WPF Textblock translation based on reference point

Question

Please check the attached image. I made the textblock origin to it's center by RenderTransformOrigin="0.5,0.5". Now I would like to move the textblock based on the reference point. May be (0,0 ) or (10,10) or ...... These are absolute points. For example, in case of (0,0) the textblock should move to absolute (0,0) based on its reference point. I know how to move relatively by TranslateTransform, but this case I need absolute transform.

Maybe you need this

void MoveToPoint(UIElement sender, Point point)
{
    Canvas.SetLeft(sender, point.X - sender.RenderTransformOrigin.X * sender.ActualWidth);
    Canvas.SetTop(sender, point.Y - sender.RenderTransformOrigin.Y * sender.ActualHeight);
}

to Xaml (patern MVVM): you need write converter and for properties Canvas.Left and Canvas.Top use Binding. It's more code than previously.

Example Converter (example 6) http://www.codeproject.com/Articles/29054/WPF-Data-Binding-Part

In converter need send 2 parameters sender.RenderTransformOrigin.X and ActualWidth.
