Parameters
pSrc |
Array of pointers to the ROI in each plane of the source image. |
srcStep |
Array of distances in bytes between starts of consecutive lines in each plane of the source image. |
pDstY |
Pointer to the ROI in the luminance plane of a destination image. |
dstYStep |
Distance in bytes between starts of consecutive lines in the luminance plane of the destination image. |
pDstCbCr |
Pointer to the ROI in the interleaved chrominance plane of the destination image. |
dstCbCrStep |
Distance in bytes between starts of consecutive lines in the interleaved chrominance plane of a destination image. |
roiSize |
Size of the source and destination ROI in pixels, height and width should be multiple of 2. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the 4:2:0YCrCb three-plane image pSrc (see Table “Planar Image Formats”) to the 4:2:0 YCbCr two-plane image that contains luminance samples Y0, Y1, Y2, .. in the first plane pDstY, and interleaved chrominance samples Cb0, Cr0, Cb1, Cr1, ... in the second plane pDstCbCr.
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 any field of the roiSize is less than 2. |
