26-07-2004. Updated 04-04-2006: Compatible with MacOS X3 (X.3.8, X.3.9) and MacOS X4. ImageJ distribution 1.42 only.

This method works with the following settings : Java 1.4.2 update 2 (09/23/04)

! The MacOS 10.3.9 (15-04-2005) update sometime causes troubles on some computers: for example, sometimes, ImageJ isn't recognised by the finder. In that case, the script asks what application has to be used during the first use after updating. Choose ImageJ in the list. The further utilisations of the script shall work correctly. 

--MacOS X -+ - -- -----+ --------

Apple Script is a technology developped by Apple since several years to automatize finder repetitive tasks and to pilote scriptable applications. These properties are used in this present work to automatize the update of ImageJ.

• you can download the major Updates as the following forms:
  - double-clickable upgrades, with the original version of ImageJ (you have to reinstall your personal plugins and macros)

  - JAR file (you upgrade your ImageJ software, keeping all your settings and personalized functionalities by updating the ij.jar file)

• download the regular update from ImageJ News by downloading the latest available ij.jar file.

If you have a customized version of ImageJ with your favorites plugins or macros, the upgrade by ij.jar file is more convenient.
You have to make it manually as explained in the "ImageJ documentation" at the chapter "MacOS X Installation".

How to proceede:

- Download the ImageJ Updater application (end of page).
- Download a JAR file from one of the two links shown above.
- To make the upgrade, just drop the ij.jar file onto the ImageJ Updater application.

- Option: if you have more than one ImageJ folder (i.e. more than one version) on your computer, you can choose the one you want to be updated. For that, just start the version to upgrade before using the ImageJ Updater application. The open ImageJ application will be taken into account for the upgrading process.

Here we have an example of a computer with two versions of ImageJ:

• The default version opened by OS X in this configuration is the one containend in the folder "ImageJ" (normally the latest used version). When the updater is used, the ij.jar file dropped is put in the "java" sub-repertory of the ImageJ application, and the old ij.jar is archived in a folder as you can see in the following screen shot.

• The use of the option allowing to choose a particular version to upgrade: in this example the ImageJ application contained in the folder called "imageJ 1.3.2" will be updated. For that, the ImageJ application is launched (following screen shot).

The picture below shows that the current version is 1.32j once ImageJ is charged. We want to upgrade it with the 1.33g ij.jar file.

After dropping the ij.jar file onto the ImageJ Updater application, the new version is 1.33g

The following picture shows the new archive folder of the old ij.jar file.

Note: avoid to run two ImageJ applications at the same time when you perform an upgrade. It might generate mistakes, if by inadvertency, the front ImageJ version is changed.
