System.Drawing.Bitmap b2= new System.Drawing.Bitmap(@"C:\WINNT\CIBAH.BMP");
            System.Drawing.Graphics g= System.Drawing.Graphics.FromImage(b);
g.Clear(Color.White);
//Graphics g= Button1.CreateGraphics();
Font drawFont = new Font("Arial", 16);
float x = 150.0F;
float y =  50.0F;
SolidBrush drawBrush = new SolidBrush(Color.Black);
            g.DrawImage(b2,0,0,100,100);
g.DrawString(drawString,drawFont,drawBrush,x,y);
b.Save(Response.OutputStream,System.Drawing.Imaging.ImageFormat.Jpeg);//
b.Dispose();
b2.Dispose();
g.Dispose(); }
