, IppiMaskSize
mask
, IppDataType
srcDataType
, IppDataType
dstDataType
, int
numChannels
, int*
pBufferSize
);
Include Files
ippi.h
Parameters
dstRoiSize
Size of the destination ROI in pixels.
mask
Predefined mask of
IppiMaskSize
type. Possible value is
ippMskSize3x3
.
srcDataType
Data type of the source image.
dstDataType
Data type of the destination image.
numChannels
Number of channels in the image. Possible value is 1.
pBufferSize
Pointer to the size of the external work buffer.
Description
The
ippiFilterRobertsDownBorderGetBufferSize
function computes the size, in bytes, of the external work buffer needed for the
ippiFilterRobertsDownBorder
function. The result is stored in the
pBufferSize
parameter.
For an example on how to use this function, see the code example provided with the
ippiFilterRobertsDownBorder
function description.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when
pBufferSize
is NULL.
ippStsSizeErr
Indicates an error when
dstRoiSize
is negative, or equal to zero.
ippStsMaskSizeErr
Indicates an error when
mask
has an illegal value.
ippStsDataTypeErr
Indicates an error when
srcDataType
or
dstDataType
has an illegal value.
ippStsNumChannelsError
Indicates an error when
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.
