Property Value

The RasterCodecs class supports getting information on image files asynchronously using the RasterCodecs.GetInformationAsync methods. When calling any of these methods, the caller thread will not be blocked and the method will return instantly with an instance CodecsImageInfo that is in a loading status (CodecsImageInfo.IsLoading set to true). You should not use the other properties of this object while the object is in loading status.

When the RasterCodecs object finishes getting the information on the file, the various properties of the CodecsImageInfo will be populated with the image file information and the CodecsImageInfo.IsLoading property will be set to false.

It is recommended that you do not poll for the CodecsImageInfo.IsLoading property to check when the image information has been collected, instead, subscribe to the RasterCodecs.GetInformationAsyncCompleted event to get notification on when the RasterCodecs.GetInformationAsync operation is completed and if any errors occurred.

The RasterCodecs.GetInformationAsyncCompleted event data will also contain the same object returned from RasterCodecs.GetInformationAsync so you do not have to keep the original object in your application.

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