Public Sub RemapIntensityCommandBitmapEffectExample(ByVal element As FrameworkElement)
   Dim effect As RemapIntensityCommandBitmapEffect = New RemapIntensityCommandBitmapEffect()
   Dim LookupTable As Integer() = New Integer(255) {} ' Array to hold lookup table.

   'Get Lookup table where the array calculated by the linear function for all the items of the array is from 0 - 255.
   Dim value As Integer = 0
   For i As Integer = 255 To 0 Step -1
      LookupTable(i) = value
      value = value + 1
   Next i
   effect.Flags = RemapIntensityCommandBitmapEffectsFlags.Master

Remarks

  • This command supports signed data images.
  • The image intensity level range depends on the resolution of the image. For 64-bit, 48-bit, and 16-bit images, the intensity levels range from 0 to 2^16-1. For 12-bit images, the intensity levels range from 0 to 2^12-1. For other resolutions, the intensity levels range from 0 to 255.
  • Be sure that LookupTable property contains the number of the image intensity levels. For example if the image is 16-bit (the maximum image intensity level is 2^16 - 1).
  • This command supports signed data images.
  • This command does not support 32-bit grayscale images.
