Please take a look at my following code:
<Grid>
<Ellipse StrokeThickness="2" Stroke="White">
<Ellipse.Fill>
<ImageBrush ImageSource="someImage.png"/>
</Ellipse.Fill>
</Ellipse>
</Grid>
What I'm trying to do is to margin the someImage.png 5px from left and 5px from top. I'm wondering if it's possible as I couldn't find any margin property available.
You could put two Ellipses on top of each other like so:
<Grid>
<Ellipse StrokeThickness="2" Stroke="White"/>
<Ellipse Margin="5" StrokeThickness="2" Stroke="White">
<Ellipse.Fill>
<ImageBrush ImageSource="someImage.png"/>
</Ellipse.Fill>
</Ellipse>
</Grid>
The grid will put all the items in the same row/column on top of each other.

I've made a circle for display the status of a connection for my DB, it's working nice but I want to make it look like a bulb with glass effects.
<Canvas Visibility="Visible" x:Name="connection_red" Grid.Column="1">
<Ellipse
Fill="Red"
Height="13"
Width="13"
Margin="0,7,80,0"
StrokeThickness="1"
Stroke="White"/>
</Canvas>
I have visited many online tutorials, but they use too much code and I do not want to use 50 lines of code to achieve this effect. Someone knows how to do to get the effect glass bulb in a few lines of code? You can show me the way?
This is the actual preview:
You need to either specify the opacity seperately...
<Ellipse Fill="#FF0000" Opacity="0.25"
Height="130"
Width="130"
Margin="0,7,80,0"
StrokeThickness="1"
Stroke="White" />
...or use a SolidColorBrush...
<Canvas Visibility="Visible" x:Name="connection_red" Grid.Column="1">
<Ellipse Height="130"
Width="130"
Margin="0,7,80,0"
StrokeThickness="1"
Stroke="White">
<Ellipse.Fill>
<SolidColorBrush>
<SolidColorBrush.Color>
<Color A="25" R="255" G="0" B="0" />
</SolidColorBrush.Color>
</SolidColorBrush>
</Ellipse.Fill>
</Ellipse>
Would be good though if you could clarify exactly what type of effect you're after.
<Canvas Visibility="Visible" x:Name="connection_red" Grid.Column="1">
<Ellipse
Fill="#7FFF0000"
Height="13"
Width="13"
Margin="0,7,80,0"
StrokeThickness="1"
Stroke="White"/>
</Canvas>
When i draw items in canvas, the position is take from top of the item inside canvas:
<Canvas Name="cnvMain"
Width="80"
Height="80">
<Ellipse Canvas.Top="20"
Canvas.Left="40"
Width="40"
Height="40"
Fill="Gray" />
</Canvas>
Now what i would need is to take the measurement from the bottom of the element, like this:
In the end i would like to be able to set the distance from the bottom of the Ellipse to the top of the Canvas.
NB: Ellipse can sometimes not be a circle and flipping it upside down is not an option. Also i dont know the height before runtime so setting negative margin in xaml will not work also.
(Picture and example xaml taken from: http://weblogs.asp.net/psheriff/centering-text-within-a-wpf-shape-using-a-canvas)
If you want to specify the distance of the bottom of the Ellipse to the bottom of the Canvas, you could replace Canvas.Top by Canvas.Bottom:
<Ellipse Canvas.Bottom="20" Canvas.Left="40" Width="40" Height="40" Fill="Gray"/>
For the distance from the bottom of the Ellipse to the top of the Canvas, you may specify a negative Margin:
<Ellipse Canvas.Top="20" Canvas.Left="40" Width="40" Height="40" Fill="Gray"
Margin="0,-40,0,0"/>
or an appropriate RenderTransform:
<Ellipse Canvas.Top="20" Canvas.Left="40" Width="40" Height="40" Fill="Gray">
<Ellipse.RenderTransform>
<ScaleTransform ScaleY="-1"/>
</Ellipse.RenderTransform>
</Ellipse>
In order to invert the y direction of the whole Canvas coordinate system, you may apply a RenderTransform to the Canvas:
<Canvas ... RenderTransformOrigin="0,0.5">
<Canvas.RenderTransform>
<ScaleTransform ScaleY="-1"/>
</Canvas.RenderTransform>
...
