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, its width should be multiple of 4.

Description

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

This functionconverts 4:1:1 planar source image pSrc to the 4:2:2 image pDst. 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 either three-plane (see Table “Planar Image Formats”) or two-channel image (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.
