Syntax

C++/CLI

Java

public void SetWindow( 
   int index, 
   DicomWindowAttributes attributes 
)

public void setWindow(int index, DicomWindowAttributes attributes)

public: 
void SetWindow(  
   int index, 
   DicomWindowAttributes^ attributes 
)

Parameters

index
The zero-based index of the window center, window width value, to update. According to the DICOM standard, if multiple values are present for the window center and window width, both attributes shall have the same number of values and shall be considered as pairs.

attributes
The window-related attributes to set.

Remarks

This method will set the attributes that describe window center and window width.

If "Window Center" (0028,1050) does not already exist in the Data Set, this method will insert it and set its value to WindowCenter.

If "Window Width" (0028,1051) does not already exist in the Data Set, this method will insert it and set its value to WindowWidth.

Example

using Leadtools.Dicom;

{ 
   string dicomFileName = Path.Combine(LEAD_VARS.ImagesDir, "DICOM", "image3.dcm");

   //In the whole application 
   DicomEngine.Startup(); 
   using (DicomDataSet ds = new DicomDataSet())

      //Load DICOM File 
      ds.Load(dicomFileName, DicomDataSetLoadFlags.None); 
 
      int bitsStored = 16; 
      bool add = false;//Add a new window or replace the existing one(s) 
      int windowIndex = 0; 
      DicomWindowAttributes windowAttributes = new DicomWindowAttributes(); 
      if (ds.GetWindowCount(0) > 0)
