Property Value

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

When the Leadtools.Codecs.RasterCodecs object finishes loading the image, the various properties of the RasterImage will be populated with the image information and data and the RasterImage.IsLoading property will be set to false.

It is recommended that you do not poll for the RasterImage.IsLoading property to check when the image is finished loaded, instead, subscribe to the RasterCodecs.LoadAsyncCompleted event to get notification on when the Leadtools.Codecs.RasterCodecs.LoadAsync(System.String,Leadtools.LeadRect,System.Int32,Leadtools.Codecs.CodecsLoadByteOrder,System.Int32,System.Int32,System.Object) operation is completed and if any errors occurred.

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

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
