Parameters

pSrc

Array of pointers to the ROI in each plane of the source image.

srcStep

Array of distances in bytes between starts of consecutive lines in each 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 converts the 4:2:0YCrCb three-plane image pSrc to the 4:2:2YCbCr three-plane or two-channel image pDst (see Table “Pixel-Order Image Formats” and Table “Planar Image Formats”).

This function operates with ROI (see Regions of Interest in Intel IPP).

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.
