Parameters
pSrc
Pointer to the ROI in the pixel-order source image. Array of pointers to the ROI in each plane of the planar source image.
srcStep
Distance in bytes between starts of consecutive lines in the source image. Array of distance values for the source image planes.
pDst
Pointer to the destination image ROI.
dstStep
Distance in bytes between starts of consecutive lines in the destination image.
roiSize
Size of the ROI in pixels, its width should be multiple of 2.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts
4:2:2
YCbCr
source image
pSrc
to the 4:2:2
YCrCb
two-channel image
pDst
that has the following sequence of samples:
Y0
,
Cr0
,
Y1
,
Cb0
,
Y2
,
Cr1
,
Y3
,
Cb1
, ... (see Table
“Pixel-Order Image Formats”
). The source image can be either two-channel or three-plane (see Table
“Pixel-Order Image Formats”
and Table
“Planar Image Formats”
).
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error.
ippStsNullPtrErr
Indicates an error condition if any of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error condition if
roiSize.width
is less than 2.

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.
