public sealed class DicomEngine @interface LTDicomEngine : NSObject // STATIC CLASS public class DicomEngine public ref class DicomEngine sealed To begin using the LEADTOOLS DICOM .NET Class Library, the user must initialize the data required by the library. The data is initialized by calling the Startup method.
Once the Startup method has been called, you can use the different features exposed by the library.
When the LEADTOOLS DICOM .NET Class Library is no longer to be used, the user must free the data associated with the library by calling Shutdown.
