Parameters
srcSize
Size of the source image, in pixels.
dstSize
Size of the destination image, in pixels.
dataType
Data type of the image. Supported values:
ipp8u
,
ipp16u
,
ipp16s
,
ipp32f
,
ipp64f
.
numChannels
Number of image channels. Possible values: 1, 3, or 4.
pSpec
Pointer to the specification structure for the resize filter.
pInitBuf
Pointer to the temporary buffer for initialization of the linear filter.
Description
This function initializes the
IppiResizeSpec_32f
structure for the resize operation with antialiasing using the linear interpolation method.
Before using this function, calculate the size of the temporary buffer and specification structure using the
ippiResizeGetSize
function with the
antialiasing
parameter equal to 1.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error when one of the specified pointers is
NULL
.
ippStsNoOperation
Indicates a warning when width or height of the image is equal to zero.
ippStsSizeErr
Indicates an error if width or height of the source or destination image is negative.
ippStsExceededSizeErr
Indicates an error If width or height of the source or destination image exceeds 33554431 (0x1FFFFFF).
ippStsDataTypeErr
Indicates an error if
dataType
has an illegal value.
