ResizeYUV422GetSrcRoi
Computes the ROI of the source image for YUV422 resizing by tile processing.
Syntax
IppStatus ippiResizeYUV422GetSrcRoi(const IppiResizeYUV422Spec* pSpec, IppiPoint dstRoiOffset, IppiSize dstRoiSize, IppiPoint* srcRoiOffset, IppiSize* srcRoiSize);

Domain Dependencies
Headers: ippcore.h, ippvm.h, ipps.h
Libraries: ippcore.lib, ippvm.lib, ipps.lib
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 is NULL. |
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 parameter dstRoiOffset is odd. |
ippStsSizeErr |
Indicates an error in the following cases:
|
ippStsSizeWrn |
Indicates a warning in the following cases:
