30 // .NAME vtkImageMapToWindowLevelColors2 - map the input image through a lookup table and window / level it
31 // .SECTION Description
32 // The vtkImageMapToWindowLevelColors2 filter will take an input image of any
33 // valid scalar type, and map the first component of the image through a
34 // lookup table. This resulting color will be modulated with value obtained
35 // by a window / level operation. The result is an image of type
36 // VTK_UNSIGNED_CHAR. If the lookup table is not set, or is set to NULL, then
37 // the input data will be passed through if it is already of type
38 // UNSIGNED_CHAR.
