Summary

Represents the enumeration that determines the palette used to display the image.

Syntax

C#
VB
C++
public enum MedicalViewerPaletteType 
  
Public Enum MedicalViewerPaletteType  
   Inherits System.Enum 
   Implements System.IComparable, System.IConvertible, System.IFormattable  
             
            public enum class MedicalViewerPaletteType : public System.Enum, System.IComparable, System.IConvertible, System.IFormattable   
             

Members

ValueMemberDescription
0None None, use the normal gray-scale lookup table.
1Cool Cool palette.
2CyanHot Cyan Hot palette.
3Fire Fire palette.
4ICA2 ICA2 palette.
5Ice Ice palette.
6OrangeHot Orange hot palette.
7RainbowRGB Rainbow RGB palette.
8RedHot Red hot palette.
9Spectrum Spectrum palette.
Remarks
  • This enumeration is used with the property MedicalViewerSubCell.PaletteType
  • To disable using the palette, set this enumeration to None.
  • The palette works by replacing the gray intensity values stored in the image lookup table with the values stored in the palette.
