Parameters
roiSize
Maximum size of the destination ROI in pixels.
maskSize
Size of the filter mask in pixels.
dataType
Data type of the image. Possible values are:
ipp8u
,
ipp16s
,
ipp16u
, and
ipp32f
numChannels
Number of channels in the image. Possible values are 1, 3, and 4.
pBufferSize
Pointer to the size, in bytes, of the external work buffer.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function computes the size, in bytes, of the external work buffer for the
ippiSumWindow
function. The result is stored in the
pBufferSize
parameter.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsSizeErr
Indicates an error if
roiSize
has a field with a zero or negative value.
ippStsMaskSizeErr
Indicates an error if
maskSize
has an illegal value.
ippStsDataTypeErr
Indicates an error if
dataType
has an illegal value.
ippStsNumChannelsError
Indicates an error 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.
