[英]Div screenshot in asp.net
我想在asp.net中获取Div元素的屏幕截图并将其保存到磁盘。 我不想使用html2canvas库或html5 canvas元素。 方法可以是服务器端或客户端。
未经测试,但是发现了这一点:
public Bitmap GenerateScreenshot(string url, int width, int height)
{
// Load the webpage into a WebBrowser control
WebBrowser wb = new WebBrowser();
wb.ScrollBarsEnabled = false;
wb.ScriptErrorsSuppressed = true;
wb.Navigate(url);
while (wb.ReadyState != WebBrowserReadyState.Complete)
{
Application.DoEvents();
}
// Set the size of the WebBrowser control
wb.Width = width;
wb.Height = height;
if (width == -1)
{
// Take Screenshot of the web pages full width
wb.Width = wb.Document.Body.ScrollRectangle.Width;
}
if (height == -1)
{
// 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
Bitmap bitmap = new Bitmap(wb.Width, wb.Height);
wb.DrawToBitmap(bitmap, new Rectangle(0, 0, wb.Width, wb.Height));
wb.Dispose();
return bitmap;
}
