从微软欢乐图生成图像后，无论如何都可以获取图像映射的输入

我正在使用 microsoft glee 代码并生成一个图表，然后将其转换为 html 页面上的图像。我想看看是否可以在图像上自动生成图像映射代码，以便我能够单击图形节点的每个元素。

这是将 gle 图形代码转换为图像的示例。

   Graph g = new Graph("graph");
        g.GraphAttr.LayerDirection = LayerDirection.LR;
        g.GraphAttr.NodeAttr.Padding = 3;

        [Add a bunch of nodes . . .]

        GraphRenderer renderer = new GraphRenderer(g);
        renderer.CalculateLayout();

        //Bitmap bmp = new Bitmap(Convert.ToInt32(g.Width), Convert.ToInt32(g.Height), System.Drawing.Imaging.PixelFormat.Format32bppArgb);
        Bitmap bmp = new Bitmap(Convert.ToInt32(g.Width), Convert.ToInt32(g.Height),
                                System.Drawing.Imaging.PixelFormat.Format32bppArgb);
        renderer.Render(bmp);

所以问题是：有没有一种方法可以从 glee 图形对象或渲染器获取 html 图像映射所需的所有信息。

原文

i am taking microsoft glee code and producing a graph and then converting it to an image on an html page. i want to see if i can autogenerate image map code over the image so i am able to click on each element of the graph nodes.

Here is an example of the glee graph code converting to an image.

   Graph g = new Graph("graph");
        g.GraphAttr.LayerDirection = LayerDirection.LR;
        g.GraphAttr.NodeAttr.Padding = 3;

        [Add a bunch of nodes . . .]

        GraphRenderer renderer = new GraphRenderer(g);
        renderer.CalculateLayout();

        //Bitmap bmp = new Bitmap(Convert.ToInt32(g.Width), Convert.ToInt32(g.Height), System.Drawing.Imaging.PixelFormat.Format32bppArgb);
        Bitmap bmp = new Bitmap(Convert.ToInt32(g.Width), Convert.ToInt32(g.Height),
                                System.Drawing.Imaging.PixelFormat.Format32bppArgb);
        renderer.Render(bmp);

So the question is: is there a way to get all of the info that would be needed for an html image map from the glee graph object or the renderer.
