- Predefined mask ofIppiMaskSizetype.
- pBufferSize
- Pointer to the buffer size.
Description
This function computes the size of the external buffer that is
required for the filter function
ippiFilterLowpassBorder
. The kernel of the filter is the matrix of
either 3x3 or 5x5 size that is specified by the parameter mask
(see Table “Types of the Fixed
Filter Functions”
). This buffer pBufferSize[0]
can be used to
filter an image whose width and height are equal to or less than corresponding
fields of roiSize
.Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition if thepBufferSizepointer isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas a field with a zero or negative value.
- ippStsMaskSizeErr
- Indicates an error condition ifmaskhas a wrong value.
