Parameters

pSpec

Pointer to the specification structure.

roiSize

Maximal size of the image ROI (in pixels) that can be processed using the allocated structure.

pMask

Pointer to the mask.

maskSize

Size of the mask in pixels.

pBuffer

Pointer to the external buffer for advanced morphological operations.

Description

This function operates with ROI.

This function initializes the specification structure pSpec in the external buffer. This structure is used by the MorphOpenBorder and MorphCloseBorder functions that perform open and close morphological operations.

All advanced morphological operations are performed on the source image pixels corresponding to non-zero values of the structuring element (mask) pMask.

Note

This function required that the image ROI does not exceed the maximum width and height roiSize specified by the initialization functions.

For an example on how to use this function, see the code example provided with the MorphCloseBorder function description.

Return Values

ippStsNoErr

Indicates no error.

ippStsNullPtrErr

Indicates an error when one of the specified pointers is NULL.

ippStsSizeErr

Indicates an error when maskSize has a field with a zero or negative value, or if roiWidth is less than 1.

ippStsAnchorErr

Indicates an error when anchor is outside the mask.
