Parameters
dstRoiSize
Size of the destination ROI, in pixels.
maskSize
Size of the filter kernel.
dataType
Data type of the source and destination images.
numChannels
Number of channels in the image. Possible values are 1, 3, or 4.
pBufferSize

Description
The
ippiFilterMaxBorderGetBufferSize
and
ippiFilterMinBorderGetBufferSize
functions compute the size, in bytes, of the external work buffer for the
ippiFilterMaxBorder
and
ippiFilterMinBorder
functions, respectively. The result is stored in the
pBufferSize
parameter.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error.
ippStsNullPtrErr
Indicates an error when
pBufferSize
is
NULL
.
ippStsSizeErr
Indicates an error when
dstRoiSize
has a field with a zero or negative value.
ippStsMaskSizeErr
Indicates an error when
maskSize
is less than, or e qual to zero.
ippStsDataTypeErr
Indicates an error when
dataType
has an illegal value.
ippStsNumChannelErr
Indicates an error when
numChannels
has an illegal value.
