Symbol Brush Clipped

Hi,

We have an issue where the user has increased a SimpleLine symbol width to say 40 and the brush appears to be clipped off around the edges.

This can be demonstrated by changing the code here: http://www.arcgis.com/home/item.html?id=1e432da7e74f4402bd43a5863167022d

to include these two symbols:
[HTML]new SymbolInfo
{
Label = "Simple thin Line",
Symbol = new LineSymbol
           {
               Color = lineColor,
      Width = 8
           }
},
new SymbolInfo
{
Label = "Simple thick Line",
Symbol = new LineSymbol
           {
               Color = lineColor,
      Width = 40
           }
},[/HTML]

In this picture I have drawn two similar lines with the different symbols:

Notice the clipping on the thick one. However when I zoom in, for just a second, it appears correct and then gets clipped as the zoom completes:

Can anyone suggest how this might be resolved?

BTW I have played with some settings in Blend:

The pictures show:

Thin line

Thick line

Thick line with width and height set to auto

Thick line with Stretch set to fill

It looks like number 2 represents the problem and number 3 is what I'm after. I am already using a custom control template for this symbol so I tried setting the width/height to auto. No luck!

Suggestions please!

Thanks Matthew

A (weird!) workaround may be to redefine the symbol controltemplate and to surround the path element with a canvas.

Example in XAML:

 
<esri:LineSymbol x:Key="RedLineSymbol" Color="Red" Width="40" >
  <esri:LineSymbol.ControlTemplate>
    <ControlTemplate>
      <Canvas>
        <Path x:Name="Element"
          Stroke="{Binding Symbol.Color}"
          StrokeThickness="{Binding Symbol.Width}"
          StrokeDashCap="Round"
          StrokeStartLineCap="Round"
          StrokeLineJoin="Round"
          StrokeEndLineCap="Round"/>
     </Canvas>
    </ControlTemplate>
  </esri:LineSymbol.ControlTemplate>
</esri:LineSymbol>

That did the trick, thanks.

Interestingly the clipping now appears during the zoom (which is more acceptable).

Is this something ESRI might address with the next release?

Likely not in the next release, but we'll consider that for a future release.

Thanks.
