Google Street View WPF Application -- 1

將Google 街景圖以WPF之Image控制項展示。
1. 加入WIndowForm元件。 

// Add ref System.Drawing
//         System.Windows.Forms
2. 加入html2bitmap方法

        public System.Drawing.Bitmap SaveWebPage2Image(string url)
        {
            // Load the webpage into a WebBrowser control
            System.Windows.Forms.WebBrowser wb = new System.Windows.Forms.WebBrowser();
            wb.ScrollBarsEnabled = false;
            wb.ScriptErrorsSuppressed = true;
            wb.Navigate(url);

            while (wb.ReadyState != System.Windows.Forms.WebBrowserReadyState.Complete) { System.Windows.Forms.Application.DoEvents(); }

            // Take Screenshot of the web pages full width
            wb.Width = wb.Document.Body.ScrollRectangle.Width;

            // Take Screenshot of the web pages full height
            wb.Height = wb.Document.Body.ScrollRectangle.Height;

            // Get a Bitmap representation of the webpage as it's rendered in the WebBrowser control
            System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(wb.Width, wb.Height);
            wb.DrawToBitmap(bitmap, new System.Drawing.Rectangle(0, 0, wb.Width, wb.Height));
            wb.Dispose();

            return bitmap;
        }
3. 初始設定
        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            //convert System.Drawing.Image to WPF image
            System.Drawing.Bitmap bmp = SaveWebPage2Image(@"http://maps.googleapis.com/maps/api/streetview?size=600x300&location=25.080067,121.397699&heading=300&fov=90&pitch=-10&sensor=false");
            IntPtr hBitmap = bmp.GetHbitmap();
            System.Windows.Media.ImageSource WpfBitmap = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
            im.Source = WpfBitmap;
        }
4. MouseUp Event 改辦視角
        int angle1 = 120;
        private void Window_MouseUp(object sender, MouseButtonEventArgs e)
        {
            angle1 += 20;
            this.Title = "Headingangle : " + angle1.ToString();
            System.Drawing.Bitmap bmp = SaveWebPage2Image(@"http://maps.googleapis.com/maps/api/streetview?size=600x300&location=25.080067,121.397699&heading=" + angle1.ToString() + @"&fov=90&pitch=-10&sensor=false");
            IntPtr hBitmap = bmp.GetHbitmap();
            System.Windows.Media.ImageSource WpfBitmap = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(hBitmap, IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
            im.Source = WpfBitmap;
        }
    }
}
