Image Animation with a Button WPF - wpf

I have an image within a button, I've wrote an animation that leads to Grow or Shrink When IsMouseOver Occurs, However I dont want the button itself Grows or Shrinks but the Image within the Button has to Grow or Shrink. Do you have any idea? I am all yours.
here is my .XAML
<Button Margin="355,0,0,0" Width="100" Height="300" Click="Button_Click_1">
<Image Source="img/blue.jpg" />
<Button.Style>
<Style TargetType="Button">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ThicknessAnimation Duration="0:0:0.250" To="0"
Storyboard.TargetProperty="BorderThickness" />
<DoubleAnimation Duration="0:0:0.350" To="320"
Storyboard.TargetProperty="Height" />
<DoubleAnimation Duration="0:0:0.350" To="120"
Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<ThicknessAnimation Duration="0:0:0.250" To="0"
Storyboard.TargetProperty="BorderThickness" />
<DoubleAnimation Duration="0:0:0.550" To="300"
Storyboard.TargetProperty="Height" />
<DoubleAnimation Duration="0:0:0.550" To="100"
Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>

You can simply apply the Style to the Image instead of the Button.
<Button ...>
<Image ...>
<Image.Style>
<Style TargetType="Image">
<Style.Triggers>
<!-- You get the idea -->
Note that Image does not have a Border control, therefore you can't use the BorderThickness animation on the Image, you can instead apply this animation on the Button as you were doing before.
Also, your Image will require a Height in order to animate. Otherwise, you can use the From property on the DoubleAnimation like this:
<DoubleAnimation Duration="0:0:0.350" From="300" To="320"
Storyboard.TargetProperty="Height" />

You have to give Height and Width to Image, else will get an Exception. As Mike said can't use BorderThickness.
<Button>
<Image Source="Edit.png" Height="50" Width="50">
<Image.Style>
<Style TargetType="Image">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<!--<ThicknessAnimation Duration="0:0:0.250" To="0" Storyboard.TargetProperty="BorderThickness" />-->
<DoubleAnimation Duration="0:0:0.350" To="320" Storyboard.TargetProperty="Height" />
<DoubleAnimation Duration="0:0:0.350" To="120" Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<!--<ThicknessAnimation Duration="0:0:0.250" To="0" Storyboard.TargetProperty="BorderThickness" />-->
<DoubleAnimation Duration="0:0:0.550" To="300" Storyboard.TargetProperty="Height" />
<DoubleAnimation Duration="0:0:0.550" To="100" Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</Style.Triggers>
</Style>
</Image.Style>
</Image>
</Button>

Or you could try this
<Button Margin="355,0,0,0" Width="100" Height="300" Click="Button_Click_1">
<Border Width="50" Height="150">
<Border.Style>
<Style TargetType="Border">

<Trigger Property="IsMouseOver" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>

<DoubleAnimation Duration="0:0:0.350" To="320"
Storyboard.TargetProperty="Height" />
<DoubleAnimation Duration="0:0:0.350" To="120"
Storyboard.TargetProperty="Width" />

My question is, how can use it for the rectangle ??
Or how do i change the Fill color of a rectangle on mouse over?? Not just changing the color, but fading in the color...is it possible?
Fixed it myself :
<Rectangle.Style>
<Style TargetType="Rectangle">
<Style.Triggers>
<EventTrigger RoutedEvent="Rectangle.MouseEnter">
<BeginStoryboard>
<Storyboard>
<ParallelTimeline >
<ColorAnimation Storyboard.TargetProperty="Fill.Color" To="#FF767C84" />
</ParallelTimeline>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
<EventTrigger RoutedEvent="Rectangle.MouseLeave">
<BeginStoryboard>
<Storyboard>
<ParallelTimeline >
<ColorAnimation Storyboard.TargetProperty="Fill.Color" To="#FF5C626C" />
</ParallelTimeline>
</Storyboard>

