ResizeGetSrcOffset
Computes the offset of the source image for resizing by tile processing.
Syntax
Single precision
IppStatus ippiResizeGetSrcOffset_<mod>(const IppiResizeSpec_32f* pSpec, IppiPoint dstOffset, IppiPoint* srcOffset);
Supported values for mod:
8u |
16u |
16s |
32f |
Double precision
IppStatus ippiResizeGetSrcOffset_64f(const IppiResizeSpec_64f* pSpec, IppiPoint dstOffset, IppiPoint* srcOffset);
Processing images with platform-aware functions
IppStatus ippiResizeGetSrcOffset_L(const IppiResizeSpec* pSpec, IppiPointL dstOffset, IppiPointL* srcOffset);

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: ippiResizeNearestInit, ippiResizeLinearInit, ippiResizeCubicInit, ippiResizeLanczosInit, or ippiResizeSuperInit.
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. |