</Canvas>
Edit: You may also put the Ellipse in another Canvas with zero Height, and attach it to the lower Canvas border:
<Canvas Canvas.Top="20" Canvas.Left="40" Width="0" Height="0">
<Ellipse Canvas.Bottom="0" Width="40" Height="40" Fill="Gray"/>
</Canvas>
I am using the MahApps Metro controls in a WPF application with their FlyOut control on the bottom of the window. I am using their MetroCircleButtonStyle button like so:
<Button Width="55"
Height="55"
VerticalAlignment="Top"
Style="{DynamicResource MetroCircleButtonStyle}">
<Rectangle Width="20"
Height="20">
<Rectangle.Fill>
<VisualBrush Stretch="Fill"
Visual="{StaticResource appbar_city}" />
</Rectangle.Fill>
</Rectangle>
</Button>
My question is how do I add Text below these icons in the flyout?
Steve
something like:
<Button Width="55"
Height="55"
VerticalAlignment="Top"
Style="{DynamicResource MetroCircleButtonStyle}">
<StackPanel Orientation="Vertical">
<Rectangle Width="20"
Height="20">
<Rectangle.Fill>
<VisualBrush Stretch="Fill"
Visual="{StaticResource appbar_city}" />
</Rectangle.Fill>
</Rectangle>
<TextBlock Text="Hello" />
</StackPanel>
</Button>
Update:
MetroCircleButtonStyle by itself does not accomodate for Text outside the Ellipse. It's Template is pretty much a Grid with 1 cell and 3 children on top of each other(Ellipse, Another Ellipse and top-most is the ContentPresenter). Text inside does not actually respond to any state change either, So text outside with this Style is as good as wrapping the Button without text with a TextBlock in say a StackPanel.
What you're looking for, you could use the AppBarButton. Do note the documentation states, Due to issues with this control, AppBarButton is due to be removed for v1.0 so use that as an example and build up your own control with a similar Style. Probably drop the ViewBox, if your Button sizes are fixed.
From Viv's answer, you can add margin on the textbox element to push the label down:
<Button Width="55"
Height="55"
VerticalAlignment="Top"
Style="{DynamicResource MetroCircleButtonStyle}">
<StackPanel Orientation="Vertical">
<Rectangle Width="20"
Height="20">
<Rectangle.Fill>
<VisualBrush Stretch="Fill"
Visual="{StaticResource appbar_city}" />
</Rectangle.Fill>
</Rectangle>
<TextBlock Text="Hello" Margin="0, 20, 0, 0" />
</StackPanel>
</Button>
<Grid Height="333">
<Canvas Margin="0,-41">
<Rectangle Height="60" Width="72" Canvas.Left="73" Canvas.Top="355">
<Rectangle.Fill>
<ImageBrush Stretch="None" ImageSource="aaa.png"/>
</Rectangle.Fill>
</Rectangle>
</Canvas>
</Grid>
The problem is Rectangle is visible out of the Grid and I don't want this.
What should I do?
You need to clip the Grid. I wrote an attached property that will do this for you. See the following blog post:
http://www.scottlogic.co.uk/blog/colin/2009/05/silverlight-cliptobounds-can-i-clip-it-yes-you-can/
You can use it as follows:
<Grid Height="333" util:Clip.ToBounds="true">
<Canvas Margin="0,-41">
<Rectangle Height="60" Width="72" Canvas.Left="73" Canvas.Top="355">
<Rectangle.Fill>
<ImageBrush Stretch="None" ImageSource="aaa.png"/>
</Rectangle.Fill>
</Rectangle>
</Canvas>
</Grid>
Internally this attached behaviour sets the FrameworkElement.Clip property to the required geometry based on the current size of the element it is attached to.

This XAML is from WPF – Easy rounded corners for anything but it doesn't work form me =(
<Border Canvas.Left="55"
Canvas.Top="30"
Width="100"
Height="Auto"
Margin="12,12,8,0"
VerticalAlignment="Top"
BorderBrush="#FF3B5998"
BorderThickness=".5"
CornerRadius="18">
<Border.Effect>
<DropShadowEffect BlurRadius="5"
Opacity=".5"
ShadowDepth="3" />
</Border.Effect>
<Border Name="ReceiverColor"
BorderBrush="#FF96B2E4"
BorderThickness="6"
CornerRadius="15">
<Border Name="Mask"
BorderBrush="#FF3B5998"
BorderThickness=".5"
CornerRadius="13">
<StackPanel>
<StackPanel.OpacityMask>
<VisualBrush Visual="{Binding ElementName=Mask}" />
</StackPanel.OpacityMask>
<Image Name="Receiver" />
</StackPanel>
</Border>
</Border>
</Border>
--- EDIT ---
I make borders sizes to auto and change source of image to an image from a link
when window loaded border size becomes as image size but image not shown !!!
