[ImageJ-devel] Bug in ImageJ2 ?

Thanks for the report. It's definitely a bug due to our recent refactoring
of the widget system. Both Boolean and boolean are supposed to work. I'll
look into fixing it today.

P.S. Hopefully I will have time to respond to your ImgLib mail from
yesterday, too. I really appreciate you taking the time to look at and
improve the Projector logic. We did the minimum necessary at the time to
get something working, but currently everything is planar, and there is no
built-in (i.e., ImgLib2) zoom capability, which we will eventually need.
