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. |
srcCbCrStep |
Distance in bytes between starts of consecutive lines in the interleaved chrominance plane of the source image. |
pDst |
Pointer to the ROI in the pixel-order destination image. Array of pointers to the ROI in each plane of the planar destination image. |
dstStep |
Distance in bytes between starts of consecutive lines in the destination image. Array of distance values for the destination image planes. |
roiSize |
Size of the 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 4:2:0 planar source image pSrc to the 4:2:2 image pDst. The source image can be two- or three-plane image (see Table “Planar Image Formats”). The first plane of the two-plane source image pSrcY contains luminance samples Y0, Y1, Y2, ..., the second plane pSrcCbCr contains interleaved chrominance samples Cb0, Cr0, Cb1, Cr1, .... . The destination image pDst can be three-plane or two-channel (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. |
