Generating image file ?

[andy C]

You need the Acme graphics library.  There are two ways to do it, either generate the picture and stream it out as type "image/gif" or create a file on the fly and return an img tag to it.    The Library is available at: http://www.acme.com/   Try this just to return the image.  However I think that generating a file is more efficient.   void DisplayGraph(HttpServletResponse res,) throws IOException{     Frame frame = null;     Graphics g = null;  int Scale=1;  System.out.println("Entering Display");  ServletOutputStream out = res.getOutputStream();  // binary output!      try{        frame = new Frame();         frame.addNotify();    Image image = frame.createImage(400, 60);         g = image.getGraphics();        g.setFont(new Font("Serif", Font.PLAIN, 12));         g.setColor(Color.black);         g.fillRect(0,0,400,60);         g.setColor(Color.white);         g.drawString("Some text Say ",10, 15}    System.out.println("Setting Content");             res.setContentType("image/gif");               GifEncoder encoder = new GifEncoder(image, out);     encoder.encode();      }      finally {  System.out.println("Cleaning up");         // Clean up resources         if (g != null) g.dispose();         if (frame != null) frame.removeNotify();  System.out.println("Finished all drawing");      }      } ----- Original Message ----- From: Boon Huat To: [EMAIL PROTECTED] Sent: Friday, February 25, 2000 12:22 AM Subject: Generating image file ? Hi all,   Does anybody know how to generate a simple image file(eg a graph or chart which is dynamic) from a servlet and output this to the client.     Thanks in advance.....   Regards Boon Huat
