TouchAction event triggered overall entrire position of view, but in my case it triggered only in image area using AbsoluteLayout? But now it covered overall entire position of the view. how to achieve to only image position area

xaml code

<AbsoluteLayout x:Name="myabs"  >
            <local:CustomImage Source="{Binding PhotoSource}" AbsoluteLayout.LayoutBounds="0,0,1,1"
             AbsoluteLayout.LayoutFlags="All"Aspect="AspectFit"/>
            <views:SKCanvasView
            AbsoluteLayout.LayoutBounds="0,0,1,1"
             AbsoluteLayout.LayoutFlags="All"

            x:Name="canvasView" >
                <views:SKCanvasView.Effects>
                    <tt:TouchEffect Capture="True" TouchAction="TouchEffect_TouchAction" />
                </views:SKCanvasView.Effects>
            </views:SKCanvasView>
        </AbsoluteLayout>

Xaml.cs

private void TouchEffect_TouchAction(object sender, TouchTracking.TouchActionEventArgs args)
        {
            var x = args.Location.X;
            var y = args.Location.Y;
            var v = new View1();
            AbsoluteLayout.SetLayoutBounds(v, new Rectangle(x, y, 0.25, 0.25));
            AbsoluteLayout.SetLayoutFlags(v, AbsoluteLayoutFlags.SizeProportional);

            myabs.Children.Add(v);
        }

it covers the entire screen area in my scenario only triggered when I click image only

@JuanSturla edited and added above SkCanvasView covered entire screen how to set image area using AbsoluteLayout – newxamarin Oct 13 '21 at 11:02
@JuanSturla, Thanks for your reply. In SkCanvasView how to cover image part only – newxamarin Oct 13 '21 at 11:10
OH, so now it's working in the entire screen but you want only to work INSIDE the image? I got it backwards. Sorry about that. – Juan Sturla Oct 13 '21 at 11:16
@JuanSturla yes – newxamarin Oct 13 '21 at 11:20
Can't you just add that effect on your `CustomImage`? – Juan Sturla Oct 13 '21 at 11:20
@JuanSturla I don't know how to do that if any sample is there? – newxamarin Oct 13 '21 at 11:22
Something like you have in the XAML: ` ` – Juan Sturla Oct 13 '21 at 11:25
This will depend on the implementation of your `tt:TouchEffect` – Juan Sturla Oct 13 '21 at 11:26
@JuanSturla will check and let you know – newxamarin Oct 13 '21 at 11:30
@JuanSturla am using customeffects and also remove in – newxamarin Oct 13 '21 at 11:43
Do not delete the LayoutBounds and Flags, I did that just to keep the comment simple – Juan Sturla Oct 13 '21 at 11:46
@JuanSturla yes checking both scenario removed and not removed 1. if I removed it shows small and top position 2. if I not delete it covers entire screen till same issue occur – newxamarin Oct 13 '21 at 11:48
