title: WPF Change SplineThicknessKeyFrame value?
body: <p>Im new in WPF, please if somebody can give me some tips to do this:</p>
  
  <p>I need to move some images from to left or right, like in a coverflow (carousel, i can't use component as Dev Express, i have to do it for myself). And i need that if i maximize the window the "carousel" expand too and keep relation between margins of the images.</p>
  
  <p>I try it moving the images in a Canvas, but when i maximize the window the Canvas dont do it and keep little.. I read and understand that i can't do that with a Canvas, so i do it putting the images on grids and changing its margin property, its works but when i maximize, the margin still is the same that when images are little and the aspect ratio is loose.</p>
  
  <p>So my question is, how can i change the margin too when i maximize the window?</p>
  
  <p>My code to move images using margin is:</p>
  
  <pre><code>&lt;Storyboard Name="FlowIzq"&gt;
     &lt;ThicknessAnimationUsingKeyFrames Storyboard.TargetProperty="Margin" Storyboard.TargetName="Image1" BeginTime="00:00:00"&gt;
  &lt;SplineThicknessKeyFrame    KeyTime="00:00:00"  Value="0,0,0,0"/&gt;
  &lt;SplineThicknessKeyFrame    KeyTime="00:00:0.5" Value="-157, 0,157,0"/&gt;
  &lt;/ThicknessAnimationUsingKeyFrames&gt;
  
  &lt;/Storyboard&gt;
  &lt;/BeginStoryboard.Storyboard&gt;
  </code></pre>
  
  <p>I think i need to change the value of all SplineThicknessKeyFrame, but how i do that?</p>
  
  <p>I hope explain it well and somebody can help me (sorry for my english) if something is not understood i explain it again.</p>
  
  <p>Peace,
  Rob.</p>
