Parameters

dstRoiSize	Size of the destination ROI in pixels.
maskSize	Size of the mask in pixels.
channels	Number of channels in the image.
pBufferSize	Pointer to the computed value of the external buffer size.

Description

This function computes the size in bytes of an external memory buffer that is required for the function ippiFilterWiener, and stores the result in the pBufferSize.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error.
ippStsNullPtrErr	Indicates an error condition if the pBufferSize pointer is NULL.
ippStsSizeErr	Indicates an error condition if one of the fields of dstRoiSize has a zero or negative value.
ippStsMaskSizeErr	Indicates an error condition if one of the fields of maskSize has a value less than or equal to 1.
ippStsNumChannelsErr	Indicates an error condition if channels is not 1, 3 or 4.
