Parameters
pSrcY |
Pointer to the ROI in the luminance plane of the source image. |
srcYStep |
Distance in bytes between starts of consecutive lines in the luminance plane of the source image. |
pSrcCbCr |
Pointer to the ROI in the interleaved chrominance plane of the source image. |
srcCbCrStep |
Distance in bytes between starts of consecutive lines in the interleaved chrominance plane of the source image. |
pDst |
Array of pointers to the ROI in each plane of the destination image. |
dstStep |
Array of distances in bytes between starts of consecutive lines in each plane of the destination image. |
roiSize |
Size of the ROI in pixels, its width should be multiple of 4, its height should be multiple of 2. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the 4:1:1 two-plane source image pSrc to the 4:2:0 three-plane image pDst with a different order of components. The first plane of the source image pSrcY contains luminance samples Y0, Y1, Y2, ..., the second plane pSrcCbCr contains interleaved chrominance samples Cb0, Cr0, Cb1, Cr1, ... .The destination image has the following order of pointers: Y-plane, Cr-plane, Cb-plane (see 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 4 or roiSize.height is less than 2. |
