WPF DeepZoom 研究记录

以前搞silverlight的时候deepzoom挺酷的，这几天玩WPF的时候居然发现不支持deepzoom。这不是开玩笑么。google了几回，找到个开源的deepzoom for wpf 。这个控件配合Deep Zoom Composer确实可以实现。不过貌似只能用单张图片导出。

不过这样只能依靠Deep Zoom Composer，如果是动态的图片呢？不方便。于是反编译了下Deep Zoom Composer。大概研究了下，没有注释看的我蛋疼啊==!。

折腾了一下午终于实现了图片的导出，不过只能导出一张，几张合并的时候还是不行，先这样吧。

public  class DZImageHelper

   {

       public  static  void CreateImage(string dest)

       {

           var imgList = new List<Image>();

           imgList.Add( new Image("E:\\IMGTEST\\1.jpg"));



           var creator = new SparseImageCreator();

           SetCommonImageCreatorParams(creator);



           try

           {

               creator.Create(imgList, dest + "\\output");

           }

           catch (Exception ex)

           {

               throw ex;

           }

       }



       private static void SetCommonImageCreatorParams(CreatorBase creator)

       {

           creator.TileFormat = ImageFormat.Jpg;

           creator.ImageQuality = 0.5;

           creator.TileOverlap = 1;

           creator.TileSize = 64;

       }

   }

窗体：

<Window x:Class="DeepZoomForWPF.MainWindow"

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

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

        xmlns:Controls="clr-namespace:DeepZoom.Controls;assembly=DeepZoom" Title="MainWindow" Height="600" Width="1000"

         Loaded="Window_Loaded">

    <Grid>

        <Controls:MultiScaleImage x:Name="msi" Width="Auto" Height="Auto"/>

    </Grid>

</Window>



后台代码：

using System;

using System.Windows;

using DeepZoom;





namespace DeepZoomForWPF

{

    /// <summary>

    /// MainWindow.xaml 的交互逻辑

    /// </summary>

    public partial class MainWindow : Window

    {

        public MainWindow()

        {

            InitializeComponent();



            string dest = AppDomain.CurrentDomain.BaseDirectory;

            DZImageHelper.CreateImage(dest);

        }



        private void Window_Loaded(object sender, RoutedEventArgs e)

        {

            string url = AppDomain.CurrentDomain.BaseDirectory + "output.xml";

            this.msi.Source = new DeepZoomImageTileSource(new Uri( url, UriKind.Absolute));

        }

    }

}
