Parameters
dstRoiSize
Size of the destination ROI in pixels.
mask
Predefined mask of
IppiMaskSize
type. Possible values are
ippMskSize3x3
or
ippMskSize5x5
.
normType
Normalization mode of
IppNormType
type.
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
ippiFilterSobelGetBufferSize
function computes the size, in bytes, of the external work buffer needed for the
ippiFilterSobel
function. The result is stored in the
pBufferSize
parameter.
For an example on how to use this functions, see the code example provided with the
ippiFilterSobel
function description.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when
pBufferSize
is NULL.
ippStsSizeErr
Indicates an error when
dstRoiSize
is less than, or equal to zero.
ippStsMaskSizeErr
Indicates an error when
mask
has an illegal value.
ippStsBadArgErr
Indicates an error when
normType
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.
