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 ROI.
dstStep
Distance in bytes between starts of consecutive lines in the destination image.
roiSize
Size of the source and destination image ROI.
border
Type of border; the possible value is
ippBorderRepl
, which means that a replicated border is used.
pState
Pointer to the morphology state structure.
Description
This function operates with ROI (see Regions of Interest in Intel IPP).
This function performs gray-kernel dilation of a rectangular ROI area inside a one-channel 2D image using a specified in the gray-kernel morphology state structure
pState
mask and the anchor cell. This structure must be initialized by
MorphGrayInit
beforehand.
The structure can be used to process images with ROI that does not exceed the specified maximum width and height
roiSize
.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or a warning.
ippStsNullPtrErr
Indicates an error condition if one of the specified pointers is
NULL
.
ippStsSizeErr
Indicates an error condition if
roiSize
has a field with a zero or negative value, or if one of ROI width or height is greater than corresponding size of ROI passed to the initialization functions.
ippStsStepErr
Indicates an error condition if
srcStep
or
dstStep
is less than
roiSize.width
*
<pixelSize>
.
ippStsNotEvenStepErr
Indicates an error condition if one of the step values is not divisible by 4 for floating-point images.
ippStsBorderErr
Indicates an error condition if
border
has an illegal value.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
