.Net MAUI - Capturing Screenshots

Step 4. Open the MainPage.xaml.cs file and the page content as shown below:

namespace MauiTutorial6;

public partial class MainPage : ContentPage
{
	public MainPage()
	{
		InitializeComponent();
	}

	private async void OnCounterClicked(object sender, EventArgs e)
	{
        if (Screenshot.Default.IsCaptureSupported)
        {
            IScreenshotResult screen = await Screenshot.Default.CaptureAsync();
            Stream stream = await screen.OpenReadAsync();
            img.Source = ImageSource.FromStream(() => stream);
        }

        SemanticScreenReader.Announce("Image Captured");
	}
}

Step 5. Here

• Title: Notification Title
• Description: Notification Description
• Subtitle: Notification Subtitle for collapsed view
• Schedule: DateTime value to show the notification after the mentioned schedule
• Repeat: DateTime value to repeat the notification after the mentioned frequency

Step 6. IsCaptureSupported: Returns a bool value – Gets a value indicating whether the capturing screenshots are supported.

Step 7. CaptureAsync: Returns an ISscreenshotResult. – It is responsible for taking screenshots of the current application. Therefore, we can get various information about it, such as width and height.

Step 8. Stream: IScreenshotResult also has a Stream property that is used to convert the screenshot to an image object.

Step 9. Assign the derived stream value to the image control as ImageSource.
