Parameters
kernelSize
Size of the rectangular kernel in pixels.
dataType
Data type of the source image. Possible values are
Ipp8u
,
Ipp16s
,
Ipp16u
,
Ipp32f

numChannels
Number of channels in the image. Possible values are 1, 3, and 4.
pSpecSize
Pointer to the size of the filter specification structure.
Description
This function computes the size of the filter specification structure
pSpec
. Call this function before using the
ippiFilterSeparableInit
function.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error.
ippStsNullPtrErr
Indicates an error condition if one of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error condition if
kernelSize
has a field with a zero or negative value.
ippStsDataTypeErr
Indicates an error condition if
dataType
has an illegal value.
ippStsChannelErr
Indicates an error condition if
numChannels
has an illegal value.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
