Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public PlayCtrlForm _form = new PlayCtrlForm(); 
public PlayCtrl _playctrl = null; 
public string _bmpFile = Path.Combine(LEAD_VARS.MediaDir, "PlayCtrl_SaveStillBitmap.bmp"); 
 
public void SaveStillBitmapExample() 
{ 
   // input and output file names 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "PlayCtrl_ShortSource.avi"); 
 
   try 
   { 
      // reference the convert control 
      _playctrl = _form.PlayCtrl; 
 
      // set a timer on the form to make the still bitmap 
      _form.TestTimer.Interval = 5000; 
      _form.TestTimer.Tick += new EventHandler(SaveStillBitmap_Helper); 
 
      // add an effects processor for playback 
      _playctrl.SelectedVideoProcessors.Add(_playctrl.VideoProcessors.EFXDizzy); 
 
      // set the still tap location to Processors so that we get 
      // our effect applied to the still image -- you could of course 
      // set the tap to Source to capture the still without the applied effect  
      _playctrl.StillTap = PlayStillTap.Processors; 
 
      // set the source and target files 
      _playctrl.SourceFile = inFile; 
 
      // now start the test timer for the still capture 
      _form.TestTimer.Start(); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
 
   // we'll loop on the state and pump messages for this example. 
   // but you should not need to if running from a Windows Forms application. 
   while (_playctrl.State == PlayState.Running) 
      Application.DoEvents(); 
} 
 
public void SaveStillBitmap_Helper(object sender, EventArgs e) 
{ 
   // cancel the timer 
   _form.TestTimer.Stop(); 
 
   // try to simulate an error condition 
   _playctrl.SaveStillBitmap(_bmpFile, StillFormatType.BMP, 0, 0, -1); 
 
   // check for the capture file and set the result 
   if (File.Exists(Path.Combine(Directory.GetCurrentDirectory(), _bmpFile))) 
      _result = true; 
 
   _playctrl.Stop(); 
}
