public PDAnnotationLink() 
{
        super();
        getDictionary().setItem( COSName.SUBTYPE, COSName.getPDFName( SUB_TYPE ) );
}

Constructor.

 public PDAnnotationLink(COSDictionary field) 
{
        super( field );
}

Creates a Link annotation from a COSDictionary, expected to be a correct object definition.

Parameters:

field - the PDF objet to represent as a field.

 public PDAction getAction() throws IOException 
{
        COSDictionary action = (COSDictionary)
            this.getDictionary().getDictionaryObject( COSName.A );
        return PDActionFactory.createAction( action );
}

Get the action to be performed when this annotation is to be activated.

 public PDBorderStyleDictionary getBorderStyle() 
{
        COSDictionary bs = (COSDictionary) this.getDictionary().getItem(
                COSName.getPDFName( "BS" ) );
        if (bs != null)
        {
            return new PDBorderStyleDictionary( bs );
        }
        else
        {
            return null;
        }
}

This will retrieve the border style dictionary, specifying the width and dash pattern used in drawing the line.

 public PDDestination getDestination() throws IOException 
{
        COSBase base = getDictionary().getDictionaryObject( COSName.DEST );
        PDDestination retval = PDDestination.create( base );
        return retval;
}

Get the destination to be displayed when the annotation is activated. Either this or the A should be set but not both.

 public String getHighlightMode() 
{
        return getDictionary().getNameAsString( COSName.H, HIGHLIGHT_MODE_INVERT );
}

Set the highlight mode for when the mouse is depressed. See the HIGHLIGHT_MODE_XXX constants.

 public PDActionURI getPreviousURI() 
{
        COSDictionary pa = (COSDictionary) getDictionary().getDictionaryObject("PA");
        if ( pa != null )
        {
            return new PDActionURI( pa );
        }
        else
        {
            return null;
        }
}

This will set the previous URI action, in case it's needed.

 public float[] getQuadPoints() 
{
        COSArray quadPoints = (COSArray) getDictionary().getDictionaryObject( "QuadPoints" );
        if (quadPoints != null)
        {
            return quadPoints.toFloatArray();
        }
        else
        {
            return null; // Should never happen as this is a required item
        }
}

This will retrieve the set of quadpoints which encompass the areas of this annotation which will activate.

 public  void setAction(PDAction action) 
{
        this.getDictionary().setItem( COSName.A, action );
}

Set the annotation action. As of PDF 1.6 this is only used for Widget Annotations

 public  void setBorderStyle(PDBorderStyleDictionary bs) 
{
        this.getDictionary().setItem( "BS", bs);
}

This will set the border style dictionary, specifying the width and dash pattern used in drawing the line.

 public  void setDestination(PDDestination dest) 
{
        getDictionary().setItem( COSName.DEST, dest );
}

The new destination value.

 public  void setHighlightMode(String mode) 
{
        getDictionary().setName( COSName.H, mode );
}

Set the highlight mode. See the HIGHLIGHT_MODE_XXX constants.

 public  void setPreviousURI(PDActionURI pa) 
{
        getDictionary().setItem( "PA", pa );
}

This will set the previous URI action, in case it needs to be retrieved at later date.

 public  void setQuadPoints(float[] quadPoints) 
{
        COSArray newQuadPoints = new COSArray();
        newQuadPoints.setFloatArray( quadPoints );
        getDictionary().setItem( "QuadPoints", newQuadPoints );
}

This will set the set of quadpoints which encompass the areas of this annotation which will activate.