You can define a <Border/> element and set its <Border.Background/>
property to an <ImageBrush/> , set the Borders CornerRadius property and you
are all set!
<Border CornerRadius="8,0,8,0">
<Border.Background>
<ImageBrush Stretch="Fill" ImageSource="ImageSource"/>
</Border.Background>
</Border>
You forgot the Grid that makes the mask and the image siblings and nested the image in the mask. and you forgot to set the background of the mask.
This works:
<Grid>
<Border Canvas.Left="55"
Canvas.Top="30"
Width="100"
Height="Auto"
Margin="12,12,8,0"
VerticalAlignment="Top"
BorderBrush="#FF3B5998"
BorderThickness=".5"
CornerRadius="18">
<Border.Effect>
<DropShadowEffect BlurRadius="5"
Opacity=".5"
ShadowDepth="3" />
</Border.Effect>
<Border Name="ReceiverColor"
BorderBrush="#FF96B2E4"
BorderThickness="6"
CornerRadius="15">
<Grid>
<Border Name="Mask"
Background="White"
BorderBrush="#FF3B5998"
BorderThickness=".5"
CornerRadius="13">
</Border>
<StackPanel>
<Image Name="Receiver"
Source="/Images/test.jpg" />
<StackPanel.OpacityMask>
<VisualBrush Visual="{Binding ElementName=Mask}" />
</StackPanel.OpacityMask>
</StackPanel>
</Grid>
</Border>
</Border>
</Grid>
in wpf this one works for me
<Ellipse Width="50" Height="50">
<Ellipse.Fill>
<ImageBrush ImageSource="http://chriscavanagh.files.wordpress.com/2006/12/chriss-blog-banner.jpg" />
</Ellipse.Fill>
</Ellipse>
None of the above answers worked for me completely. I was trying to implement rounded corners on image which could be resized and has properties Stretch="UniformToFill" VerticalAlignment="Center" and HorizontalAlignment="Center".
The center alignments keeps the middle part cropped as opposed to bottom and right side being cropped, when image is resized. Solutions with image brush were working but I was facing problem in keeping the content at center cropped.
The marked answer has a problem with transparent non rectangular images as the "mask" border will end up showing as white background. Following was the imlementation which worked for me:
<Grid>
<WrapPanel Name ="container">
<Image Source="sample_image.png" VerticalAlignment="Center" HorizontalAlignment="Center" Stretch="UniformToFill"/>
<WrapPanel.OpacityMask>
<VisualBrush >
<VisualBrush.Visual>
<Border Height="{Binding ElementName=container, Path=ActualHeight}"
Width="{Binding ElementName=container, Path=ActualWidth}"
Background="White" CornerRadius="15" />
</VisualBrush.Visual>
</VisualBrush>
</WrapPanel.OpacityMask>
</WrapPanel>
</Grid>
You can use an ellipse like how Usman Ali has said (I thought this myself and I didn't take it from him)
It's very simple, make an ellipse with the properties you want, then set the fill to an imagebrush with your desired image like this in XAML:
<Ellipse Height="Auto" Width="100">
<Ellipse.Fill>
<ImageBrush ImageSource="YOUR IMAGE SOURCE/LINK HERE"/>
</Ellipse.Fill>
</Ellipse>
In C#, if in any case you want to do in C#:
Ellipse YourEllipseName = new Ellipse
{
Height = 50,
Width = 50,
StrokeThickness = 0,
Fill = new ImageBrush
{
Stretch = Stretch.Uniform,
ImageSource = new BitmapImage(new Uri("YOUR IMAGE SOURCE HERE"))
}
};
<Grid Background="Black">
<Rectangle RadiusX="20" RadiusY="20"
Width="130"
Height="130">
<Rectangle.Fill>
<ImageBrush x:Name="myImage" ImageSource="C:\Path\Desktop\visual-studio-2010-logo.png"/>
</Rectangle.Fill>
</Rectangle>
</Grid>
