DCTFwdGetBufSize

Computes the size of the forward DCT work buffer.

Syntax

IppStatus ippsDCTFwdGetBufSize_32f(const IppsDCTFwdSpec_32f* pDCTSpec, int* pBufferSize);

IppStatus ippsDCTFwdGetBufSize_16s(const IppsDCTFwdSpec_16s* pDCTSpec, int* pBufferSize);

IppStatus ippsDCTFwdGetBufSize_64f(const IppsDCTFwdSpec_64f* pDCTSpec, int* pBufferSize);

Parameters

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

Description

The function ippsDCTFwdGetBufSize is declared in the ipps.h file. This function computes in bytes the size pBufferSize of the work buffer for the forward 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.
