Parameters
- pSpec
- Pointer to the spec structure for the resize filter.
- dstRoiOffset
- Offset of the tiled destination image ROI.
- dstRoiSize
- Size of the tiled destination image ROI.
- srcRoiOffset
- Offset of the source image ROI.
- srcRoiSize
- Pointer to the size of the source image ROI.
Description
This function computes the ROI of the processed source image
using the processed ROI of the destination image for the corresponding resize
transform by tile processing. The
pSpec
parameter defines the resize algorithm parameters. Prior to
using the ippiResizeYUV422GetSrcRoi
function, you need to initialize the
pSpec
parameter by
calling one of the following functions: ippiResizeYUV422NearestInit
or ippiResizeYUV422LinearInit
.If the destination ROI size exceeds
the image origin, the source ROI will be obtained for an intersection of the
destination ROI and image origin.
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 specification structure is invalid.
- ippStsOutOfRangeErr
- Indicates an error if the destination image offset point is outside the destination image origin.
- ippStsMisalignedOffsetErr
- Indicates an error if x-value of the parameterdstRoiOffsetis odd.
- ippStsSizeErr
- Indicates an error in the following cases:
- If the height of the destination ROI is zero or negative.
- If the width of the destination ROI is less than 2.
- ippStsSizeWrn
- Indicates a warning in the following cases:
- If the width of the destination ROI is odd.
- If the destination ROI exceeds the destination image origin.
