Install new LUT's?

Philip Ershler
I know it's possible to load custom LUT's for an image that is open  
in ImageJ. Is there anyway to "install" custom LUT's so that they  
will show up in the menu with the standard LUT's. I found the Lookup  
Table folder in NIH image very convenient.

Thanks, Phil

Download and expand the ZIP file at

      http://rsb.info.nih.gov/ij/download/luts/luts.zip

and you will have a Lookup Table folder containing more than 100 LUTs.
To open a LUT on the Mac, drag and drop it on the ImageJ icon. On
Windows, drag and drop it on the "ImageJ" window.

ImageJ does not currently have built in support for transparency.

Wayne,
     On OS X, you can go one step better. Double click on one of  
the .lut files. Of course the operating system will ask what  
application should it use to open these types of files. Once you  
specify ImageJ, then you can put the folder full of LUTS into the  
dock. If you click and hold on the folder in the dock, you get what  
amounts to a menu of LUTS from which you can chose the LUT you wish.  
It's just as convenient as if new LUTS were added to ImageJ's menu.

Thanks again for all your amazing work and unbelievable support on  
ImageJ,

Phil

reconstructing a 3D from projections

Pedro Ramos
In reply to this post by Wayne Rasband
Dear all,

When you have a stack containing a 3D object (a series of MR images, for
example) and you use

 Image > Stack > 3D projection

you get a stack of projections of the object, rotating around it in
intervals of certain decided degree. I would like to do just the opposite
function. Having an stack of projected images get a 3D object (sort of
reversed 3D projector plugin). I thought that what I needed was a
backprojection reconstruction plugin. So I tried the backprokection plugin
form Michel Abramoff, included in the bij plugin package would do that.
Somehow I got weird images what do not correspond to a 3D object. Maybe I am
using the plugin wrong or maybe this is not the plugin I need. Does anyone
now how to address this issue. Thanks

Pedro
