Property Value

The RasterCodecs object supports getting information and loading image files asnchronously through the use of the RasterCodecs.GetInformationAsync and RasterCodecs.LoadAsync methods.

You can call one asyncronous operation per RasterCodecs object at a time. To check if the RasterCodecs object is busy with a previous asynchronous operation, use IsAsyncBusy property. This is the equivalant of the WebClient.IsBusy property of AsyncWebClient.

You can also use the CancelAsync method to cancel any current asynchronous operation in this RasterCodecs object. This is the equivalant of calling WebClient.CancelAsync on AsyncWebClient.

Note:UseAsync, AsyncWebClient, IsAsyncBusy, and CancelAsync are only applicable when the RasterCodecs.GetInformationAsync or RasterCodecs.LoadAsync was with the versions that take a System.Uri parameter. The versions thet take a System.String or a System.IO.Stream does not use a System.Net.WebClient object internally. If you want to check the progress or cancel the operation then use the LoadImage event as normal.

Target Platforms: Silverlight, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
