Hi Calem,<br><br><div><div>> Which IDE do you suggest?</div></div><div><br></div><div><div>We seriously want the project to work well in any Maven-enabled environment. So actually, it would be helpful for you to stick to your most preferred IDE, and report any issues you encounter.</div>
</div><div><br></div><div>That said, if you really want to know which tools the core developers use, the breakdown is roughly:</div><div><br></div><div><div>5x: Windows + Eclipse</div><div>1x: Windows + NetBeans</div><div>
2x: OS X + Eclipse</div><div>1x: OS X + Eclipse, vim, mvn</div><div>1x: OS X + NetBeans, Xcode</div><div>2x: Linux + Eclipse, vim, mvn</div><div><br></div></div><div>We have a dearth of IDEA users right now so you could use that just to cover all our bases. ;-)</div>
<div><br></div><div><div>> My primary goal write now is to quickly convert a MatLab project into</div><div>> an ImageJ Plug-in.</div><div><br></div><div>Presumably, your goal is to break the dependency on MATLAB? If not, and you just want to get the data into ImageJ by any means necessary, have you seen this?</div>
<div> <a href="http://fiji.sc/Miji">http://fiji.sc/Miji</a></div><div><br></div><div>If you need to cut MATLAB out of the picture, you could try a drop-in replacement such as JMathLib:</div><div> <a href="http://www.jmathlib.de/">http://www.jmathlib.de/</a></div>
<div><br></div><div>Either way, you will still need to write the ImageJ side of things, too.</div><div><br></div><div>> I believe I may move on to help develop the ImageJ core later on.</div><div><br></div><div>We would love for additional developers to get on board. With GitHub it is very easy to start contributing code upstream right away using Pull Requests.</div>
<div><br></div><div>> I imagine that you guys would prefer plug-ins were developed</div><div>> compatible to 2.0 as soon as possible, so I'd like to make the plug-in</div><div>> and design it for 2.0 (even if it isn't officially released).</div>
<div><br></div><div>Definitely; it will likely help you in the long term to develop for ImageJ2. You will pay a price in the short term since ImageJ2 is still in beta and you'll have to work harder to learn the system (less documentation, etc.). But we are more than happy to help and answer questions via the mailing list.</div>
<div><br></div><div>> Where would I find material on how to get started developing plugins</div><div>> for 2.0?</div></div><div><br></div><div><div>ImageJ2 supports several different kinds of plugins. You probably want a "command" which is a runnable operation that takes certain parameters as inputs, and produces others as outputs.</div>
<div><br></div></div><div>The web site has a brief discussion of commands here, with an example:</div><div> <a href="http://developer.imagej.net/extensibility">http://developer.imagej.net/extensibility</a></div><div><br>
</div><div>And check out the ImageJ2 Tutorials:</div><div> <a href="https://github.com/imagej/imagej-tutorials">https://github.com/imagej/imagej-tutorials</a></div><div><br></div><div>We plan to add many more tutorials over the next months as we prepare for the first 2.0.0 release.</div>
<div><br></div><div>You can also study the various commands present in the ij-commands-* projects. For example, check out ParameterTester (press Ctrl+Shift+T in Eclipse to quickly locate classes) for an illustration of the supported input types.</div>
<div><br></div><div>Lastly, we did an "ImageJ2 Plugins" workshop at the 2012 ImageJ Conference in Luxembourg last week. Those examples are currently posted at:</div><div> <a href="http://fiji.sc/ijconf/">http://fiji.sc/ijconf/</a></div>
<div><br></div><div>...and they will be committed to the Git repository soon.</div><div><br></div><div>Regards,</div><div>Curtis</div><div><br><br><div class="gmail_quote">On Wed, Oct 31, 2012 at 2:32 PM, Calem Bendell <span dir="ltr"><<a href="mailto:calembendell@live.com" target="_blank">calembendell@live.com</a>></span> wrote:<br>
