FIL.CloseRegion
Performs a morphological closing on a region using selected predefined kernel.
| Namespace: | FilNet |

| Assembly: | FIL.NET.dll |
Syntax
C++
C#
public static void CloseRegion ( FilNet.Region inRegion, FilNet.KernelShape inKernel, int inRadiusX, int? inRadiusY, FilNet.Region outRegion )
Parameters
| Name | Type | Range | Default | Description | |
|---|---|---|---|---|---|
 | inRegion | FilNet.Region | Input region. | ||
| inKernel | FilNet.KernelShape | Kernel shape (predefined). | ||
| inRadiusX | int | <0, INF> | 1 | Nearly half of the kernel's width (2*R+1). Default value: 1. |
| inRadiusY | int? | <0, INF> | Nearly half of the kernel's height (2*R+1), or same as inRadiusX. Default value: ftl::NIL. | |
 | outRegion | FilNet.Region | Output region. |
Description
The operation performs a morphological closing, which is a tool used for filling gaps in a region. The operation is a convolution of two basic morphological operations:
- Firstly, the input region is dilated using DilateRegion operation.
- Then, the resulting region is eroded using ErodeRegion operation.
During the dilation gaps that are small enough are actually closed, while further erosion assures that the width of region limbs is preserved.
Both of the component operations are conducted using the same inKernel, inRadiusX and inRadiusY parameters.
Examples
 |
 |
CloseRegion run with inKernel = Ellipse of dimensions inRadiusX = 5, inRadiusY = 5.
