Create snapshot of the graphics in the ViewControl

By Adam Nagy

I have an Autodesk.Navisworks.Api.Controls.ViewControl in my .NET application and would like to create a snapshot of the current view and save it to a bitmap.

Solution

You could simply use the .NET Framework to achieve that.

private void buttonSnapShot_Click(object sender, EventArgs e)
{
  Bitmap bmp = new Bitmap(
    viewControl.Bounds.Width, viewControl.Bounds.Height);
  Graphics graphics = Graphics.FromImage(bmp);
  // If you are stepping through the code and the debugger 
  // (or anything else) is in front of the ViewControl, 
  // then that will be captured instead
  graphics.CopyFromScreen(
    viewControl.PointToScreen(new Point(0, 0)),
    new Point(0, 0),
    new Size(bmp.Width, bmp.Height));
  bmp.Save("c:\test.bmp");
}
