SaveStillDIB Method

Summary

Saves a snapshot from the running stream to a file as a device-independent bitmap(DIB).

Syntax

C++/CLI

public virtual void SaveStillDIB( 
   string fileName, 
   int timeOut 
)

public: 
virtual void SaveStillDIB(  
   String^ fileName, 
   int timeOut 
)

Parameters

fileName
A string that represents the filename to which to save the DIB.

timeOut
The timeout period in milliseconds. This method fails if it is not able to take the DIB in the specified time. Use -1 to wait infinitely until a DIB is snapped.

Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public CaptureCtrlForm _form = new CaptureCtrlForm(); 
public CaptureCtrl _capturectrl = null; 
 
public bool _result = false; 
string _dibFile = Path.Combine(LEAD_VARS.MediaDir, "CaptureCtrl_SaveStillDIB.dib"); 
 
public void SaveStillDIBExample() 
{ 
   // reference the capture control 
   _capturectrl = _form.CaptureCtrl; 
 
   try 
   { 
      // select a video capture device 
      if (_capturectrl.VideoDevices["USB"] == null) 
         throw new Exception("No USB video device available"); 
 
      _capturectrl.VideoDevices["USB"].Selected = true; 
 
      // set a video compressor for the capture file 
      _capturectrl.VideoCompressors.Mpeg4.Selected = true; 
 
      // start the capture 
      _capturectrl.StartCapture(CaptureMode.Still); 
 
      // save the still DIB to a file 
      _capturectrl.SaveStillDIB(_dibFile, -1); 
 
      // stop the capture 
      _capturectrl.StopCapture(); 
 
      // check for the capture file and set the result 
      if (File.Exists(Path.Combine(Directory.GetCurrentDirectory(), _dibFile))) 
         _result = true; 
   } 
   catch (Exception) 
   { 
      _result = false; 
   }
