Hi All,

Below is my code:

C#

System.Drawing.Image bitmap = (System.Drawing.Image)Bitmap.FromFile(Server.MapPath(@"countimage\2.jpg")); // set image
      //draw the image object using a Graphics object
      Graphics graphicsImage = Graphics.FromImage(bitmap);

      //Set the alignment based on the coordinates
      StringFormat stringformat = new StringFormat();
      stringformat.Alignment = StringAlignment.Far;
      stringformat.LineAlignment = StringAlignment.Far;

      StringFormat stringformat2 = new StringFormat();
      stringformat2.Alignment = StringAlignment.Center;
      stringformat2.LineAlignment = StringAlignment.Center;

      //Set the font color/format/size etc..
      Color StringColor = System.Drawing.ColorTranslator.FromHtml("#fff");//customise color adding
      Color StringColor2 = System.Drawing.ColorTranslator.FromHtml("#fff");//customise color adding
      string Str_TextOnImage = Text2.Value;//Your Text On Image
      string Str_TextOnImage1 = Text3.Value;//Your Text On Image


      graphicsImage.DrawString(Str_TextOnImage, new Font("Lighthouse Personal Use", 50,
      FontStyle.Bold), new SolidBrush(StringColor), new Point(200, 250),
      stringformat);

      graphicsImage.DrawString(Str_TextOnImage1, new Font("Lighthouse Personal Use", 50,
    FontStyle.Bold), new SolidBrush(StringColor), new Point(380, 250),
    stringformat);


      bitmap.Save(Server.MapPath("out3/preview2.Jpg"));

Note: Code is running properly on my local host but once i am try to run this code to server it shows an error ,

Check your folders - and stop using relative paths. They have a tendency to fail because the page is moved (or copied) to a different folder on the webserver. Use an absolute path instead:

C#

Server.MapPath(@"~/Images/out1/preview3.Jpg")

If you look, you will find that the folder "out1" probably doesn't exist, or if it does, it doesn't have the required access permissions to let you app write to it.

But...once you "go live" you will have bigger problems: when you get two users trying to do the same thing at the same time, your fixed file names will cause problems because the file will be in use...
