XAML pour rotation, image ronde, avec centre transparent

Question

Je suis à la recherche de xaml qui peut représenter une icône de chargement, comme Vista fait.

description visuelle:

• rond (environ 1/3 pouce de largeur)
• bouton de gel plus léger de couleur bleu
• centrale transparente
• la recherche (bords arrondis wtih une petite ombre)
• spinner blanc autour du bord, pour donner le mouvement

light (er) ciel bleu/gel pack recherche

J'ai trouvé des rectangles tournants, et nous pouvons créer du XAML qui donne l'illusion de tourner, mais nous dessinons juste 12 parties d'une horloge, et animons chacun individuellement.

Voici un spinner super simple j'ai créé dans SL que vous pouvez convertir en WPF.

<UserControl x:Class="Spinner.MainPage"

      <DoubleAnimation To=".5" AutoReverse="True" BeginTime="0:0:0.125" Duration="0:0:.25" Storyboard.TargetName="e2" Storyboard.TargetProperty="Opacity"/>

     </Storyboard> 
    </UserControl.Resources> 
    <Grid x:Name="LayoutRoot" Background="White"> 
     <Grid Width="100" Height="100" x:Name="gridSpinner"> 
      <Ellipse x:Name="e1" Margin="40,80,0,0" Height="20" Width="20" Fill="Gray" Stretch="Fill" VerticalAlignment="Top" HorizontalAlignment="Left"/>

      <Ellipse x:Name="e4" Margin="12,12,0,0" Height="20" Width="20" Fill="Gray" Stretch="Fill" VerticalAlignment="Top" HorizontalAlignment="Left"/>

     </Grid> 
    </Grid> 
</UserControl> 

Answer 2

Faut-il absolument utiliser le format XAML complet? Pour ce genre d'effets, les PNG transparents fonctionnent parfaitement. Il suffit de superposer les fichiers PNG dans une grille et d'en animer certains en utilisant RotateTransform et DoubleAnimation.

Si votre application n'a pas besoin de zoomer beaucoup, ce sera la meilleure façon de faire l'affaire.

@Joeln, Merci, j'ai été en mesure de convertir cela en WPF, et obtenir ce dont j'avais besoin, merci.
