Hi Ahmad,

Were you able to run the Giving the uploaded files unique names example? All you need to do is to override the StoreFile method of the FileSystemContentProvider class of RadEditor and run the watermark code of one of the provided demos:
Watermark your images with this VB.NET code,
Creating a Watermarked Photograph with GDI+ for .NET
and
Add a watermark to an image in VB .NET.

Please note that RadEditor does not offer this feature out-of-the box and we do not support it.

Hi Rumen
There is problem in code , when I upload image , it's add watermark , but it will not upload it and only will keep reviewing it , also when I close the Imagemanager and open it again , the image is still remaining.


Thanks in advanced.

Hi Ahmad,

Thank you for reporting this issue.

To fix it update the code of the StoreFile function as follows:

public override string StoreFile(UploadedFile file, string path, string name, params string[] arguments)

{

    System.Drawing.Image objImage = System.Drawing.Image.FromStream(file.InputStream);//From File

    int height = objImage.Height;//Actual image width

    int width = objImage.Width;//Actual image height

    System.Drawing.Bitmap bitmapimage = new System.Drawing.Bitmap(objImage, width, height);// create bitmap with same size of Actual image

    System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(bitmapimage);

    //Creates a System.Drawing.Color structure from the four ARGB component

    //(alpha, red, green, and blue) values. Although this method allows a 32-bit value

    // to be passed for each component, the value of each component is limited to 8 bits.




     

    //Adding watermark text on image

    //SolidBrush brush = new SolidBrush(Color.FromArgb(113, 255, 255, 255));

    //g.DrawString("WaterMark sample", new Font("Arial", 18, System.Drawing.FontStyle.Bold), brush, 0, 100);

 

    //Adding watermark icon on the image

    Bitmap logo = new Bitmap(this.Context.Server.MapPath("~/images/WaterMark.jpg"));

    g.DrawImage(logo, new Point(70, 70));

 

    string result = VirtualPathUtility.AppendTrailingSlash(path) + name;

    

    bitmapimage.Save(Context.Server.MapPath(result));

    g.Dispose();

    bitmapimage.Dispose();

 

     

    //string result = base.StoreFile(file, path, newFileName, arguments);

    return result;

}

For your convenience I have attached the modified project.
