Computes the offset of the source image for the NV12
resize transform by tile processing.

Parameters
- pSpec
- Pointer to the spec structure for the resize filter.
- dstOffset
- Offset of the tiled destination image with respect to the destination image origin.
- srcOffset
- Offset of the source image.
Description
This function computes the offset of the processed source image
ROI using the offset of the processed destination image ROI for the corresponding
resize transform by tile processing. The
pSpec
parameter defines the
resize algorithm parameters. Prior to using the ippiResizeGetSrcOffset
function,
you need to initialize the pSpec
parameter by calling one of the following functions: ippiResizeYUV420LanczosInit
and ippiResizeYUV420SuperInit
.Return Values
- ippStsNoErr
- Indicates no error.
- ippStsNullPtrErr
- Indicates an error if one of the specified pointers isNULL.
- ippStsContextMatchErr
- Indicates an error if pointer to the spec structure is invalid.
- ippStsOutOfRangeErr
- Indicates an error if the destination image offset point is outside the destination image origin.
- ippStsMisalignedOffsetErr
- Indicates an error if one of the fields of thedstOffsetparameter is odd.
