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. |
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.
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. |
