Parameters
- srcSize
- Size of the source image in pixels.
- dstSize
- Size of the destination image in pixels.
- interpolation
- Interpolation method. Supported values areippNearestandippLinear.
- 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 isNULL.
- 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 ifinterpolationhas 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.
