Hi

I have the following scenario where if I add a annotation i.e. a free hand drawing, polygon, rectangle etc. I require a label to be attached to this shape. I did notice that the annotation shapes have a label property which can be made visible however it is positioned in the left corner. My question is, is it possible to set the co-ordinates of this shape to be the rotateCentre co-ordinates of the shape.

I have used the following code to set the label

var point = annRect.rotateCenter;

var label = annRect.get_labels()["AnnObjectName"];
label.set_isVisible(true);
label.set_foreground(lt.Annotations.Core.AnnSolidColorBrush.create("white"));
label.set_background(lt.Annotations.Core.AnnSolidColorBrush.create("red"));
label.set_text("1");
label.set_originalPosition(point);

annRect.labels.AnnObjectName = label;

Any help provided is appriciated

Thank you
Maneka

Hi maneka,

You can achieve this using the following code:

Code:
            AnnLabel label = e.Object.Labels["AnnObjectName"];
            label.IsVisible = true;
            label.Offset = LeadPointD.Create(e.Object.RotateCenter.X - e.Object.Bounds.Left, e.Object.RotateCenter.Y - e.Object.Bounds.Top);
            label.OffsetHeight = false;
            label.Text = e.Object.FriendlyName;
