GDI+入门（九、ASP.NET中GDI+）

九、ASP.NET中GDI+
protected void Page_Load(object sender, EventArgs e)
        {
            string Filename;
            System.Drawing.Image g;
            Filename = Server.MapPath("./1.jpg");
            g = System.Drawing.Image.fromFile(Filename);
            Response.ContentType = "image/jpeg";
            g.Save(Response.OutputStream, g.RawFormat);
            g.Dispose();
        }
实在是太简单了，不讲了吧
Response.ContentType = "image/jpeg";
Response.OutputStream
这两个地方很重中
 
WebServices中使用GDI+
[WebMethod]
        public Byte[] DrawChart(int north, int east, int south, int west)
        {
            System.IO.MemoryStream outStream;
            outStream = new System.IO.MemoryStream();
            float thisAngle = 0;
            float totalAngle = 0;
 
            int width = 200;
            int height = width;
            int diameter = width - (width / 10);
            int top = (height / 2) - (diameter / 2);
