public PDAppearanceStream(COSStream s) 
{
        stream = s;
}

Constructor.

Parameters:

s - The cos stream for this appearance.

 public PDRectangle getBoundingBox() 
{
        PDRectangle box = null;
        COSArray bbox = (COSArray)stream.getDictionaryObject( COSName.getPDFName( "BBox" ) );
        if( bbox != null )
        {
            box = new PDRectangle( bbox );
        }
        return box;
}

Get the bounding box for this appearance. This may return null in which case the Rectangle from the annotation should be used.

 public COSBase getCOSObject() 
{
        return stream;
}

{@inheritDoc}

 public PDResources getResources() 
{
        PDResources retval = null;
        COSDictionary dict = (COSDictionary)stream.getDictionaryObject( COSName.RESOURCES );
        if( dict != null )
        {
            retval = new PDResources( dict );
        }
        return retval;
}

This will get the resources for this appearance stream.

 public COSStream getStream() 
{
        return stream;
}

This will return the underlying stream.

 public  void setBoundingBox(PDRectangle rectangle) 
{
        COSArray array = null;
        if( rectangle != null )
        {
            array = rectangle.getCOSArray();
        }
        stream.setItem( COSName.getPDFName( "BBox" ), array );
}

This will set the bounding box for this appearance stream.

 public  void setResources(PDResources resources) 
{
        COSDictionary dict = null;
        if( resources != null )
        {
            dict = resources.getCOSDictionary();
        }
        stream.setItem( COSName.RESOURCES, dict );
}

This will set the new resources.
