Extends the input region so that it contains also all the pixels previously lying in its holes.
|inConnectivity||RegionConnectivity||Type of connectivity used for the region foreground|

|inMaxHoleArea||Integer*||0 -||Maximal area of a hole to be filled|
The operation extends a region to contain all pixels inside any of the region holes. 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.
