Detailed Description

Widget for generating transfer functions via presets, threshold, and bell modes.

Provides a tabbed interface with three transfer function generation modes:

  • Presets: Load/save transfer function XML files and select named presets.
  • Threshold: Interactive threshold-based transfer function using crosshair drag.
  • Bell: Interactive bell-shaped (level/window) transfer function using crosshair drag.

The widget operates on the "TransferFunction" property of a mitk::DataNode.
