Parameters
pSrc |
Array of pointers to the ROI in each plane for a three-plane source image. |
srcStep |
Array of distances in bytes between starts of consecutive lines in each plane for a three-plane source image. |
pSrcY |
Pointer to the ROI in the luminance plane for a two-plane source image. |
srcYStep |
Distance in bytes between starts of consecutive lines in the luminance plane of a source image. |
pSrcCbCr |
Pointer to the ROI in the interleaved chrominance plane for a two-plane source image. |

pDst |
Array of pointers to the ROI in each plane for a three-plane destination image. |
dstStep |
Array of distances in bytes between starts of consecutive lines in each plane for a three-plane destination image. |
pDstY |
Pointer to the ROI in the luminance plane for a two-plane destination image. |
dstYStep |
Distance in bytes between starts of consecutive lines in the luminance plane of a destination image. |
pDstCbCr |
Pointer to the ROI in the interleaved chrominance plane for a two-plane destination image. |
dstCbCrStep |
Distance in bytes between starts of consecutive lines in the chrominance plane of a destination image. |

Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the 4:1:1 planar source image pSrc (see Table “Planar Image Formats”) to the 4:2:0 planar image pDst. Both source and destination images can be three- or two-plane. Three-plane images has the following order of pointers: Y-plane, Cb-plane, Cr-plane (see Table “Planar Image Formats”). Two-plane images contain luminance samples Y0, Y1, Y2, .. in the first plane, and interleaved chrominance samples Cb0, Cr0, Cb1, Cr1, ... in the second plane.
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 4 or roiSize.height is less than 2. |
