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 isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSize.widthis less than 4.
