ITK/Release 4/Wrapping

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

• 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

Languages

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

Topics

• gccxml maintenance

Brad working on it. Getting harder with newer compiler. Will probably possible for the next couple of years.

CLang must be explored as a replacement.

• migrating to WrapITK 0.3
• recode igenerator.py in C++

reuse cable code. already read gccxml output.

• languages support
  • keep python 2
  • keep java
  • add C#
  • add Python 3? maybe
  • remove Tcl? sure

• redefine the WrapITK libraries (grouping of classes)

use the same module organization than in ITK

• Default wrapped types and abbreviated naming scheme
• Wrapping coverage
• Binary distribution

distribute binary for now next move to ryppl

• ITK Image to/from target language array conversion
• Automatic Inline documentation
• Target language inheritance (SWIG directors)
• Automatic type selection in Python
• Improve 64bits support in ITK — surely done elsewhere already

remove 64 bit pixel type

rework filter using unsigned long type

• GDCM wrapping integration?

add interfaces in ITK classes and wrap those classes
