Enum BorderType

Source 
pub enum BorderType {
    Outer,
    Hole,
}
Expand description

Whether a border of a foreground region borders an enclosing background region or a contained background region.

Variants§

§

Outer

A border between a foreground region and the backround region enclosing it. All points in the border lie within the foreground region.

§

Hole

A border between a foreground region and a background region contained within it. All points in the border lie within the foreground region.
