Hi,

with the latest version of the library 3.4.1 we're experiencing the following issue:

when we create a Freeform node by specifying a convex hull and then we call the updatefrompoints in the constructor, the height and the width of the node is no longer set (NaN). So, when the node is added to the diagram, it crashes. Even trying to specify the bounds by manually set valid coordinates leaves the Width and the Height at NaN.

With the previous version of the library the same code was working, do currently we had to drop the latest version.

Can you provide a fix?

Points = new StylusPointCollection(hullPoints);
this.UpdateFromPoints();
 

S.

Actually there's one change where we added support for color attributes for you a bit after the 3.4 release - have you ever tried the build from http://mindfusion.eu/Forum/YaBB.pl?num=1457942173/2#2 ?

Hi,

if we try to use the latest version 3.4.1, we deterministically obtain the following exception.
If we revert back to the previous we've no problems.

This is the constructor of our derived FreeformNode:

      public ClusterNode(string id, Point[] hullPoints, Cluster data, List<ClusterCompanyNode> nodes)
        {
            EnabledHandles = AdjustmentHandles.None;
            Obstacle = false;
            IsEnabled = false;
            Focusable = false;
            HandlesStyle = MindFusion.Diagramming.Wpf.HandlesStyle.Invisible;

            Points = new StylusPointCollection(hullPoints);
            this.UpdateFromPoints();

            ZIndex = 0;
            Closed = true;

            Stroke = Brushes.Transparent;
            StrokeThickness = 0f;
            Id = CLUST_NODE_ID_PREFIX + id;
            IncludedNodes = nodes;


            UpdateStyles(data);

            (this as IHighlightable).Highlight(false, 95, false);
        }
 

Another relative little problem in the 3.4.0 version, was that the stroke of the node, when set, was never taken into account, but always rendered in black

Remove the "StrokeThickness = 0f" assignment and it should work.
