Take Partial Screenshots of Your Xamarin.Forms App - Extension methods for capturing images from UI

 

Extension methods for capturing images from UI . 

Nuget Required : 

https://www.nuget.org/packages/ImageFromXamarinUI/1.0.0-pre1 [install in all three projects]

This is how you can create a simple command to call CaptureImageAsync method

JUST CLICK ON CAPTURE IT WILL SHOW YOUR STACK LAYOUT OR SELECTED CONTROL
IN IMAGE VIEW.

public ImageSource ResultImageSource { get; set; }

public ICommand CaptureCommand  => new Command<Xamarin.Forms.VisualElement>(OnCapture);

async void OnCapture(Xamarin.Forms.VisualElement element)
{
    try
    {
        var stream = await element.CaptureImageAsync();
        ResultImageSource = ImageSource.FromStream(() => stream);
    }
    catch (Exception)
    {
        // Handle exception that share failed
    }        
}

You can pass in the calling element when the Command is triggered:

<StackLayout x:Name="rootView">
   <Button Text="Capture"
           Command="{Binding CaptureCommand}"
           CommandParameter="{x:Reference rootView}"/>
</StackLayout>
