Parameters
srcSize
Size of the source image in pixels.
dstSize
Size of the destination image in pixels.
interpolation
Interpolation method. Supported values are
ippNearest
and
ippLinear
.
antialiasing
Antialiasing method.
pSpecSize
Pointer to the size in bytes of the spec structure.
pInitBufSize
Pointer to the size in bytes of the temporal buffer.
Description
This function computes sizes of the spec structure and the external buffer that are required for one of the following functions depending on the interpolation method parameter: ResizeYUV422NearestInit and ResizeYUV422LinearInit .
The filter sizes of the Nearest Neighbor and Linear interpolation algorithms are 2x1 and 4x2 respectively.
Antialiasing is currently not supported. The value for the
antialiasing
parameter must be equal to zero.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error.
ippStsNullPtrErr
Indicates an error condition if one of the specified pointers is
NULL
.
ippStsNoOperation
Indicates a warning if width or height of the image is equal to zero.
ippStsSizeErr
Indicates an error in the following cases:
  • if the source image size is less than the filter size for the chosen interpolation method,
  • if one of the calculated sizes exceeds maximum 32 bit signed integer positive value (the size of one of the processed images is too large).
ippStsSizeWrn
Indicates a warning if width of the image is odd.
ippStsInterpolationErr
Indicates an error if
interpolation
has an illegal value.
ippStsNoAntialiasing
Indicates a warning if the specified interpolation method does not support antialiasing.
ippStsNotSupportedModeErr
Indicates an error if the requested mode is currently not supported.
