2012-05-18 - ImageJ v2.0.0-beta2

In keeping with the fine tradition of making a release on Friday afternoon, and immediately going on vacation, the ImageJDev team is pleased to release the second beta of ImageJ2, version 2.0.0-beta2!

ImageJ 2.0.0-beta2 is a “beta”-quality release, meaning the code is not finished. The design is more stable than before but still subject to change until the final 2.0.0 release. It is recommended that people continue to use ImageJ 1.x for critical work.

Download from the ImageJ2 development releases page.

The ImageJ2 user interface is modeled after ImageJ v1.x as much as possible. However, under the hood, ImageJ2 is a complete redesign of ImageJ. It provides backward compatibility with older versions of ImageJ by bundling the latest v1.x code and translating between “legacy” and “modern” image structures.

What’s new

The beta still has many bugs and limitations, but we have made some progress: ImageJ2 now has better support for headless image displays, and some critical bugs were also fixed. In particular, ImageJ2 should now work on Mac OS X 10.5 Leopard.

Known bugs

Many legacy ImageJ plugins and macros work; many others do not. There are still many bugs. In particular, there are a few issues specifically regarding 2.0.0-beta2:

  • On Windows & Linux, you must have Java already installed; ImageJ2 is not bundled with Java, nor will it download it for you.
  • Image windows do not always pack correctly, resulting in scroll bars.
  • [#1188] Also on Windows & Linux, the menu bar is sometimes unresponsive.
  • [#1190] Using a drawing tool on a panned or zoomed image does not draw in the right place.
  • [#1186] Zooming does not follow the mouse cursor properly.

We are hoping to fix most of the above issues for the next beta.

Roadmap and future directions

We make a substantial effort to document the work we are doing, and what needs to be done, to deliver a powerful and full-featured ImageJ2. All tasks are tracked by our Trac issue tracking system, which you can review in several ways:

You can also perform custom queries to further refine the results, if there are particular parts of the development that interest you.


Thanks for your interest in ImageJ2! Please give it a try, and feel free to report any bugs you find!
