public PDPageFitWidthDestination() 
{
        super();
        array.growToSize(3);
        array.setName( 1, TYPE );
}

Default constructor.

 public PDPageFitWidthDestination(COSArray arr) 
{
        super( arr );
}

Constructor from an existing destination array.

Parameters:

arr - The destination array.

 public boolean fitBoundingBox() 
{
        return TYPE_BOUNDED.equals( array.getName( 1 ) );
}

A flag indicating if this page destination should just fit bounding box of the PDF.

 public int getTop() 
{
        return array.getInt( 2 );
}

Get the top y coordinate. A return value of -1 implies that the current y-coordinate will be used.

 public  void setFitBoundingBox(boolean fitBoundingBox) 
{
        array.growToSize( 2 );
        if( fitBoundingBox )
        {
            array.setName( 1, TYPE_BOUNDED );
        }
        else
        {
            array.setName( 1, TYPE );
        }
}

Set if this page destination should just fit the bounding box. The default is false.

 public  void setTop(int y) 
{
        array.growToSize( 3 );
        if( y == -1 )
        {
            array.set( 2, (COSBase)null );
        }
        else
        {
            array.setInt( 2, y );
        }
}

Set the top y-coordinate, a value of -1 implies that the current y-coordinate will be used.
