If I set the StrokeThickness of a diagram link then all horizontal and vertical link segments are drawn incorrectly.   They are not the correct thickness and any portion of their arrowheads that extends beyond about three pixels from the center line of the link appears to be truncated.  Links drawn in other orientations are drawn correctly though.

I am using version 2.5.2.32848 of the diagramming component.

Is this a known problem?  Is there a better way of controlling the thickness of the links?

Thanks,

Stoyo,

Which demo/sample are you referring to? I'll check if it has the same behavior once I know which one it is.

Meanwhile, here is some simple code that shows the problem on my computer...

XAML:

<ScrollViewer Focusable="False" HorizontalScrollBarVisibility="Auto">
<diag:Diagram
Name="diaSchematic"
AllowDrop="True"
Behavior="DrawLinks"
AutoResize="AllDirections"
GridSizeX="80"
GridSizeY="80"
ShowGrid="True"
GridStyle="Lines"
AlignToGrid="True"
/>
</ScrollViewer>

Code:

Private Sub LoadSchematic(ByVal SchematicUID As Guid)
Dim EndA As New ShapeNode()
EndA.Shape = MindFusion.Diagramming.Wpf.Shape.Shapes.Item(1)
diaSchematic.Nodes.Add(EndA)
EndA.Move(0, 0)

'Diagonal
Dim EndB As New ShapeNode()
EndB.Shape = MindFusion.Diagramming.Wpf.Shape.Shapes.Item(2)
diaSchematic.Nodes.Add(EndB)
EndB.Move(200, 200)
diaSchematic.Bounds = diaSchematic.GetContentBounds(False, False)

Dim Link As New DiagramLink( _
diaSchematic _
, EndA _
, EndB _
)
Link.HeadShape = ArrowHeads.Triangle
diaSchematic.Links.Add(Link)
Link.StrokeThickness = 4

'Horizontal
Dim EndC As New ShapeNode()
EndC.Shape = MindFusion.Diagramming.Wpf.Shape.Shapes.Item(3)
diaSchematic.Nodes.Add(EndC)
EndC.Move(0, 200)
diaSchematic.Bounds = diaSchematic.GetContentBounds(False, False)

Link = New DiagramLink( _
diaSchematic _
, EndA _
, EndC _
)
Link.HeadShape = ArrowHeads.Triangle
diaSchematic.Links.Add(Link)
Link.StrokeThickness = 6

'Vertical
Dim EndD As New ShapeNode()
EndD.Shape = MindFusion.Diagramming.Wpf.Shape.Shapes.Item(4)
diaSchematic.Nodes.Add(EndD)
EndD.Move(200, 0)
diaSchematic.Bounds = diaSchematic.GetContentBounds(False, False)

Link = New DiagramLink( _
diaSchematic _
, EndA _
, EndD _
)
Link.HeadShape = ArrowHeads.Triangle
diaSchematic.Links.Add(Link)
Link.StrokeThickness = 8

End Sub

Stoyo,

Thanks, I never would have figured that out on my own!

By the way, you provide great support.  I hope you get paid a lot!
