatus ippsDCTInvGetBufSize_64f(const IppsDCTInvSpec_64f* pDCTSpec, int* pBufferSize);

Parameters

pDCTSpec	Pointer to the DCT specification structure.
pBufferSize	Pointer to the DCT work buffer size value.

Description

The function ippsDCTInvGetBufSize is declared in the ipps.h file. This function computes in bytes the size pBufferSize of the work buffer for the inverse DCT specified by the structure pDCTSpec.

Return Values

ippStsNoErr	Indicates no error.
ippStsNullPtrErr	Indicates an error when the pDCTSpec pointer is NULL.
ippStsContextMatchErr	Indicates an error when the specification identifier pDCTSpec is incorrect.
