Parameters
pSrc |
Pointer to the source image ROI. |
srcStep |
Distance in bytes between starts of consecutive lines in the source image. |
pDst |
Array of pointers to the ROI in each plane of the destination image. |
pDstY |
Pointer to the destination image Y plane. |
dstStep |
Array of distances, in bytes, between the starting points of consecutive lines in the destination image planes. |
dstYStep |
Array of distances, in bytes, between the starting points of consecutive lines in the destination image Y plane. |
dstUVStep |
Array of distances, in bytes, between the starting points of consecutive lines in the destination image UV plane. |
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 4:2:2 two-channel image pSrc that has the following sequence of samples: Y0, Cb0, Y1, Cr0, Y2, Cb1, Y3, Cr1, ... to the 4:2:0 three-plane image pDst with the following order of pointers: Y-plane, Cr-plane, Cb-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 any field of the roiSize is less than 2. |
