Hello there ! Try this links : http://www.aspsnippets.com/Articles/Create-Add-Watermark-Text-to-Images-Photo-in-ASPNet-using-C-and-VBNet.aspx or might be this works : protected void Upload( object sender, EventArgs e) { string watermarkText = "© ASPSnippets.com" ; //Get the file name. string fileName = Path.GetFileNameWithoutExtension(FileUpload1.PostedFile.FileName) + ".png" ; //Read the File into a Bitmap. using (Bitmap bmp = new Bitmap(FileUpload1.PostedFile.InputStream, false )) { using (Graphics grp = Graphics.FromImage(bmp)) { //Set the Color of the Watermark text. Brush brush = new SolidBrush(Color.FromArgb(99, Color.Black)); //Set the Font and its size. Font font = new System.Drawing.Font( "Arial" , 30, FontStyle.Bold, GraphicsUnit.Pixel); //Determine the size of the Watermark text. SizeF textSize = new SizeF(); textSize = grp.MeasureString(watermarkText, font); //Position the text and draw it on the image. Point position = new Point((bmp.Width / 2), (bmp.Height / 2)); //Rotate and Draw grp.TranslateTransform(position.X / 2, position.Y / 2); grp.RotateTransform(-45); grp.DrawString(watermarkText, font, brush, position.X - (( int )textSize.Width + 10), position.Y - (( int )textSize.Height + 10)); grp.ResetTransform(); using (MemoryStream memoryStream = new MemoryStream()) { //Save the Watermarked image to the MemoryStream. bmp.Save(memoryStream, ImageFormat.Png); memoryStream.Position = 0; //Start file download. Response.Clear(); Response.ContentType = "image/jpg" ; Response.AddHeader( "Content-Disposition" , "attachment; filename=" + fileName); //Write the MemoryStream to the Response. memoryStream.WriteTo(Response.OutputStream); Response.Flush(); Response.Close(); Response.End(); } } } }
