Fixed a bug that did not close window with embedded macros when closing a project

version 0.98d 20-june-2010

The ".ojj" project file is now saved in compressed binary format, not xml. This is much faster and files are much smaller. It is still possible to export the project in the old xml format. Old projects still can be loaded, but older versions of ObjectJ will not recognize the newer binary format.

Project file now has an embedded macro set. With older versions, it was necessary to supply an accompanying macro file with the same base name. If older projects are opened, that external macro will automatically be recognized and embedded, i.e it will become part of the .ojj file when being saved.

Importing macro text currently only works only via menu "Show Embedded Macros" and Copy-Paste. The macro set will be installed and embedded via the button "Install under ObjectJ menu".

New menu Command ObjectJ> Project File> Save an Empty Copy allows to transfer macros, object definitions, column names etc to a new project.

Statistics in the results table can be shown by clicking on the leftmost column and selecting "Show all"

Thanks to Mateusz Kuzak, ObjectJ is now being tested on Linux.

version 0.96z --- 17-Sep-2009

In the "Objects" panel, changing item definitions such as "shape" or "marker type" could stop to accept further user input. Operation is now safe, though you may be asked to repeat the input.

version 0.96y --- 14-Sep-2009

In previous versions, the ObjectJ results table as well as the columns settings could stop to respond to user actions. This was a non-reproducible bug, which now hopefully is fixed due to synchronizing threads.

Fixed a cosmetic bug that appeared in OS X 10.5 (Leopard) and later, where buttons in the ObjectJ tools window lost their "Selected" appearance when e.g selecting an image window.

Fixed a bug that would not delete "All Objects in Current Image/Slice" when image was not shown at 100% zoom

Unqualified object numbers are better visible on any gray background

version 0.96x --- 23-Aug-2009

Thanks to Wayne Rasband, ImageJ 1.43f recognizes project files with the .ojj extension: opening a project file will automatically load the ObjectJ plugin. You now can drag an .ojj file onto ImageJ's microscope icon. Further, project files are double-clickable if you associate the ".ojj" extension to ImageJ (see Concept+Tips).

version 0.96u --- 03-Aug-2009

Drag and Drop of macros or images from a webbrowser to ImageJ window didn't work with ObjectJ. This is fixed.

--- 14-Jul-2009

Virus alerts: I removed all StatCounter code from this website. This was a script embedded into html code to count visitors. Unfortunately, some PC users complained about virus alerts, athough this is not a virus. If your computer still shows a virus alert, it is because the old content is still in the cache. The statcounter script was visible at the bottom of the "Home" or "Tutorial" html code. It is now removed.

Column names must be unique

fixed a bug that gave wrong mouse actions when no project was open
