General

This is a template module for the ORFEO Toolbox(https://www.orfeo-toolbox.org/). It is designed to work with OTB >= 5.0 modular system. The module can be clone/copied in OTB/Module/Remote and compiled along with other OTB modules. However, it is also possible to build it as a standalone module.

This module is filled with a few templates to be used as a starting point for a module with actual content. It contains the templates for:

• a library (cxx source in src folder)
• headers and templated classes (include folder)
• a OTB Application (app folder)
• tests for C++ sources, applications and python wrappers (test folder)

This module also has its own continuous integration scripts (using Travis CI).

Getting Started

The official OTB Wiki documentation on adding an external module is here.

Remote Module

After a module has been created as a git repository it can be included as a remote module, which enables automatic fetching. Add a file in "OTB/Modules/Remote" called "YourModule.remote.cmake", for this module it would be "ExternalExample.remote.cmake" with the followlowing contents:

otb_fetch_module(ExternalTemplate
  "A template for a module."
  GIT_REPOSITORY https://github.com/orfeotoolbox/otbExternalModuleTemplate
  GIT_TAG master
  )

Editing

The files CMakeLists.txt and otb-module.cmake need to be modified with the name of the module, something along the following:

sed 's/ExternalTemplate/MyModule/g' CMakeLists.txt otb-module.cmake

There is the inplace option to sed, but it's not portable, so do this change by hand or look up the option in sed.

Then hack away at you code in include, src, test and app folders.

Continuous Integration

This module contains default files to enable Continuous Integration on Travis-CI:

• travis-ci.yml : this is the backbone of the CI process in Travis-CI, it defines the different jobs to run, and their environment
• ci.cmake : this CTest script drives the build and test process.
• vcvars_proxy.py : this script is used on Windows to export variables from vcvarsall.bat to the Git-Bash executor.

The README.md starts with a Travis-CI badge, you can change it to match your own module.

If you need to access data file from OTB/Data, you can tune the file ci.cmake which will download them for you before building:

• RM_GET_FULL_DATA: this flag will download all files under OTB/Data
• RM_DATA_PATTERNS: this variable allows to download only the files you need. Set this variable to a list of patterns (for instance Data/Input/QB_Toulouse_*.tif). This method should be faster.

It is a fork of the ITK template module provided by Bradley Lowekamp (https://github.com/blowekamp/itkExternalTemplate.git) which was adapted for the ORFEO ToolBox.
