AutoFringer

public AutoFringer(FringeConfiguration fringeconf,
                   ImageManager imgr,
                   TileManager tmgr)

Constructs an instance that will fringe according to the rules in the supplied fringe configuration.

Method Detail

getFringeConf

public FringeConfiguration getFringeConf()

Returns the fringe configuration used by this fringer.

getFringeTile

public BaseTile getFringeTile(MisoSceneModel scene,
                              int col,
                              int row,
