WPF RotateTransform question on offset
In the following:
<Rectangle Height="60" HorizontalAlignment="Left" Margin="50,100,0,0" Name="rectangle2" Stroke="Black" VerticalAlignment="Top" Width="60" >
<Rectangle.RenderTransform>
<TransformGroup>
<RotateTransform Angle="45" CenterX="30" CenterY="30"/>
</TransformGroup>
</Rectangle.RenderTransform>

To rotate the rectangle on its centre I have to set the CenterX and Y to half of the Rectangle's size. Is there a way to do that in markup?
Something like CenterX="{Binding Path=Width\2}" ?
You can set RenderTrasformOrigin
property on the Rectangle
itself:
<Rectangle Height="60" HorizontalAlignment="Left" Margin="50,100,0,0" Name="rectangle2"
Stroke="Black" VerticalAlignment="Top" Width="60"
RenderTrasformOrigin="0.5,0.5">
<Rectangle.RenderTransform>
<TransformGroup>
<RotateTransform Angle="45" />
</TransformGroup>
</Rectangle.RenderTransform>
