'Declaration

'Usage

instance.Load(stream, flags)

public virtual void Load( 
   Stream stream,
   DicomDataSetLoadFlags flags
)

public void load(ILeadStream stream, /*DicomDataSetLoadFlags*/ int flags)

 function Leadtools.Dicom.DicomDataSet.Load(Stream,DicomDataSetLoadFlags)( 
   stream ,
   flags 
)

public:
virtual void Load( 
   Stream^ stream,
   DicomDataSetLoadFlags flags
)

Parameters

stream: A stream contains the Data Set to be loaded.
flags: Meta-header flags and Transfer Syntax flags that indicate the file characteristics to use when loading the file.

If you know certain characteristics of the file, you can set those in flags. Any characteristic that you do not set will be automatically determined. For example, if you know that the Meta-header is present, but you do not know the byte order, or whether the Value Representation is Implicit or Explicit, you can set only DicomDataSetLoadFlags.MetaHeaderPresent in flags. During loading, LEADTOOLS will determine the byte order and whether the byte order is Implicit or Explicit.

If you do not know any of the characteristics of the file, set flags to DicomDataSetLoadFlags.None and LEADTOOLS will automatically determine all the file characteristics and load the file accordingly.

In this overload, the DicomDataSetLoadFlags.LoadAndClose is always used internally, even if not included in the flags

To load a Data Set from memory, you can also use DicomDataSet.Load(IntPtr, long, DicomDataSetFlags). To load a Data Set from a file, you can use DicomDataSet.Load(string, DicomDataSetLoadFlags).

This example will load a DICOM Dataset from a file, save to a stream, load from a stream, and save to another file.
