Re: Dynamic GIF

[Martin Peter]

Thanks for the reply.

I am am however have a slight problem with it.

I assume the Frame should be displayed on the HTML page that is produced.

I have tried this and I get nothing, just a blank page.

As a fist step I tried to get a frame with a label...

Frame f = new Frame();
f.addNotify();
Label l = new Label("Hello World...");
f.add(l);

I am picking this up wrong or is there something I am missing ?.

Thanks
Peter.

Hi Peter. If you want to create GIFs, use ACME labs excellent free
gifencoder(http://www.acme.com/), and then do something like this:


Frame frame = null;
Graphics g = null;
FileOutputStream fileOut = null;

try {
     //create an unshown frame
     frame = new Frame();
     frame.addNotify();

     //get a graphics region, using the frame
     Image image = frame.createImage(WIDTH, HEIGHT);
     g = image.getGraphics();

     //manipulate the image
     g.drawString("Hello world", 0, 0);

     //get an ouputstream to a file
     fileOut = new FileOutputStream("test.gif");
     GifEncoder encoder = new GifEncoder(image, fileOut);
     encoder.encode();
} catch (Exception e) {
     ;
} finally {
     //clean up
     if (g != null) g.dispose();
     if (frame != null) frame.removeNotify();
     if (fileOut != null) {
          try { fileOut.close(); }
          catch (IOException ioe) { ; }
          }
}

hope this works for you.
