如何用C＃和WebKit.NET捕获完整的网站截图？
我正在使用WebKit.NET在我的C＃应用程序中集成浏览器组件。 问题是我只能用截图捕获浏览器窗口中的可见部分。 有没有办法捕获整个页面的屏幕截图？
似乎通过使用NativeMethods.SendMessage可能有点可能，虽然这会搞乱消息队列，你可以使用http://cutycapt.sourceforge.net/或者http://iecapt.sourceforge.net/或http： //labs.awesomium.com/capturing-web-pages-with-c-net/ ？
我改用WebBrowser; ScrollBarsEnabled = false让我捕获整个页面。
这是一些代码：
protected override void Render(HtmlTextWriter writer) { StringBuilder builder = new StringBuilder(); HtmlTextWriter htw = new HtmlTextWriter(new StringWriter(builder)); base.Render(htw); string html = builder.ToString(); _Generate(html); } private void _Generate(string html) { var browser = new WebBrowser { ScrollBarsEnabled = false }; DisplayHtml(html, browser); browser.DocumentCompleted += WebBrowser_DocumentCompleted; while (browser.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); browser.Dispose(); } private void DisplayHtml(string html, WebBrowser browser) { browser.Navigate("about:blank"); if (browser.Document != null) { browser.Document.Write(string.Empty); } browser.DocumentText = html; }
试试这个：
using System.IO; using System.Drawing; using System.Drawing.Imaging; using System.Threading; using System.Windows.Forms; public byte[] picbytes; private void capture_Click(object sender, EventArgs e) { makepicture(txtURL.Text.Trim()); pictureBox1.Visible = true; pictureBox1.Image = ByteToImage(picbytes); } private void makepicture(string url) { Thread thread = new Thread(delegate() { using (WebBrowser browser = new WebBrowser()) { browser.ScrollBarsEnabled = false; browser.AllowNavigation = true; browser.Navigate(url); browser.Width = 1024; browser.Height = 1575; browser.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(DocumentCompleted); while (browser.ReadyState != WebBrowserReadyState.Complete) { System.Windows.Forms.Application.DoEvents(); } } }); thread.SetApartmentState(ApartmentState.STA); thread.Start(); thread.Join(); } private void DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser browser = sender as WebBrowser; using (Bitmap bitmap = new Bitmap(browser.Width, browser.Height)) { browser.DrawToBitmap(bitmap, new System.Drawing.Rectangle(0, 0, browser.Width, browser.Height)); using (MemoryStream stream = new MemoryStream()) { bitmap.Save(stream, System.Drawing.Imaging.ImageFormat.Png); byte[] bytes = stream.ToArray(); picbytes = bytes; } } } public static Bitmap ByteToImage(byte[] blob) { MemoryStream mStream = new MemoryStream(); byte[] pData = blob; mStream.Write(pData, 0, Convert.ToInt32(pData.Length)); Bitmap bm = new Bitmap(mStream, false); mStream.Dispose(); return bm; }
