[ImageJ-devel] Scripts calling scripts with @Parameters

[Jan Eglinger]

Hi all,

how can I call a script using @Parameters (e.g. @ij.ImagePlus) from 
another script? Is this possible already?

I tried the following Javascript:

     // @ij.ImagePlus imp
     // @String name
     // @OUTPUT String result

     result = "Hello, " + name + ", the title is " + imp.getTitle();


and saved it into ./plugins/Print_Title.js
When I run it, the macro recorder records something like:

     IJ.run(imp, "Print Title", "imp=[img[blobs.gif (256x254x1x1x1)]] 
name=Jan");


When I now run this (Beanshell) script (with blobs.gif still open):

     import ij.IJ;

     imp = IJ.getImage();
     IJ.run(imp, "Print Title", "imp=[img[blobs.gif (256x254x1x1x1)]] 
name=Jan");

the String is initialized correctly, but `imp` seems to be `null`. 
(Leaving away the imp=.. yields an error "'imp' is required but unset.")

Is there a way to configure an ImagePlus (or Dataset or File) in this case?

Thx,
Jan
