Question draw text on a picture

Please Login to Remove!

Hi,everyone:

I'm trying to draw something on a picture showed on BB, and I'm confused how to do it. Firstly, I read a picture from card and show it on BB; and now I want to draw text on the picture by a menu "write", could anyone help me ?
Thank you very much!

class picViewer extends UiApplication
{
    public static void main(String[] args)
    {
        //create a new instance of the application
        //and start the application on the event thread
        picViewer theApp = new picViewer();
        theApp.enterEventDispatcher();
    }
    
    public picViewer() 
    {    
        pushScreen(new ViewScreenDemo());
    } 
    
    class ViewScreenDemo extends MainScreen
    {        
        private WriteMenuItem _writeMenuItem;
        private EncodedImage image;
        
        private class WriteMenuItem extends MenuItem 
        {
            private WriteMenuItem() 
            {
                super("write",100000, 5);
            }                  
            public void run() 
            {                
                onWrite();
            }
        } 
        
        public ViewScreenDemo() 
        {
            _writeMenuItem = new WriteMenuItem();
            try 
            {
                FileConnection fconn = (FileConnection)Connector.open("file:///SDCard/BlackBerry/pictures/1.jpg");
                // If no exception is thrown, then the URI is valid, but the file may or may not exist.
                if (fconn.exists()) {
                    InputStream input = fconn.openInputStream();
                    int available = (int)fconn.fileSize();
                    byte[] data = new byte[available];
                    input.read(data, 0, available);
                    EncodedImage image = EncodedImage.createEncodedImage(data,0,data.length);   
                    Bitmap b = image.getBitmap();
                    BitmapField picture = new BitmapField(b);  
                    add(picture);             
                }
                else {
                    add(new LabelField("Picture does not exist"));
                }
                fconn.close();
                }
            catch(Exception ioe)
            { System.out.println("error!");}
        }        
        protected void makeMenu(Menu menu, int instance) 
        {            
            menu.add(_writeMenuItem);
            super.makeMenu(menu, instance);
        } 
        public void onWrite()
        {
            //?????????
        }  
    }
