public class AlphaLUTTransferFunction
extends AbstractDataElementWrapper
implements CodeStringWrapper

Name: Alpha LUT Transfer Function
Keyword: AlphaLUTTransferFunction
Tag: (0028,1410)
Value Representation: CS
Value Multiplicity: 1

• Described in the contexts:
  • MPR Volumetric Presentation State Display Module > Presentation State Classification Component Sequence > Alpha LUT Transfer Function
  as follows:
  Attribute Name: Alpha LUT Transfer Function
  Type: 1C
  Attribute Description:

  Specifies the transformation that is used to create the Alpha input a compositor component.

  Enumerated Values:

  NONE

  Output = 1 (opaque) for all input values

  IDENTITY

  Output = input value

  TABLE

  Output = output of the Alpha LUT

  Required if the number of Items in Presentation State Classification Component Sequence (0070,1801) is greater than 1.

  Note

  When this condition is true, there will be one or more compositor components to follow this classification component.

  
  
• Described in the contexts:
  • Enhanced Palette Color Lookup Table Module > Enhanced Palette Color Lookup Table Sequence > Alpha LUT Transfer Function
  as follows:
  Attribute Name: Alpha LUT Transfer Function
  Type: 1
  Attribute Description:

  Specifies the transformation that is used to create the Alpha input to the Blending LUTs.

  Note

  Depending on the values of Blending LUT 1 Transfer Function (0028,1405) and Blending LUT 2 Transfer Function (0028,140D) the Alpha LUT value may be ignored. It is recommended that IDENTITY be used if this is the case.

  Enumerated Values:

  NONE

  IDENTITY

• Described in the contexts:
  • Render Display Module > Volume Stream Sequence > Presentation State Classification Component Sequence > Alpha LUT Transfer Function
  as follows:
  Attribute Name: Alpha LUT Transfer Function
  Type: 1
  Attribute Description:

  Specifies the transformation that is used to create the Alpha input to a compositor component (if present) and the opacity value for use in the Volume Rendering compositor.

  Enumerated Values:

  NONE

  Output = 1 (opaque) for all input values.

  IDENTITY

  Output = input value.

  TABLE

  Output = output of the Alpha LUT.
