Removes interior pixels from a region.
const avl::Region& inRegion,
||Type of connectivity used for the region foreground
The operation removes all internal pixels from the region (thus leaving only the boundary pixels). The definition of internal pixel depends on the inConnectivity value:
- If inConnectivity is set to Four directions, internal pixels are those having neighbours in all four major directions (up, down, left, right) also contained in the region
- If inConnectivity is set to Eight directions, internal pixels are those having neighbours in all eight directions (four major + four diagonal) also contained in the region
RegionBoundaries run on a sample region.
- RegionContours – Computes an array of closed paths corresponding to the contours of the input region.
