public class SampleTarget : System.IDisposable

'Declaration
 
Public Class SampleTarget 
   Implements System.IDisposable

'Usage
 
Dim instance As SampleTarget

public sealed class SampleTarget : IClosable //In WinRT the IDisposable interface is replaced by IClosable

function Leadtools.Multimedia.SampleTarget()

public ref class SampleTarget : public System.IDisposable

Remarks

A sample target will accept samples having a specific media type. This media type is set in the MediaType object. Once the media type is set, the media type for the sample target is set by calling the SampleTarget.SetAcceptedMediaType method. To determine the accepted media type of the sample target, call the SampleTarget.GetAcceptedMediaType method. The sample target object must be set to receive samples from either a CaptureCtrl object or a ConvertCtrl object and then start either the capture or the convert process. Once that is done, the sample target can begin receiving samples. Using the GetSample method, the sample target can get delivered samples one at a time, until the end of the stream is reached. When the end of the stream is reached, the convert or capture process should be stopped. For a more detailed description of this process, refer to Implementing a SampleTarget object.
