Answer 1

I make a demo to achieve your needs(A little ugly), here is running screenshot.

First, you need set the fresh-light image 's background is Transparent like this png(right click following image, save it).

Then I use following code, add red line in the background of fresh-light image.

   <Frame IsClippedToBounds="True" WidthRequest="200" HorizontalOptions="Center" HeightRequest="200" Padding="0" CornerRadius="100">  
               <Grid>  
                   <Rectangle   
                       x:Name="myrec"  
                       Fill="Red"  
                       HorizontalOptions="Start"  
                       VerticalOptions="Start"  
                       HeightRequest="10"  
                       WidthRequest="500"/>  
     
                   <Image Source="flashsymbol.png" Aspect="Fill"  WidthRequest="200" HeightRequest="200"></Image>  
     
                    
               </Grid>  
           </Frame>  

Then add Animation to Rectangle in the background.

   var animation = new Animation(v => myrec.TranslationY = v, 0, 200);  
     
               animation.Commit(this, "SimpleAnimation", 16, 1000, Easing.Linear, (v, c) => myrec.TranslationY = 0, () => true);

Hello,​

Welcome to our Microsoft Q&A platform!

Based on my research, If you execute the clip, you have four choose LineGeometry, PathGeometry, RectangleGeometry and EllipseGeometry.

You draw a Rectangle , then you want to clip it to Ellipse, PathorLine, why do not draw a Ellipse, Path or Line directly? This clip operation is meaningless.

Based on my view, this is by design,
