Documentation about SciJava converters and SciJava ConvertService

[joheras]

Hi,

we recently released a new version of IJ-OpenCV (
https://github.com/joheras/IJ-OpenCV): a library with the aim of connecting
ImageJ and OpenCV. In that development, we built our converters on top of
SciJava converters, and used them to implement several ImageJ plugins.

Currently, and following the advice of Curtis Rueden (
https://github.com/joheras/IJ-OpenCV/issues/5), we are trying to
reimplement our plugins using SciJava commands to gain the advantages of
SciJava parametrized modules. To achieve this aim, I think that I need to
refactor my development.

I have found two projects where they are using SciJava converters and the
SciJava ConvertService to connect ImageJ with other systems:

   - ImageJ-Matlab (https://github.com/imagej/imagej-matlab) connecting
   ImageJ and Matlab, and
   - ImageJ-ITK (https://github.com/imagej/imagej-itk) connecting ImageJ
   and ITK.

However, I am not sure about the procedure that has been followed when
developing those libraries. Up to now what I have understood is that the
following steps are necessary:

1) Define an interface that extends the ImageJService with two methods:

   - Mat getMat(Dataset dataset):  to convert a Dataset to an OpenCV image.
   - Dataset getDataset(Mat mat): to conver an OpenCV image to a Dataset.

2) Implement the above interface with a class defined as a Service plugin.

3) Define the converter plugins using the above class.

Then, everything should be ready to take advantage of SciJava parametrized
modules, am I going in the right direction?

Could you indicate me any documentation that I could follow to implement
this functionality?

Thanks in advance.

Hi Jónathan,

Excited to see you working on this. However, in this case, you might get a
better response on the ImageJ Forum (http://forum.imagej.net/), and/or on
the Gitter channels (https://imagej.net/Chat), since you are asking about
very developer-centric things.

I am sorry I have not had time to reply in depth to your questions, but I
am rather overwhelmed right now. There are quite a few people on the forum
familiar with the SciJava development paradigm though, and you all can
always @mention me if you really need my advice specifically.

Regards,
Curtis

Thanks, I will contact the ImageJ forum.
