Step 3

From the New Project window select Visual C# from Installed, Templates then select Blank App (Windows Universal) from the list, then type in a Name and select a Location to save to before selecting Ok to create the Project.

From the Add New Item window select Visual C# from Installed then select Code File from the list, then type in the Name as Library.cs before selecting Add to add the file to the Project

10-add-new-item-library

Step 6

Once in the Code View for Library.cs the following should be entered:

using System;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Media.Animation;

public class Library
{
    private bool rotating = false;
    private Storyboard rotation = new Storyboard();

    public void Rotate(string axis, ref Image target)
    {
        if (rotating)
        {
            rotation.Stop();
            rotating = false;
        }
        else
        {
            DoubleAnimation animation = new DoubleAnimation();
            animation.From = 0.0;
            animation.To = 360.0;
            animation.BeginTime = TimeSpan.FromSeconds(1);
            animation.RepeatBehavior = RepeatBehavior.Forever;
            Storyboard.SetTarget(animation, target);
            Storyboard.SetTargetProperty(animation, "(UIElement.Projection).(PlaneProjection.Rotation" + axis + ")");
            rotation.Children.Clear();
            rotation.Children.Add(animation);
            rotation.Begin();
            rotating = true;
        }
    }
}

It should then appear as such:

10-library-imagerotate

Step 7

From the Solution Explorer select MainPage.xaml

10-mainpage

Step 8

Select from the Menu, View then Designer

10-designer

Step 9

The Design View will be displayed along with the XAML View and in this above <Grid Background=”{ThemeResource ApplicationPageBackgroundThemeBrush}”> enter the following XAML:

<Page.BottomAppBar>
	<AppBar IsOpen="True" IsSticky="True">
		<StackPanel Orientation="Horizontal">
			<AppBarButton Icon="RepeatAll" Label="Pitch" Click="Pitch_Click"/>
			<AppBarButton Icon="Rotate" Label="Roll" Click="Roll_Click"/>
			<AppBarButton Icon="Refresh" Label="Yaw" Click="Yaw_Click"/>
		</StackPanel>
	</AppBar>
</Page.BottomAppBar>

While still in the XAML View below <Grid Background=”{ThemeResource ApplicationPageBackgroundThemeBrush}”>enter the following XAML:

<Grid>
	<Grid.RowDefinitions>
		<RowDefinition Height="Auto"/>
		<RowDefinition Height="*"/>
	</Grid.RowDefinitions>
	<TextBox Grid.Row="0" Name="Value" InputScope="Url" KeyDown="Go_KeyDown" Margin="20"/>
	<Image Grid.Row="1" Margin="60" Stretch="Uniform" Name="Display">
		<Image.Projection>
			<PlaneProjection/>
		</Image.Projection>
	</Image>           
</Grid>

It should appear as such:

10-xaml-imagerotate

Step 10

Select from the Menu, View then Code

10-code

Step 11

Once in the Code View below the public MainPage() { … } the following should be entered:

public Library Library = new Library();
 
private void Go_KeyDown(object sender, KeyRoutedEventArgs e)
{
    if (e.Key == Windows.System.VirtualKey.Enter)
    {
        Display.Source = new Windows.UI.Xaml.Media.Imaging.BitmapImage(new Uri(Value.Text));
    }
}
 
private void Pitch_Click(object sender, RoutedEventArgs e)
{
    Library.Rotate("X", ref Display);
}
 
private void Roll_Click(object sender, RoutedEventArgs e)
{
    Library.Rotate("Y", ref Display);
}
 
private void Yaw_Click(object sender, RoutedEventArgs e)
{
    Library.Rotate("Z", ref Display);
}

It should then appear as such:

10-code-imagerotate

Step 12

That completes the Windows Universal Application so Save the Project then select the Debug and Simulator option to run the Application

10-simulator

Step 13

Once the Simulator has started the Application should then appear

10-simulator-run-imagerotate

Step 14

Step 16

Another option is to run as a Windows Phone application, select Debug and select Emulator 10.0.1.0 WVGA 4 inch 512MB option to run the Application

Step 18

After the Application has started running you can then type in the URL of any image e.g. http://dummyimage.com/300×200&text=Hello+World then press or tap enter to load this, then use the Pitch, Roll or Yaw buttons to rotate the image
