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 |
Pointer to the destination image ROI. |
dstStep |
Distance in bytes between starts of consecutive lines in the 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 planar 4:2:0 two-plane source image to the pixel-order 4:2:2 two-channel image. 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 pDst has the following sequence of samples: Cb0, Y0, Cr0, Y1, Cb1, Y2, Cr1, Y3, Cb2, ...
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. |
