AVL.RegionContours(AvlNet.Region, AvlNet.RegionContourMode, AvlNet.RegionConnectivity, AvlNet.Path[])

Namespace:AvlNet
Assembly:AVL.NET.dll

Syntax


public static void RegionContours(
	AvlNet.Region inRegion,
	AvlNet.RegionContourMode inContourMode,
	AvlNet.RegionConnectivity inRegionConnectivity,
	out AvlNet.Path[] outContours
)

Parameters

inRegion
Type: AvlNet.Region
inContourMode
Type: AvlNet.RegionContourMode
inRegionConnectivity
Type: AvlNet.RegionConnectivity
outContours
Type: AvlNet.Path

Description

The operation forms an array of paths that, depending on the value of the inContourMode parameter:

  • Pass through the centers of boundary pixels of the region, if inContourMode is set to PixelCenters
  • Run along the edges of boundary pixels of the region, if inContourMode is set to PixelEdges

To compute the approximation of the region perimeter length, one can use RegionPerimeterLength filter.

Examples

The computed outContours array drawn onto an empty image.
