GetStillHDIB Method

Summary

Gets a device-independent bitmap (DIB).

Syntax

C++/CLI

public virtual IntPtr GetStillHDIB( 
   int timeOut 
)

public:  
   virtual System::IntPtr GetStillHDIB( 
      Int32 timeOut 
   )

Parameters

timeOut
A value containing the maximum time to wait for the image, in milliseconds.

Return Value

System.IntPtr

Remarks

If the method succeeds, the caller must free the returned HDIB by calling the GlobalFree method. If TimeOut is -1, the method's time-out interval never elapses. If the method fails, an error is raised. For more information, refer to the Error Codes.

Example

using Leadtools; 
using Leadtools.MediaFoundation; 
using LeadtoolsMediaFoundationExamples.Fixtures; 
 
 
public bool _result = false; 
public PlayCtrlForm _form = new PlayCtrlForm(); 
 
public void GetStillHDIBExample() 
{ 
   // reference the capture control 
   PlayCtrl playctrl = _form.PlayCtrl; 
 
   // input file for capture 
   string inFile = Path.Combine(LEAD_VARS.MediaDir, "PlayCtrl_Source.avi"); 
   playctrl.SourceFile = inFile; 
   Application.DoEvents(); // Refresh before attempting DIB capture 
   try 
   { 
      IntPtr dib = playctrl.GetStillHDIB(-1); 
      _result = true; 
      Marshal.FreeHGlobal(dib); 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
}
