Python plugins

--------------

Set OTB environment

--------------------

export PYTHONPATH=/path/to/OTB/install/lib/otb/python/:$PYTHONPATH

# Environment variable for old OTB versions

export ITK_AUTOLOAD_PATH=/path/to/OTB/install/lib/otb/applications/

# Environment variable for new OTB versions

export OTB_APPLICATION_PATH=/path/to/OTB/install/lib/otb/applications/

# Set LD_LIBRARY_PATH

export LD_LIBRARY_PATH=/path/to/OTB/install/lib/:$LD_LIBRARY_PATH

Set QGIS environment

---------------------

export PYTHONPATH=:/usr/share/qgis/python/plugins:~/.qgis2/python/plugins:$PYTHONPATH

# Set LD_LIBRARY_PATH

export LD_LIBRARY_PATH=/path/to/QGIS/install/lib/:$LD_LIBRARY_PATH

# Add maintenance folder to python path

export PYTHONPATH=/path/to/QGIS/src/python/plugins/processing/algs/otb/maintenance:$PYTHONPATH

Check the white and black list for the current OTB version

----------------------------------------------------------

In the maintenance directory, the OTB applications are split in two files black_list.xml and white_list.xml.

These files are organized as follows :

For each OTB version, a new node version with id as attribute is added to the node data.

Each application is then added in the node app_name.

```xml

<?xml version="1.0"?>

<data>

<version id="3.16">

<app_name>BinaryMorphologicalOperation</app_name>

<app_name>EdgeExtraction</app_name>

<app_name>GrayScaleMorphologicalOperation</app_name>

<app_name>DimensionalityReduction</app_name>

<app_name>Pansharpening</app_name>

<app_name>ExtractROI</app_name>

<app_name>RigidTransformResample</app_name>

<app_name>Segmentation</app_name>

<app_name>KMeansClassification</app_name>

<app_name>TrainSVMImagesClassifier</app_name>

<app_name>ComputeConfusionMatrix</app_name>

<app_name>OpticalCalibration</app_name>

<app_name>SarRadiometricCalibration</app_name>

<app_name>Smoothing</app_name>

</version>

</data>

```

The list of available applications for each version is not fixed.

OTBSpecific_XMLcreation.py

--------------------------

Warning : Some of the applications needs to be split to be user-friendly. Here comes the file OTBSpecific_XMLcreation.py.

Each function follows the pattern getNameOfTheOTBApplication().
