Do you have to merge the images? Can't you just place one image on top of the other?

no..its not like that...i have to merge a perticular icon in a map,suppose in indias map when the administrator is inputting the corresponding geographical measures.(longitude and latitude). first to check whether the given measures are covering which area..after checking that it identifies that area is India.then it finds the inner exact position and merge the icon image there..(For this i am using gif images of background map(image1) and icon(image2).i want to merge image2 on image 1 when ever inserting the measurement in the database...) TRY IT>>>ITS NOT SIMPLE I THINK>>>give me idea about grids also..that can help..

Check the following code In this example Image2 will be added to the Image1, you need to just change the names from Images1.gif and Image2.gif to your image name. Let me know if you have any issues. //Code Starts Here // This is the Original Image that is Image1 System.Drawing.Image bgimage = System.Drawing.Image.FromFile(Server.MapPath("Image1.gif")); Bitmap bmp = new Bitmap(1, 1); Graphics graphic = System.Drawing.Graphics.FromImage(bmp); // measure the image int height = bgimage.Height; int width = bgimage.Width; // recreate our bmp and graphic objects with the new measurements bmp = new Bitmap(width, height); graphic = System.Drawing.Graphics.FromImage(bmp); graphic.DrawImage(bgimage, 0, 0, width, height); graphic.TextRenderingHint = TextRenderingHint.SystemDefault; System.Drawing.Image bgimageNew = System.Drawing.Image.FromFile(Server.MapPath("Image2.jpg")); //You can set x position, y position, width and height of the second image. graphic.DrawImage(bgimageNew,5,5,50,15); // Set the content type and return the image Response.ContentType = "image/JPEG"; bmp.Save(Response.OutputStream, ImageFormat.Jpeg); // dispose of our objects bgimage.Dispose(); graphic.Dispose(); bmp.Dispose(); //Code Ends Here Vicky "Walking on water and developing Software on a specification is easy, if both are frozen..."
