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. Note, that ippiResizeAntialiasingLinearInit_64f
will initialize the IppiResizeSpec_64f
structure.Before using these functions, 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.
