void avl::RegionHoles ( const avl::Region& inRegion, avl::RegionConnectivity::Type inConnectivity, int inMinHoleArea, atl::Optional<int> inMaxHoleArea, atl::Array<avl::Region> & outHoles )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|

inMinHoleArea | int | 0 - ![]() |
1 | Minimal area of a resulting hole |
![]() |
inMaxHoleArea | Optional<int> | 0 - ![]() |
NIL | Maximal area of a resulting hole |
![]() |
outHoles | Array<Region> & |
Description
The operation computes regions representing holes of input region. Holes of a region are those connected areas of pixels not belonging to the region, that do not touch the boundary of the region frame.
Examples
