在wpf应用程序开发中，为支持图标的矢量缩放，及在不同分辨率下界面中图标元素的矢量无损缩放，所以常常用到svg图标，那么如果完
美的将svg图标运用到wpf日常的项目开发中呢，这里分享一下我的个人使用经验和详细步骤。
步骤

- 1、SvgToXaml 工具
- 2、集成到资源字典
- 3、集成到控件中

1、SvgToXaml 工具
我经常使用一款开源的svg转xaml的工具，名字就叫做SvgToXaml，非常简单，可以直接把svg矢量图转换为wpf常规的xaml界面脚本，该工具开源，github的地址是 https://github.com/BerndK/SvgToXaml.git
使用方法也很简单，和日常的文件管理器使用方法一样，选中要转换的svg图标后直接就能转成xaml
有了xmal后就可以自由发挥了
2、集成到资源字典
接下来我们可以把转换得到了xaml 集成到资源字典中，新建一个IconDictionary.xaml，将xmal拷贝到资源字典中

</DrawingGroup>
</DrawingImage.Drawing>
</DrawingImage>
</ResourceDictionary>
然后再App.xaml中配置图标的资源字典
<Application x:Class="IconTest.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml">
<Application.Resources>
<!--引入资源库-->
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="IconDictionary.xaml"></ResourceDictionary>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
3、集成到控件中
之后就可以在界面中使用了,例如在按钮中加入矢量图标
<Button>
<Button.ToolTip>
<TextBlock Text="Open" FontSize="14" FontWeight="Bold" />
</Button.ToolTip>
<Image Source="{StaticResource svg_Open}" Margin="2,2,0,2" Height="20"></Image>
</Button>
我们可以看到，无论分辨率，和屏幕缩放级别怎么放大和缩小，图标依然是高清的，这就是矢量的魅力。
