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 isNULL.
- 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 ifdataTypehas an illegal value.
