ResizeYUV422GetSrcOffset

Computes the offset of the source image for the YUY2 resize transform by tile processing.

Syntax

IppStatus ippiResizeYUV422GetSrcOffset(
const
IppiResizeYUV422Spec*
pSpec
, IppiPoint
dstOffset
, IppiPoint*
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
ippiResizeYUV422GetSrcOffset
function, you need to initialize the
pSpec
parameter by calling one of the following functions:
ippiResizeYUV422NearestInit
and
ippiResizeYUV422LinearInit
.
Return Values
ippStsNoErr
Indicates no error.
ippStsNullPtrErr
Indicates an error if one of the specified pointers is
NULL
.
ippStsMisalignedOffsetErr
Indicates an error if the
x
field of the
dstOffset
parameter is odd.
ippStsOutOfRangeErr
Indicates an error if the destination image offset point is outside the destination image origin.
ippStsContextMatchErr
Indicates an error if pointer to the spec structure is invalid.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
