Update functions:
On line internet ressources are now a standard componant of software. A tool describing the basis of this functionality for « macros » development has been realized [2]. From this, it became possible to develop some update functions for the LUT and macro library [3].
Above: free sofware progresses thanks to collective work. The macro language and the associated developements are regulary updated. The diagram describes the original method developed to keep macro ressources up to date.
In the same way, a new method has been introduced making each project upgradable. Below: once submitted and accepted by the NIH, a project can evolve with the described method, independently of the first version preserved on the ImageJ website.
