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. |
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, its width should be multiple of 4. |
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function converts the 4:1:1 three-plane image pSrc to the 4:2:2 two-channel or three-plane image pDst with different order of components. The source image has the following order of pointers: Y-plane, Cb-plane, Cr-plane (see Table “Planar Image Formats”). The three-plane destination image has the following order of pointers: Y-plane, Cr-plane, Cb-plane (see Table “Planar Image Formats”), and two-channel destination image has the following sequence of samples: Y0, Cr0, Y1, Cb0, Y2, Cr1, Y3, Cb1, ... (see Table “Pixel-Order 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. |
