    Parameters:
    
    ulx - The uper-left x-coordinate
    
    uly - The uper-left y-coordinate
    
    w - Width of the code-block
    
    h - Height of the code-block
    
    nl - The number of layers

```
public void addNTP(int l,
                   int newtp)
```
    Adds the number of new truncation for specified layer.
    
    Parameters:
    
    l - layer index
    
    newtp - Number of new truncation points
  - toString
