You can do it easily with Expression Design which is included in Microsoft Expression Studio. This is steps you gonna do:
您可以使用 Microsoft Expression Studio 中包含的 Expression Design 轻松完成此操作。这是你要做的步骤：
- Add image to Expression Design.
- Then you can use PaintBrush tool for split image into parts as you want.
- Then you must export this to xaml. In export window you can choose Xaml Silverlight 3
- 将图像添加到表达式设计。
- 然后您可以使用 PaintBrush 工具根据需要将图像分割成多个部分。
- 然后您必须将其导出到 xaml。在导出窗口中，您可以选择 Xaml Silverlight 3
Canvas as format and Paths as Text.
画布作为格式和路径作为文本。
As you understand, it automatically converts objects you draw on your image to path object with all coordinates on it.
如您所知，它会自动将您在图像上绘制的对象转换为带有所有坐标的路径对象。
Then you can copy exported xaml and paste it to your application.
然后您可以复制导出的 xaml 并将其粘贴到您的应用程序中。
You can download Expression Studio from Dreamspark for free.
您可以从 Dreamspark 免费下载 Expression Studio。
I have just made sample and exported it to xaml:
我刚刚制作了示例并将其导出到 xaml：

The exported part is Path object. You can do whatever you want on it. For example you can handle MouseClick event for this path and change background of path....
导出的部分是路径对象。你可以为所欲为。例如，您可以处理此路径的 MouseClick 事件并更改路径的背景....

You could overlay the image with a set of transparent shapes:
您可以使用一组透明形状覆盖图像：
<Canvas>
<Image Source="..."/>
<Ellipse Canvas.Left="50" Canvas.Top="50" Width="100" Height="50"
Fill="Transparent" MouseDown="Ellipse_MouseDown"/>
<Path Data="..." MouseDown="Path_MouseDown"/>
</Canvas>
These shapes could be simple Rectangles or Ellipses, or more or less complex Polygons or Paths.
这些形状可以是简单的矩形或椭圆，也可以是或多或少复杂的多边形或路径。

Its very simple. rather than go to any complicated way follow this,It's simplest 1)First declare your image in XAML
它非常简单。与其采用任何复杂的方法，不如按照此操作，这是最简单的 1）首先在 XAML 中声明您的图像
<Grid Grid.Row="1" HorizontalAlignment="Center" VerticalAlignment="Center">
<Image Name="imagePath" HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Grid>
2)Find mouse position on image itself to get x and y co-ordinate
2）在图像本身上找到鼠标位置以获得x和y坐标
String[] arr = new String[2];
var mousePos = Mouse.GetPosition(imagePath);
arr = mousePos.ToString().Split(',');
double x = Double.Parse(arr[0].ToString());
double y = Double.Parse(arr[1].ToString());
3)Declare area where you wants to get clickable area or mousehover
3) 声明您想要获得可点击区域或鼠标悬停的区域
if (x >= 10 && y >= 10 && x <= 20 && y <= 20//this declares square area with x1,y1,x2,y2
{
//do whatever you want to do
//don't forget to add left and top each time
left = left +x;//x=10 i.e x1
top = top + y;//y=20 i.e y1
}
4)Add this x1 and y1 each time you move on image
4）每次移动图像时添加这个 x1 和 y1
int left = 0;
int top = 0;
Entire code;ll look like this
整个代码；看起来像这样
InitializeComponent();
imagePath.MouseMove += new MouseEventHandler(myMouseMove);
private void myMouseMove(object sender, MouseEventArgs e)
{
String[] arr = new String[2];
var mousePos = Mouse.GetPosition(imagePath);
arr = mousePos.ToString().Split(',');
double x = Double.Parse(arr[0].ToString());
double y = Double.Parse(arr[1].ToString());
int x = (int)xx;
int y = (int)yy;
int left = 0;
int top = 0;
Console.WriteLine("Screen Cordinate-------------------------" + x + ", " + y);
for (int i = 0; i < n; i++)
{
if (x >= x1 && y >= y1 && x <= x2 && y <= y2
{
Mouse.OverrideCursor = Cursors.Hand;
left = left + x1;
top = top + y1;
break;
}
else
{
Mouse.OverrideCursor = Cursors.Arrow;
}
}
where x1,y1,x2,y2 are the cordinates on image Thats it!!!
其中 x1,y1,x2,y2 是图像上的坐标

I think use Adorner to implement the funtions is best way.
我认为使用 Adorner 来实现这些功能是最好的方法。
Here is smaple for add control on image (image annotating) and Adorner overviewin MSDN
