[Amol kumar]

actually my project is that i wanna make a software that enable to capture a picture automatically by webcam.
the software should have the capability to start the web cam automatically and capture the object whenever it observe a new object.

//*******THIS IS JUST FOR MONODEVELOP IN LINUX *****///
#First we need to install the Emgu.CV dll (that makes almost #all the magic)
#I made i little example, we need two controls a Gtk.Image #control and a Gdk.PixBuf and also the System.IO; and #System.Drawing ;

//Ok here is the example in Gtk.Window

using System;
using Gtk;
using Emgu.CV;
using Emgu.CV.UI;
using Emgu.CV.Structure;
using System.IO;
using System.Drawing;
using System.Drawing.Imaging;

#i declared global variables
 Gdk.Pixbuf pix;
 Emgu.CV.UI.ImageViewer viewer = new ImageViewer(); //create an image viewer	        
 Emgu.CV.Capture capture = new Capture ();
 System.Drawing.Bitmap bitmap = null;

#When we start the form we are gona use a timer for mono
public MainWindow () : base(Gtk.WindowType.Toplevel)
{
GLib.Timeout.Add (180, new GLib.TimeoutHandler (update_status));	

##This is the event
private  bool update_status ()
{
 Image<Bgr, Byte> Photo=capture.QueryFrame(); 	 	
 viewer.Image = Photo;
 bitmap =  viewer.Image.Bitmap;
 MemoryStream memor = new MemoryStream ();
 bitmap.Save(memor,ImageFormat.Png);
 pix = new Gdk.Pixbuf(memor.ToArray());
 this.image2.Pixbuf = pix;
 memor.Dispose();
 return true;
}
