Load external plugin programmatically

[Thomas Lenoir]

Hello,

I'm currently writing an application to process .zvi files and I'd like to know how to load loci plugins
programmatically ?
I know where to place loci_tools.jar in order to view .zvi files with the ImageJ app, but I haven't found
anything on how to load external plugins from java.

Thanks.

Thomas

Hi Thomas,

You say your program is an "application." Does that mean it is a
standalone program? Or are you writing a plugin or macro for ImageJ?
If writing a macro,  you can use the Bio-Formats Macro Extensions. For
a plugin, you should be able to just import the appropriate
loci.formats.* classes in your plugin code as long as both
loci_tools.jar and your plugin are in the ImageJ plugins folder.

If your application is really standalone and does not depend on
ImageJ, then you can instead follow the directions on the Bio-Formats
web site at <http://www.loci.wisc.edu/ome/formats.html> for "Using
Bio-Formats as a library" without involving ImageJ at all (unless you
are making use of ImageJ's image processing capabilities elsewhere in
your app). In particular I suggest you take a look at the "Using
Bio-Formats Guide" available at
<https://skyking.microscopy.wisc.edu/svn/java/trunk/loci/formats/doc/using-bioformats.txt>
and linked from the web site.

Thanks for your help Curtis ! I'm in the standalone case and I've  
managed to display my .zvi images via an ImagePlusWrapper and it seems  
to work.

Hi Thomas,

Sure, that's one way to do it. But you can also just get BufferedImage
objects directly from an ImageReader and do whatever you want with
them. Java provides lots of functionality related to BufferedImages,
including the ability to paint them directly to a Graphics object, so
you should be able to use them in a variety of ways within your
application without using anything from the loci.plugins packages.

Actually, I really need all the stuff ImageJ offers, I'll mainly do  
image processing on these images.
Thanks again.
