AllocTarget Method

Summary

Pre-allocates the capture target to the specified size.

Syntax

C++/CLI

public virtual void AllocTarget( 
   int size 
)

public: 
virtual void AllocTarget(  
   int size 
)

Parameters

size
Value containing the size of the target to be allocated, in megabytes.

Remarks

Pre-allocates the capture target to the specified size. This method is typically used when the target is defined as a file. For best capture results, always capture to a defragmented, pre-allocated capture file that is larger than the size of the capture data. If the method fails, an error is raised. For more information, refer to the Error Codes.

Example

using Leadtools; 
using Leadtools.Multimedia; 
using LeadtoolsMultimediaExamples.Fixtures; 
 
 
public bool _result = false; 
public CaptureCtrlForm _form = new CaptureCtrlForm(); 
string outFile = Path.Combine(LEAD_VARS.MediaDir, "CaptureCtrl_AllocTargetExample.avi"); 
 
public void AllocTargetExample() 
{ 
   // reference the capture control 
   CaptureCtrl capturectrl = _form.CaptureCtrl; 
 
   try 
   { 
      // set the target output file 
      capturectrl.TargetFile = outFile; 
 
      // allocate a file 
      capturectrl.AllocTarget(1000); 
 
      _result = File.Exists(outFile); 
   } 
   catch (COMException) 
   { 
      _result = false; 
   } 
   catch (Exception) 
   { 
      _result = false; 
   } 
} 
 
static class LEAD_VARS 
{ 
   public const string MediaDir = @"C:\LEADTOOLS23\Media";
