    <p>I'm trying to create a poker chip like the one here: <a href="http://www.casinowholesalers.com/shop/product_info.php?cPath=57&amp;products_id=379" rel="noreferrer">http://www.casinowholesalers.com/shop/product_info.php?cPath=57&amp;products_id=379</a> using Expression Blend 4 for a WP7.1 Silverlight 4 app.</p> <p>I'm trying to create the six white "boxes" on the edge of the chip (ignoring for now the dice images and inner dashed line). The way I did it was two create two ellipses, one with no stroke, the other is the exact same size but with a stroke of 24, a color of White, and the StrokeDashArray to 1.8 (that's not "1 8", it's actually 1.8 with no second value). It looks pretty close to evenly sized and spaced (but not quite); I found it by trial and error. The XAML is below.</p> <pre><code>&lt;Grid x:Name="LayoutRoot" Background="Transparent"&gt; &lt;Grid.RowDefinitions&gt; &lt;RowDefinition Height="Auto"/&gt; &lt;RowDefinition Height="*"/&gt; &lt;/Grid.RowDefinitions&gt; &lt;Ellipse Fill="#FFC83838" Margin="112,253,128,275" Grid.Row="1" Stroke="#FFC83838" StrokeThickness="3"/&gt; &lt;Ellipse Fill="#FFC83838" Margin="112,253,128,275" Grid.Row="1" Stroke="White" StrokeThickness="30" StrokeDashArray="1.79" StrokeDashOffset="6" RenderTransformOrigin="0.5,0.5"/&gt; &lt;/Grid&gt; </code></pre> <p>I guess I have two questions:</p> <ol> <li>Is there a better way to create this shape besides using two ellipses?</li> <li>How can I mathematically determine what the StrokeDashArray value should be so the dashes are evenly spaced and sized instead of using trial and error?</li> </ol>

    1. CODepending on what you're doing with them (you haven't said) it may be easier, faster and use less memory to create images and use them instead.

    2. CO@MattLacey - I'm basically working on a version of the casino game craps, so I'm going to be creating instances of the chips all over the place: at the bottom of the UI which will symbolize the users "bank", I'll need to create an instance when they click/tap the screen to place a bet, I'll need to generate them in the UI for the payout if the user wins, etc. My plan is to create it as a user control and create new instances as needed. I'm open for suggestions. I have used images for other things - on the "Don't Come" bets and the hard ways bets, for example, I used images for the dice.
