00031 // .NAME vtkImageMapToWindowLevelColors2 - map the input image through a lookup table and window / level it
00032 // .SECTION Description
00033 // The vtkImageMapToWindowLevelColors2 filter will take an input image of any
00034 // valid scalar type, and map the first component of the image through a
00035 // lookup table.  This resulting color will be modulated with value obtained
00036 // by a window / level operation. The result is an image of type
00037 // VTK_UNSIGNED_CHAR. If the lookup table is not set, or is set to NULL, then
00038 // the input data will be passed through if it is already of type
00039 // UNSIGNED_CHAR.
