Creating a new task type¶
Creating a new task type requires only basic scripting knowledge. For example a custom Python script can be wrapped in a new task type.
As a starting point it can be helpful to checkout an existing example:
In the menu open.
This is an example task type that uses an image processing algorithm provided by the Itk Python library.
Select it and use.
This copies the task type’s source files to disk for viewing and editing.
There is a metadata.json file to specify for example the name and version of the task type.
Change the name of the new task type, for example to YourName.Itk.Gauss.
There is a interface.json file to specify the available inputs and outputs.
Add a new input, for example variance.
There is a content/script.py file. In addition to the calls to the image processing library, it contains typical boilerplate code to accept the XamFlow inputs and provide the outputs.
Change the CurvatureAnisotropicDiffusionImageFilter to DiscreteGaussianImageFilter, and call SetVariance.
Checkin New Task Type¶
Finally once the files are ready for a first test the task type can be created:
Use the menuto get the files into XamFlow as a new task type.
Checkin Task Type Version¶
After checking in the new task type, the files can be changed further, and a new version of the task type can be created:
Use the menu.
