ImageJ 2.0.0-beta6 released

[ctrueden]

Hi everyone,

The ImageJDev team has released the sixth beta of ImageJ2, version 2.0.0-
beta6.

ImageJ 2.0.0-beta6 is a "beta"-quality release, meaning the code is not
finished. The design is more stable than before but still subject to change
until the final 2.0.0 release. It is recommended that people continue to
use ImageJ v1.x for critical work.

The ImageJ2 user interface is modeled after ImageJ v1.x as much as
possible. However, under the hood, ImageJ2 is a complete redesign of
ImageJ. It provides backward compatibility with older versions of ImageJ by
bundling the latest v1.x code and translating between "legacy" and "modern"
image structures.

Development of this release of ImageJ focused on improved legacy support.
In particular, ImageJ2 now allows you to switch to a dedicated "legacy
mode" for maximum compatibility with ImageJ1.

For further details on this release, including a discussion of new
features, please see our blog post:
  http://developer.imagej.net/2012/12/27/imagej-v200-beta6

You can download the release from:
  http://developer.imagej.net/downloads

To more accurately reflect what is left to do, we have again reestimated
ImageJ2's release dates, and scheduled additional betas before the final 2.0
.0 release. See the Downloads page for the updated table of planned future
releases and roadmap links for the project. The focus of the next release (
2.0.0-beta7) is on robust core support for N-dimensional data, including
very large image data, and data/display decoupling.

For more details on the ImageJ developments, see the web site at:
  http://developer.imagej.net/

Lastly, please note most of the ImageJ development team will be away for
the next 1-2 weeks, back in early January. So we may be a bit slow
responding to mails until then.

Hi Michael,

Thanks for the feedback regarding the ImageJ2 beta.

It will probably not be identical, but we are planning some improvements;
actually, the Brightness/Contrast window is the most common thing people
want improved. Relevant feature ticket is:

    http://trac.imagej.net/ticket/1100 ("Improve Brightness and Contrast
functionality")

I found this by going to trac.imagej.net, clicking View Tickets, selecting
"[Open Features]" and searching for "brightness" using the browser's Find
feature.

Note that the ticket also links to a couple of other sub-tickets in the
"Blocked By" field, all related to B&C.

I added your comments to the bottom of the ticket.

There actually is no ImageJ2 W&L command yet. The one included in
2.0.0-beta6 is the IJ1 version (which is why it has the IJ1 microscope
icon). Unfortunately, interactive IJ1 commands like that do not behave
properly in IJ2, so as you noted, the sliders do not work, and nothing
happens until the floating window is closed. The solution will be to
replace the W&L command with a pure IJ2 version, similar to the B&C
command. I filed a new ticket for that:

    http://trac.imagej.net/ticket/1613

I also CCed you on both tickets, so you'll be automatically updated when we
make progress. If you don't want that, let me know and I'll remove you.

Regards,
Curtis
