ResizeYUV420GetSrcOffset
Computes the offset of the source image for the NV12 resize transform by tile processing.
Syntax
IppStatus ippiResizeYUV420GetSrcOffset(const IppiResizeYUV420Spec* pSpec, IppiPoint dstOffset, IppiPoint* srcOffset);
Include Files
ippi.h
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. |
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 is NULL. |
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 the dstOffset parameter is odd. |
