Parameters
- pSrc
- Pointer to the source image ROI.
- srcStep
- Distance, in bytes, between the starting points of consecutive lines in the source image.
- pDst
- Pointer to the destination image ROI.
- dstStep
- Distance, in bytes, between the starting points of consecutive lines in the destination image.
- roiSize
- Size of the source and destination ROI, in pixels.
- borderType
- Type of the border; supported values:
- ippBorderDefault
- The border is set toippBorderConstwithborderValue=MIN_VALUE, whereMIN_VALUE=IPP_MIN_8U/16U/16S/32F/1U
- ippBorderRepl
- Border is replicated from the edge pixels.
- ippBorderMirror
- Border pixels are mirrored from the source image boundary pixels.
- ippBorderConst
- Values of all border pixels are set to a constant.
- ippBorderInMem
- Border is obtained from the source image pixels in memory.
Mixed borders are also supported. They can be obtained by the bitwise operationORbetween any of theippBorderRepl,ippBorderConst, orippBorderMirrorvalues and theippBorderInMemTop,ippBorderInMemBottom,ippBorderInMemLeft,ippBorderInMemRightvalues. - borderValue
- Pointer to the vector of values for the constant border type.
- srcBitOffset
- Offset in the first byte of the source image row.
- dstBitOffset
- Offset in the first byte of the destination image row.
- pMorphSpec
- Pointer to the morphology specification structure.
- pBuffer
- Pointer to the external work buffer.
Description
This function operates with ROI (see Regions of Interest in Intel
IPP).
This function performs dilation of a rectangular ROI area inside a
one-, three-, or four-channel 2D image using a specified mask
pMask
of size maskSize
and alignment
anchor
.Source and destination images can be of different sizes, but the
ROI size is the same for both images. The output pixel is set to the maximum of the
corresponding input pixel and its neighboring pixels that are picked out by the
nonzero mask values. In the four-channel image the alpha channel is not
processed.
Return Values
- ippStsNoErr
- Indicates no error. Any other value indicates an error or a warning.
- ippStsNullPtrErr
- Indicates an error condition ifpSrcorpDstisNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas a field with a zero or negative value.
- ippStsStepErr
- Indicates an error condition ifsrcStepordstStephas a zero or negative value.
- ippStsNotEvenStepErr
- Indicates an error condition ifsrcStepordstStephas a not pixel multiple value.
- ippStsBadArgErr
- Indicates an error condition ifborderTypehas an incorrect value.
