SADGetBufferSize

Computes the size of the work buffer for the ippiSAD function.

Syntax

IppStatus ippiSADGetBufferSize(IppiSize srcRoiSize, IppiSize tplRoiSize, IppDataType dataType, int numChannels, IppiROIShape shape, int* pBufferSize);

Libraries: ippcore.lib, ippvm.lib, ipps.lib

Parameters

srcRoiSize	Size of the source ROI in pixels.
tplRoiSize	Size of the template ROI in pixels.
shape	Enumeration that defines the shape of the result of the SAD operation (see Structures and Enumerators).
dataType	Type of the input data.
numChannels	Number of channels in the images.
pBufferSize	Pointer to the computed value of the external buffer size.

Description

The ippiSADGetBufferSize function computes the size of the external work buffer (in bytes) needed for the ippiSAD function and stores the result in the *pBufferSize parameter.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr	Indicates an error condition if the pBufferSize pointer is NULL.
ippStsSizeErr	Indicates an error condition if srcRoiSize or tplRoiSize has a field with a zero or negative value.
ippStsNotSupportedModeErr	Indicates an error condition if either shape does not equal ippiROIValid or numChannels does not equal 1.