</EventTrigger>
</Style.Triggers>
</Style>
</Rectangle.Style>

Button Animation WPF

Hello I am trying to make an animation on button, it does increase the width and height on IsMouseOver, However, when the IsMouseOver is false, It does not return to its Original place with an animation.
here is my .XAML
<Grid>
<Button Margin="355,0,0,0" Width="100" Height="300">
<Image Source="img/blue.jpg" />
<Button.Style>
<Style TargetType="Button">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ThicknessAnimation Duration="0:0:0.250" To="0"
Storyboard.TargetProperty="BorderThickness" />
<DoubleAnimation Duration="0:0:0.550" To="320"
Storyboard.TargetProperty="Height" />
<DoubleAnimation Duration="0:0:0.550" To="120"
Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
<Trigger Property="IsMouseOver" Value="False">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ThicknessAnimation Duration="0:0:0.250" To="0"
Storyboard.TargetProperty="BorderThickness" />
<DoubleAnimation Duration="0:0:0.550" To="300"
Storyboard.TargetProperty="Height" />
<DoubleAnimation Duration="0:0:0.550" To="100"
Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
</Grid>
You should place animation to Trigger.ExitActions like this.
<Button.Style>
<Style TargetType="Button">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ThicknessAnimation Duration="0:0:0.250" To="0"
Storyboard.TargetProperty="BorderThickness" />
<DoubleAnimation Duration="0:0:0.550" To="120"
Storyboard.TargetProperty="Height" />
<DoubleAnimation Duration="0:0:0.550" To="120"
Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<ThicknessAnimation Duration="0:0:0.250" To="0"
Storyboard.TargetProperty="BorderThickness" />
<DoubleAnimation Duration="0:0:0.550" To="100"
Storyboard.TargetProperty="Height" />
<DoubleAnimation Duration="0:0:0.550" To="100"
Storyboard.TargetProperty="Width" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</Style.Triggers>

WPF Rectangle Triggers when Visible for DoubleAnimation StoryBoard

I have a DoubleAnimation which fades in/out a Rectangle in WPF
<Canvas>
<Rectangle Height="150" Width="150">
<Rectangle.Fill>
<SolidColorBrush x:Name="OpacityBrush" Color="DarkBlue" />
</Rectangle.Fill>
<Rectangle.Triggers>
<EventTrigger RoutedEvent="Rectangle.Loaded">
<BeginStoryboard>
<StoryBoard>
<DoubleAnimation Storyboard.TargetName="OpacityBrush" Storyboard.TargetProperty="Opacity" From="0.0" To="0.6" Duration="0:0:5" AutoReverse="True" RepeatBehavior="Forever" />
<DoubleAnimation Storyboard.TargetName="OpacityBrush" Storyboard.TargetProperty="Opacity" From="0.6" To="0.0" Duration="0:0:5" AutoReverse="True" RepeatBehavior="Forever" />
</StoryBoard>
</BeginStoryboard>
</EventTrigger>
</Rectangle.Triggers>
</Rectangle>
</Canvas>
This works fine but I want this to happen only when the rectangle is visible. Currently, it animates (I assume) in the background when it loads.
How can I change it so that it would start animation when it is visible and stop when it is hidden/collapse?
Or does it not matter? I'm just worried that it would take up resources (for the animation) as there are a lot of rectangles in the application and most of the time they are hidden.
Thanks.
Try this

How do you keep an item at the same point on a Canvas in XAML as it grows or shrinks in size?

I have the following xaml that illustrates a circle that grows and shrinks in size. I want my center point of my circle to stay put on my canvas as the animation runs.
<Window.Triggers>
<EventTrigger RoutedEvent="Window.Loaded">
<EventTrigger.Actions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation RepeatBehavior="Forever" AutoReverse="True" From="10" To="360" Duration="0:0:3" Storyboard.TargetName="GrowMe" Storyboard.TargetProperty="Width"/>
<DoubleAnimation RepeatBehavior="Forever" AutoReverse="True" From="10" To="360" Duration="0:0:3" Storyboard.TargetName="GrowMe" Storyboard.TargetProperty="Height"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger.Actions>
</EventTrigger>
</Window.Triggers>
<Canvas Width="640" Height="480">
<Ellipse Width="10" Height="10" Stroke="Red" Canvas.Left="80" Canvas.Top="31"/>
<Ellipse x:Name="GrowMe" Width="10" Height="10" Stroke="Cyan" Canvas.Left="205" Canvas.Top="203"/>
Here is an example of a button that does exactly this. Note the RenderTransformOrigin property.
<Button RenderTransformOrigin="0.5,0.5" Command="{Binding ClickCommand}" Cursor="Hand">
<Button.RenderTransform>
<ScaleTransform ScaleX="1" ScaleY="1" />
</Button.RenderTransform>
<Button.Template>
<ControlTemplate>
<Label>
<Label.Background>
<VisualBrush Visual="{Binding Path=Shape, Converter={StaticResource myTestConv}}" />
</Label.Background>
</Label>
</ControlTemplate>
</Button.Template>
<Button.Style>
<Style TargetType="Button">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="true">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="RenderTransform.ScaleX"
To="1.3" Duration="0:0:0.1" AccelerationRatio="0.5"/>
<DoubleAnimation Storyboard.TargetProperty="RenderTransform.ScaleY"
To="1.3" Duration="0:0:0.1" AccelerationRatio="0.5"/>
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="RenderTransform.ScaleX"
To="1" Duration="0:0:0.5"/>
<DoubleAnimation Storyboard.TargetProperty="RenderTransform.ScaleY"
To="1" Duration="0:0:0.5"/>
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
<local:TooltipServiceEx.ToolTipEx>
<local:ToolTipEx
HideToolTipTimeout="{StaticResource TooltipTimeout}" />
</local:TooltipServiceEx.ToolTipEx>
<ToolTipService.ToolTip>
<ToolTip
Template="{StaticResource EventTooltipStyle}" />
</ToolTipService.ToolTip>
</Button>
You can do it easily animating ScaleTransform inside RenderTransform and set RenderTransformOrigin = "0.5, 0.5".
--EDIT--
Then your change your storyboard to following:
<Storyboard>
<DoubleAnimation RepeatBehavior="Forever" AutoReverse="True" From="10" To="180" Duration="0:0:3" Storyboard.TargetName="GrowMe" Storyboard.TargetProperty="Width"/>
<DoubleAnimation RepeatBehavior="Forever" AutoReverse="True" From="10" To="180" Duration="0:0:3" Storyboard.TargetName="GrowMe" Storyboard.TargetProperty="Height"/>
<DoubleAnimation RepeatBehavior="Forever" AutoReverse="True" By="-180" Duration="0:0:3" Storyboard.TargetName="GrowMe" Storyboard.TargetProperty="(Canvas.Left)"/>
<DoubleAnimation RepeatBehavior="Forever" AutoReverse="True" By="-180" Duration="0:0:3" Storyboard.TargetName="GrowMe" Storyboard.TargetProperty="(Canvas.Top)"/>
</Storyboard>
You need to devide your growth into half and add it to Width/Height and subtract it from Left/Top.

