Dear friends of ImageJ/Fiji scripting,
Just to let you know that you can now since the latest daily build version of ImageJ, directly loop over the roi in the Roi Manager without having to deal with the roi count and index
This concerns the scripting languages but unfortunately not the macro language (as far as I know).
The previous method is still usable, this new functionality wont break any existing code.
Here is a screencast from the related wiki section. Previous method a the top, new one below.
For the curious, see this PR for the changes to the source code.
