Wrapping

High-Level Goals

SIMPLIFY ITK by allowing easy access of the toolkit from other languages, especially scripting languages, hiding some difficulties (templates, compilation ...) along the way.

Metrics and goals

  • Avoid unnecessary dependencies (see Modular ITK)
  • FASTER
    • faster compilation
    • limited compilation ( see modular itk v4 )
    • faster re-compile (touching a given .h should not trigger a full re-compilation)
  • Wrap 80%+ of the toolkit
  • Have ITK behaves in the different languages as close to the native code as possible
    • ITK Image to/from target language array conversion
    • Target language inheritance (SWIG directors)
    • Automatic type selection in Python
  • Binary distribution
  • Automatic Inline documentation

Languages

  • Java
  • Python
  • Lua ?
  • Tcl ?
  • see simpleITK
