To put that into context: we just met at the EuBIAS conference (Mark is a developer of OpenMole, a software facilitating grid computing). The question was how to call ImageJ1 macros in a headless manner. In principle, after calling net.imagej.DefaultLegacyService.preinit() (contained in ij-legacy.jar [*1*]) you can call IJ.runMacro(String) or IJ.runMacroFile(String) [sic!] to evaluate macros even in headless mode: the preinit() method will make sure that the headless mode is activated, which lets quite a few plugins run in headless mode. When chatting to you (how about Cc:ing your colleagues into this conversation?), it became clear that you will need support for OSGi and are willing to help us with that... Great! Thank you! It also became apparent that you will need to call ImageJ 1.x macros in a massively parallel way. So I promised that I will implement a function that lets you call ImageJ 1.x macros via the LegacyService that uses separate class loaders so that the ImageJ 1.x "instances" cannot interfere with each other. Hopefully I will be able to show you tangible code at most in a few weeks. Feel free to bug me if you do not hear any progress record from me in the next few days! In the longer run, you will want to run scripts and macros via the ScriptService of ImageJ2, but for that, I think we will need our "macro" recorder which is still a bit off in the future. Ciao, Johannes Footnote *1*: To be precise, "ij-legacy.jar" is my shortcut to "the artifact of the Maven project hosted on http://maven.imagej.net/ (releases are in content/repositories/releases/, snapshots in .../snapshots/) identified by the GA net.imagej:ij-legacy. Currently, the latest release version is 2.0.0-beta-7.3 while the snapshot version 2.0.0-SNAPSHOT is "released" continously by our trusty Jenkins. _______________________________________________ ImageJ-devel mailing list ImageJ-devel@imagej.net http://imagej.net/mailman/listinfo/imagej-devel
