ImageJA

ImageJA is a project that provides a clean Git History of the ImageJ 1.* branch, with a proper 'pom.xml' file so that it can be used with Maven without hassles.

Historical note

ImageJA used to be a fork of ImageJ, i.e. it was synchronized closely with ImageJ with a few changes on top:

• When run as an applet, ImageJA is embedded (slated to be _optionally_ embedded, once the maintainer finds some time to do it).
• The internal structure of ImageJA's recorder allows command listeners to get much more fine-grained information.
• When launching a text editor, in many cases ImageJA will now choose Fiji's Script Editor, if available, instead of the old AWT based ImageJ editor.
• ImageJA has an easy Plugin installer via Plugins>Install PlugIn... (ImageJ only has that drag-n-drop thingie).
• The instance listener is RMI-based with ImageJA, so there is no security issue with it.
• ImageJA's Command Launcher has fuzzy matching, too.
• A couple of bug fixes:
  • JavaScript in ImageJA can find plugin classes, too.
  • ImageJA also put back some not-yet-deprecated methods as deprecated.
  • A simple bug fix in PolygonRoi drawing (it moves to the first point, but then draws a line to the same first point rather than the second).
  • A little bug fix in StackWindow: if you have a 2D time lapse, ImageJ will still use the zSelector (rather than the tSelector).
  • ImageJA can handle https:// URLs, too.

Where is the applet used?

To the knowledge of the author of the advanced applet parts of ImageJA, the applet is used at least here:

• EMBL, for an internal web-based interface to a high-throughput system
• MPI-CBG, to display C.elegans databases
• In at least one commercial e-learning website.