Trigger Animations

I have a usercontrol that when I double click on it, I want it to zoom in, if it's not already. If it is, then the double click will zoom out on it. I can get it to work with code behind, but I can't get it to work in xaml.
Here is the code behind that handle's the double click event.
void MyObjectMouseDoubleClick(object sender, MouseButtonEventArgs e)
{
if (IsZoomedIn)
{
IsZoomedIn = false;
//ZoomOutAnimation();
}
else
{
IsZoomedIn = true;
//ZoomInAnimation();
}
}
then in my xaml:
<UserControl.RenderTransform>
<TransformGroup>
<RotateTransform />
<ScaleTransform />
<TranslateTransform />
</TransformGroup>
</UserControl.RenderTransform>
<UserControl.Style>
<Style>
<Style.Triggers>
<Trigger Property="local:MyObject.IsZoomedIn" Value="False">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="(UserControl.
RenderTransform).(TransformGroup.Children)[1].
(ScaleTransform.ScaleX)" To="1" Duration="0:0:.3" />
<DoubleAnimation Storyboard.TargetProperty="(UserControl.
RenderTransform).(TransformGroup.Children)[1].
(ScaleTransform.ScaleY)" To="1" Duration="0:0:.3" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
<Trigger Property="local:MyObject.IsZoomedIn" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="(UserControl.
RenderTransform).(TransformGroup.Children)[1].
(ScaleTransform.ScaleX)" To="2" Duration="0:0:.3" />
<DoubleAnimation Storyboard.TargetProperty="(UserControl.
RenderTransform).(TransformGroup.Children)[1].
(ScaleTransform.ScaleY)" To="2" Duration="0:0:.3" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
</Style.Triggers>
</Style>
</UserControl.Style>
Once it zooms in on my usercontrol, the zoom out animation doesn't work. Any help appreciated.
Thanks.
Your animations are holding the values, and so the second animation isn't appearing even though the trigger is firing. Instead of having two separate triggers, you can use the Trigger.ExitActions like you are using the EnterActions.
<Trigger Property="IsZoomedIn"
Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard >
<DoubleAnimation Storyboard.TargetProperty="(UserControl.RenderTransform).(TransformGroup.Children)[1].(ScaleTransform.ScaleX)"
To="2"
Duration="0:0:.3" />
<DoubleAnimation Storyboard.TargetProperty="(UserControl.RenderTransform).(TransformGroup.Children)[1].(ScaleTransform.ScaleY)"
To="2"
Duration="0:0:.3" />
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<DoubleAnimation Storyboard.TargetProperty="(UserControl.RenderTransform).(TransformGroup.Children)[1].(ScaleTransform.ScaleX)"
To="1"
Duration="0:0:.3" />
<DoubleAnimation Storyboard.TargetProperty="(UserControl.RenderTransform).(TransformGroup.Children)[1].(ScaleTransform.ScaleY)"
To="1"
Duration="0:0:.3" />
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
