    @kephale
    oo @imagejan feel free to poke us about that

    @imagejan
    I will try to play with different logo versions on the weekend, and then ask you for opinions/improvements, @ctrueden @kephale
    Curtis Rueden
    @ctrueden
    Sounds good, thanks @imagejan.

    Uhm. Did ij-1.51v-SNAPSHOT.jar get on the ImageJ update site intentionally, @ctrueden?
    Jan Eglinger
    @imagejan
    :astonished: @stelfrich it is there, but my updater doesn't pick it up. Yours?
    Stefan Helfrich
    @stelfrich
    Mine did, this morning.. @imagejan
    Ignacio Arganda-Carreras
    @iarganda
    @imagejan mine too

    @imagejan
    That's strange, I still don't see it:

    @stelfrich It was not exactly intentional, but I needed to fix the ImageJA build.
    So I pushed imagej/ImageJA@fc5a1a4.
    I guess Upload-IJ1-into-ImageJ got triggered by the push, although I didn't realize that would happen.
    Stefan Helfrich
    @stelfrich
    Interesting
    Curtis Rueden
    @ctrueden
    I double checked, and indeed all pushes to master of ImageJA trigger that job. This makes sense when only release versions are pushed to that repo.
    Stefan Helfrich
    @stelfrich
    In that case, yes..
    Curtis Rueden
    @ctrueden
    @imagejan Is ij-1.51u.jar a shadow from an update site?
    Or are you behind a crazy network, like we were in Lisbon?
    Jan Eglinger
    @imagejan
    No, the updater says I get it from the ImageJ update site, and I also tried with a different Fiji installation on a different Windows computer.
    It's true I am behind a crazy network firewall, though...
    But usual updates work as expected, with a proxy configured in ImageJ
    Curtis Rueden
    @ctrueden
    @imagejan When you browse http://update.imagej.net/jars/ do you see the new 1.51v-SNAPSHOT artifact?
    Jan Eglinger
    @imagejan
    yes
    Curtis Rueden
    @ctrueden
    And at http://update.imagej.net/ you see db.xml.gz with "01-Mar-2018 11:04 66K "?
    (Not sure what Apache does for time zones, but it should certainly be March 1)
    Jan Eglinger
    @imagejan
    yes, also
    hm
    I'll try on yet another computer, just to make sure...
    Curtis Rueden
    @ctrueden
    The only time I've seen this problem was in Lisbon, when the local network was caching a very stale version of the db.xml.gz file.
    If you are running Java 1.8.0_101 or later, you could try changing http to https in your manage update site dialog.
    Jan Eglinger
    @imagejan
    That is strange: I saw the same thing (1.51u being reported as up-to-date) on two other machines (one Windows 7, one Mac OSX), the Mac installation even was at 1.51s still and got updated to 1.51u...
    Switching to https triggered the update to 1.51v-SNAPSHOT on my debugging installation running with Java-1.8.0_144
    The others a running with the bundled 1.8.0_66 I think, and I didn't test https there.
    Not that is would be important for me, but it's a conundrum indeed.
    Curtis Rueden
    @ctrueden
    Since the switch to HTTPS works, I expect the problem is similar to Lisbon: stale HTTP cache of the network. We will avoid it in future by migrating everything to HTTPS.

    @imagejan
    Is there a way to display an image with a specific color map in a Jupyter notebook? If yes, is there some example somewhere in imagej/tutorials?
    Curtis Rueden
    @ctrueden
    @imagejan With a Python notebook, or SJJK notebook? Or you don't care which?
    Jan Eglinger
    @imagejan

    Jan Eglinger
    @imagejan
    ??? My posts from mobile vanished?
    I said I have an SJJK notebook. But anything is fine to display an Img with color map.
    Curtis Rueden
    @ctrueden
    The display mechanism between Python and SJJK is fundamentally different.
    SJJK implements its own image output.
    Whereas with Python, you can use matplotlib or other libraries to show things.
    Philipp Hanslovsky
    @hanslovsky
    For python, there is matplotlib.pyplot.imshow. If you have shared memory images (or don't mind the copy) you could use that.
    Curtis Rueden
    @ctrueden
    Let me see about SJJK...
    Curtis Rueden
    @ctrueden
    @imagejan Unfortunately, it appears the image rendering in SJJK is not yet flexible enough to do custom color tables.
    The RAI must be converted to a BufferedImage in order to be displayed. This happens here.
    In theory, a Dataset could be converted differently/better, since Dataset can have custom color tables attached.
    Jan Eglinger
    @imagejan
    @ctrueden ok
    A possibility might be to have a function that takes the current ColorTable8 and convert into a 3-channel RAI first...
    Curtis Rueden
    @ctrueden
    However, at the moment, it does not do anything smart.
    You could use an ImgLib2 Converters utility method to massage the data into a multi-channel view.
