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 isippBorderRepl, 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 erosion 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 isNULL.
- ippStsSizeErr
- Indicates an error condition ifroiSizehas 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 ifsrcStepordstStepis less thanroiSize.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 ifborderhas an illegal value.
