SetModalityLut(DicomModalityLutAttributes,int[]) Method

Summary

Sets the attributes that describe the Modality LUT.

Syntax

Java

WinRT C#

C++

public void SetModalityLut( 
   DicomModalityLutAttributes attributes, 
   int[] data 
)

Public Overloads Sub SetModalityLut( _ 
   ByVal attributes As Leadtools.Dicom.DicomModalityLutAttributes, _ 
   ByVal data() As Integer _ 
)

public void SetModalityLut(  
   Leadtools.Dicom.DicomModalityLutAttributes attributes, 
   int[] data 
)

public void setModalityLut(DicomModalityLutAttributes attributes, int[]data)

 function Leadtools.Dicom.DicomDataSet.SetModalityLut(DicomModalityLutAttributes,Int32[])(  
   attributes , 
   data  
)

public: 
void SetModalityLut(  
   Leadtools.Dicom.DicomModalityLutAttributes^ attributes, 
   array<int>^ data 
)

Parameters

attributes
The Modality LUT attributes to set.

data
Array of integers that holds the "LUT Data".

Remarks

This method will set the attributes of the "Modality LUT Module". If you are trying to set the "Rescale Intercept" (0028,1052) and "Rescale Slope" (0028,1053), set IsRescaleSlopeIntercept to true, and populate RescaleIntercept and RescaleSlope with the new values. You can also populate RescaleType if you want to set "Rescale Type" (0028,1054).

If you are trying to set the elements under "Modality LUT Sequence", set IsModalityLutSequence to true, and populate FirstStoredPixelValueMapped, NumberOfEntries, EntryBits, and LutType. In this case, [data](" id="dataparameterlink" class="popuplink) should hold the "LUT Data" (0028,3006).

Example

This example will set the modality LUT information inside a DICOM dataset.
