representing the normal way up. Fractional angles, negative angles, and angles greater than 360 degrees are all permitted and work as you would expect. Alongside the rotation angle are two additional properties, CenterX and CenterY, which control the point around which the rotation will take place. To rotate an object around its own center point, CenterX and CenterY will need to be set to be half the control s width and height, respectively. Listing 12 15 shows the XAML code to display an image that has been rotated by 22 degrees. Listing 12 15. Rotating an image <Image Height="150" Stretch="Fill" Width="150" Source="/WindowsPhoneApplication1;component/Images/SmileyFace.png"> <Image.RenderTransform> <RotateTransform Angle="22" CenterX="75" CenterY="75" /> </Image.RenderTransform> </Image> The resulting image, shown here in the page designer, can be seen in Figure 12 20. As you can see, the designer updates to show the object in its transformed position.

private void initWorld() { world = new World(); world.setGravity(0f, -0.2f, 0);

underlying tables is changed after the view has been created, the view will need to be updated; otherwise, queries to the view may return errors.

Figure 12 20. The rotated image Having the designer update to show the transformed layout is useful in most cases, but if you are applying transforms to any large objects, or to containers that you subsequently want to draw other controls inside, it can be quite awkward using a page designer full of rotated objects. In these situations, it might be better to apply the transform using code instead. This can be achieved by ensuring that your control has a name (image1 in this example) and then executing code in the PhoneApplicationPage_Loaded event handler, as shown in Listing 12 16. Listing 12 16. Applying a RotateTransform at runtime using C# code behind private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e) { image1.RenderTransform = new RotateTransform() { Angle = 22, CenterX = image1.Width / 2, CenterY = image1.Height / 2 }; } In addition to setting the angle, this code also programmatically calculates the center point of the image from its width and height, something that we cannot perform in XAML markup.

We ve already reviewed a few examples of a view representing data from a single table in Listings 12-2 and 12-4. In the following sections, we ll go through using multiple tables with a join and combining multiple SELECT statements with UNION. These techniques allow you to create complex views of the data.

UI elements can be scaled by applying a ScaleTransform, which allows a nonuniform scale transformation to be applied using the properties ScaleX and ScaleY to define the scale on each axis. Either of these properties can be omitted from the XAML to avoid scaling on that axis. Just as in XNA, a scale value of 1 keeps the size unchanged; setting a value of 0 will scale the object to have no size on that axis, causing it to vanish. Like RotateTransform, the ScaleTransform object also has CenterX and CenterY properties, so you can define the point around which the element will scale. Listing 12 17 shows the XAML required to scale an image to double its normal width and 1.5 times its height. No center point is specified, so it will scale from its local coordinate (0, 0); in other words, its top-left corner. Listing 12 17. Applying a ScaleTransform to an image control <Image x:Name="image1" Height="150" Stretch="Fill" Width="150" Source="/WindowsPhoneApplication1;component/Images/SmileyFace.png"> <Image.RenderTransform> <ScaleTransform ScaleX="2" ScaleY="1.5" /> </Image.RenderTransform> </Image>

// max interactions per step (bigger is more accurate, but slower) world.setStepInteractions(10); // set step size (smaller is more accurate, but slower) world.setStepSize(0.05f); // create a collision space for the world's geoms collSpace = new HashSpace(); collCalcs = new JavaCollision(world); // collision calculations contactInfo = new Contact( collCalcs.getContactIntBuffer(), collCalcs.getContactFloatBuffer()); } // end of initWorld() The World object acts as an environment for the bodies and joints, and manages gravity and step-related parameters. The HashSpace object is a collision space for geoms. Collision testing involves examining pairs of geoms in the space to see if they intersect. It s possible to create multiple collision spaces, which improves collision testing performance since testing is only done between geoms within the same space. JavaCollision performs the collision testing on geoms in a particular space. The tests generate a list of contact points, and the details relating to a particular point can be manipulated with the Contact object, contactInfo.
