Question

I need to apply multiple transform effect via c# in WPF.

I have tried code below but I see the last effect only and not the both together.

Any clue if it is possible to do?

XAML

<Grid>
   <Rectangle Fill="#FFF4F4F5" Name="rect" HorizontalAlignment="Left" Height="225" Margin="84,39,0,0" Stroke="Black" VerticalAlignment="Top" Width="299"/>
</Grid>

C#

SkewTransform skewTransform1 = new SkewTransform(45, 0, -50, 50);
rect.RenderTransform = skewTransform1;

RotateTransform rotateTransform  = new RotateTransform(30);
rect.RenderTransform = rotateTransform;

Answer 1

You have to combine both effects in a TransformGroup instead of overwriting them each time:

var transformGroup = new TransformGroup(); 
var skewTransform = new SkewTransform(45, 0, -50, 50); 
var rotateTransform = new RotateTransform(30); 

transformGroup.Children.Add(skewTransform); 
transformGroup.Children.Add(rotateTransform); 

rect.RenderTransform = transformGroup;
