Section: Visualization Toolkit Imaging Classes

# Usage

The vtkImageMapToWindowLevelColors filter will take an input image of any valid scalar type, and map the first component of the image through a lookup table. This resulting color will be modulated with value obtained by a window / level operation. The result is an image of type VTK_UNSIGNED_CHAR. If the lookup table is not set, or is set to NULL, then the input data will be passed through if it is already of type UNSIGNED_CHAR.

To create an instance of class vtkImageMapToWindowLevelColors, simply invoke its constructor as follows

      obj = vtkImageMapToWindowLevelColors

# Methods

The class vtkImageMapToWindowLevelColors has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, `obj` is an instance of the vtkImageMapToWindowLevelColors class.

- `string = obj.GetClassName ()`
- `int = obj.IsA (string name)`
- `vtkImageMapToWindowLevelColors = obj.NewInstance ()`
- `vtkImageMapToWindowLevelColors = obj.SafeDownCast (vtkObject o)`
- `obj.SetWindow (double )` - Set / Get the Window to use -> modulation will be performed on the color based on (S - (L - W/2))/W where S is the scalar value, L is the level and W is the window.
- `double = obj.GetWindow ()` - Set / Get the Window to use -> modulation will be performed on the color based on (S - (L - W/2))/W where S is the scalar value, L is the level and W is the window.
- `obj.SetLevel (double )` - Set / Get the Level to use -> modulation will be performed on the color based on (S - (L - W/2))/W where S is the scalar value, L is the level and W is the window.
- `double = obj.GetLevel ()` - Set / Get the Level to use -> modulation will be performed on the color based on (S - (L - W/2))/W where S is the scalar value, L is the level and W is the window.
