Parameters
pSrc
Pointer to the source image ROI.
srcStep
Distance in bytes between starts of consecutive lines in the source image.
pDst
Pointer to the destination image.
dstStep
Distance in bytes between starts of consecutive lines in destination image.
srcDstStep
Distance in bytes between starts of consecutive lines in the source and the destination image.
srcRoiSize
Size of the source ROI in pixels.
dstRoiSize
Size of the destination ROI in pixels.
topBorderHeight
Height of the top border in pixels.
leftBorderWidth
Width of the left border in pixels.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function copies the source image
pSrc
to the destination image
pDst
and fills pixels ("border") outside the copied area in the destination image with the values of the source image pixels according to the scheme illustrated in Figure Creating a Replicated Border. Squares marked in red correspond to pixels copied from the source image, that is, the source image ROI.
Note that the in-place function flavor actually adds border pixels to the source image ROI, thus a destination image ROI is larger than the initial image.
The parameters
topBorderHeight
and
leftBorderWidth
specify the position of the first pixel of the source ROI in the destination image ROI.
Creating a Replicated Border
The height (width) of the destination ROI cannot be less than the sum of the height (width) of source ROI and the
topBorderHeight
(
leftBorderWidth
) parameter.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error when any of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error condition if
srcRoiSize
or
dstRoiSize
has a field with a zero or negative value, or
topBorderHeight
or
leftBorderWidth
is less than zero, or
dstRoiSize.width
<
srcRoiSize.width
+
leftBorderWidth
, or
dstRoiSize.height
<
srcRoiSize.height
+
topBorderHeight
.
ippStsStepErr
Indicates an error condition if
srcStep
or
dstStep
has a zero or negative value.

Example

The code example below shows how to use the
ippiCopyReplicateBorder_8u_C1R
function.
Ipp8u src[8*4] = {5, 4, 3, 4, 5, 8, 8, 8, 3, 2, 1, 2, 3, 8, 8, 8, 3, 2, 1, 2, 3, 8, 8, 8, 5, 4, 3, 4, 5, 8, 8, 8}; Ipp8u dst[9*8]; IppiSize srcRoi = { 5, 4 }; IppiSize dstRoi = { 9, 8 }; int topborderHeight = 2; int leftborderWidth = 2; ippiCopyReplicateBorder_8u_C1R(src, 8, srcRoi, dst, 9, dstRoi, topBorderHeight, leftBorderWidth);
Results source image: 5 4 3 4 5 8 8 8 3 2 1 2 3 8 8 8 3 2 1 2 3 8 8 8 5 4 3 4 5 8 8 8 destination image: 5 5 5 4 3 4 5 5 5 5 5 5 4 3 4 5 5 5 5 5 5 4 3 4 5 5 5 3 3 3 2 1 2 3 3 3 3 3 3 2 1 2 3 3 3 5 5 5 4 3 4 5 5 5 5 5 5 4 3 4 5 5 5 5 5 5 4 3 4 5 5 5
