Adding Machine

--------------

Simple XAML WPF app, taken from [Rob Miles' C# Yellow book](http://www.robmiles.com/c-yellow-book/).

Dispatcher Timer

----------------

Thought I would break down the main idea of sprite animation into timer and added on WriteableBitmap code.

Sprite Animation

----------------

Turns out that there are no simple examples of Sprite Animation using WPF/XAML. I wrote one that I think is pretty straightforward.

XAML

    

            xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

            xmlns:Properties="clr-namespace:SpriteAnimation.Properties" x:Class="SpriteAnimation.MainWindow"

            Title="MainWindow" Height="400" Width="555">

        

            

        

    

  

CS

      namespace SpriteAnimation

      {

          /// 

          /// Interaction logic for MainWindow.xaml

          /// 

          public partial class MainWindow : Window

          {

              WriteableBitmap writeableBitmap = null;

              BitmapImage bi = null;

              public MainWindow()

              {

                  InitializeComponent();

                  // DispatcherTimer setup

                  DispatcherTimer dispatcherTimer = new DispatcherTimer();

                  dispatcherTimer.Tick += new EventHandler(enterFrame);

                  dispatcherTimer.Interval = new TimeSpan(0, 0, 0, 0, 50);

                  dispatcherTimer.Start();

      

                  writeableBitmap = new WriteableBitmap(

                       (int)ImageControl.Width,

                       (int)ImageControl.Height,

                       96,

                       96,

                       PixelFormats.Pbgra32,

                       null);

                  ImageControl.Source = writeableBitmap;

                  bi = new BitmapImage(new Uri("pack://application:,,,/filmstrip.png"));

      

              }

              int nY = 0;

              private void enterFrame(object sender, EventArgs e)

              {

                  // Calculate stride of source

                  int nRowBytes = bi.PixelWidth * (bi.Format.BitsPerPixel / 8);

      

                  // Create data array to hold source pixel data

                  byte[] data = new byte[nRowBytes * 300];

      

                  // Copy source image pixels to the data array

                  bi.CopyPixels(new Int32Rect(0, nY*300, bi.PixelWidth, 300), data, nRowBytes, 0);

                  writeableBitmap.WritePixels(

                      new Int32Rect(0, 0, bi.PixelWidth, 300),

                      data, nRowBytes, 0);

                  if (++nY == 100) nY = 0;

              }

          }

      }

TDD Application

---------------

Simple TDD application using nUnit. The main example is TaxTest.cs and CanadianTax.cs.
