[ImageJ-devel] plugin development for ImageJ2 or ImageJ1?

Thu Jan 8 08:29:17 CST 2015

Hi Gerrit,

>so given the fact that ImageJ2 reached the 2.0.0 stage in june last year,
and also since it is the default ImageJ version in Fiji

The ImageJ welcome page [1] describes each of Fiji, ImageJ 1.x and ImageJ2
in detail. But to clarify briefly, Fiji is a distribution of ImageJ - it
includes both ImageJ 1.x, and ImageJ2 (as well as a number of plugins).

>So from your message I conclude that although my customer uses Fiji, I
better stick to ImageJ1

Because Fiji ships both ImageJ 1.x and IJ2, it is capable of running
plugins for both. Since your client can use either, for production work
like it sounds you're doing, you should use the ImageJ 1.x API [2] due to
its stability. The ImageJ2 team is committed to backwards compatibility
with ImageJ 1.x [3], so your plugins should still work as ImageJ2 continues
to develop.

>Is there information available about ImageJ’s roadmap?

All our development happens on GitHub [4]. In particular, the base ImageJ
repository [5] provides a good view of issues and milestones.

>As you suggested I will send this message also to Imagej-devel, sorry for
cross-posting.

No worries at all. Per the mailing list descriptions [6], both of these
lists are perfectly appropriate for the scope of these discussions.

Hope this helps. Thanks for the questions - let us know if you have any
more!

Best,
Mark
