• 1. Constructor Shape shape; GrowCurve curveOnShape = new GrowCurve(shape);

• 2. growing methods. Choose one of following:

  Vector grow(Vector curve, float distance) 
  BitSetMask grow(BitSetMask mask, float distance) 
  void growCurve(BitSetMask mask, float distance) 
  

Note: description of arguments and returning values are the same as one defined in the InteriorClassifier Example.

ShrinkCurve Example

• 1. Constructor Shape shape; ShrinkCurve curveOnShape = new ShrinkCurve(shape);

• 2. shrink methods. Choose one of following:

  Vector ShrinkCurve(Vector curve, float distance) 
  BitSetMask ShrinkCurve(BitSetMask mask, float distance) 
  void ShrinkCurve(BitSetMask mask, float distance) 
  

Note: description of arguments and returning values are the same as one defined in the InteriorClassifier Example.

• 1. Use Vector getInterior(Vector polygon, boolean isBoundaryInclusive).

Shape shape = null;
Vector polygon = null;
int[] boundary = {41, 35, 29, 23, 18, 13, 19, 14, 20, 25, 31, 37, 42, 36}; 

InteriorClassifier polygonOnShape = new InteriorClassifier(shape);
Vector interior = polygonOnShape.getInterior(_polygon, true);

• 2. Use BitSetMask getInterior(BitSetMask contour, boolean isBoundaryInclusive)

Shape shape = null;
int[] boundary = {41, 35, 29, 23, 18, 13, 19, 14, 20, 25, 31, 37, 42, 36}; 

InteriorClassifier polygonOnShape = new InteriorClassifier(_shape);
int size = _shape.getVertices().size();
!BitSetMask polygon = new BitSetMask(size);
        
for(int index=0; index<_boundary.length; index++){
           
   polygon.set(_boundary[index]);   
}
        
!BitSetMask mask  = polygonOnShape.getInterior(polygon, true);

• 3. Use void getInteriorMask(BitSetMask contour, boolean isBoundaryInclusive)
