Example
using Leadtools;
using Leadtools.Codecs;
using Leadtools.ImageProcessing;
using Leadtools.ImageProcessing.Color;
using Leadtools.Svg;
public void GetInformationAsyncCompletedExample()
{
string srcFileName = Path.Combine(LEAD_VARS.ImagesDir, "Image1.cmp");
Uri uri = new Uri(srcFileName);
RasterCodecs codecs = new RasterCodecs();
// Now get information about the file asynchronously
codecs.GetInformationAsyncCompleted += new EventHandler<CodecsGetInformationAsyncCompletedEventArgs>(GetInformationAsyncCompletedExample_GetInformationAsyncCompleted);
object imageInfoObject = codecs.GetInformationAsync(uri, true, 1, null);
// Notice that the returned imageInfoObject is a CodecsImageInfo with IsLoading set to true at this point
// The IsLoading will be false (and hence, the object will be usable) when the GetInformationAsyncCompleted
// fires.
}

// Unsubscribe to the event and dispose the RasterCodecs object
