How to share image on social Media in WP8.1 Rt?

I have created app in wp8.1 rt. When button is clicked i need to take screen shot of page and share it on social media(like facebook,twiter ,...). Upto now what i have done is -

DataTransferManager dtManager = DataTransferManager.GetForCurrentView();
   dtManager.DataRequested += dtManager_DataRequested;


private async void dtManager_DataRequested(DataTransferManager sender, DataRequestedEventArgs e)
    {

        e.Request.Data.Properties.Title = "here is title";
        e.Request.Data.Properties.Description = "H..........";
        e.Request.Data.SetWebLink(new Uri("http://......."));
       //here i need to add image also
    }

private void share_Click(object sender, RoutedEventArgs e)
    {

        Windows.ApplicationModel.DataTransfer.DataTransferManager.ShowShareUI();
    }

Upto here its working ,i am able to share title, discription,.... but unable to share image that capture programatically For capturing image what i have done is below:

 private async Task<RenderTargetBitmap> CreateBitmapFromElement(FrameworkElement uielement)
    {
        try
        {
            var renderTargetBitmap = new RenderTargetBitmap();
            await renderTargetBitmap.RenderAsync(uielement);

            return renderTargetBitmap;
        }
        catch (Exception ex)
        {
            System.Diagnostics.Debug.WriteLine(ex);
        }

        return null;
    }

img.source= await CreateBitmapFromElement(rootcontent); //here rootcontent is my grid name that i need to capture.

Here i am able to get imge also. But unable to share this captured image. I read some blogs but still unable to solve it. I think i need to convert it to BitmapImage. How can i do that?? Or is there another best way of handling this problem.

what I need is when share button is clicked ,i need to capture screenshot and share it on social media (like facebook).

You can use e.Request.Data.SetBitmap to transfer a screen shot. But the parameter type of this method is RandomAccessStreamReference, so you need to convert the RenderTargetBitmap to RandomAccessStreamReference.

The essential idea is: Get the pixels and write the pixels to a InMemoryRandomAccessStream.

You can find the code reference from article How to use the RenderTargetBitmap in Windows 8.1.
