SharpGIS博客翻译2006年7月：使用XAML来渲染地图

Using XAML for rendering maps [原文] [翻译] [作者：Clark]

Using XAML for rendering maps

I was just reading a few articles on XAML - Microsoft new UI language for rendering vector content and user interfaces - when it hit me that this probably can get you much further in web mapping interaction than SVG can. XAML is part of the "Windows Presentation Foundation" a part of .NET Framework 3.0

最近读了几篇关于XAML（微软用于渲染矢量图形和用户界面的新一代UI语言）的文章，我想它可能比SVG在WEB应用程序的交互上更有前途。XAML 是.NET Framework3.0中"Windows Presentation Foundation"的一部分。

My first attempt to generate XALM was done by creating a new renderer for SharpMap, and below you can see my first results in XamlPad. The data here has been created based on a SharpMap map by my quick'n'dirty XamlRenderer for SharpMap.

我开始尝试为SharpMap写一个新的renderer用来生成XAML，下图是在XamlPad查看生成的结果。这些数据是基于SharpMap的XamlRenderer生成的，代码有点混乱。




All it takes with the new renderer is initializing the new renderer with your map, and request a new map:

SharpMap.Xaml. Renderer XamlRenderer = new SharpMap.Xaml. Renderer (map);

string xaml = XamlRenderer.GetMap();

If you zip the generated XAML file you even get a 20% reduction over a PNG image.

Next step is to add interaction like zooming, querying etc…



你只需要用自己的地图实例化一个XamlRenderer，然后请求地图就可以得到这些数据，代码如下：

SharpMap.Xaml. Renderer XamlRenderer = new SharpMap.Xaml. Renderer (map);

string xaml = XamlRenderer.GetMap();

如果压缩一下生成的XAML文件，大约有20%的压缩率比PNG图片的压缩比还大。

下一步就是加入与其的交互了，如放大、查询等等。。。
