[ImageJ-devel] ImageJ2 scripting

[Mark Hiner]

Hi all,

>I would like to make things friendlier by automatically converting python
arrays to java, so I opened a new issue:
https://github.com/scijava/scripting-jython/issues/2

After further investigation, the problem wasn't type conversion but rather
that the createimg (and create) ops have a varargs parameter. Even though
an array was being passed, the individual values were being unwrapped (so
the Ops framework saw two parameters, instead of a single array parameter
with two elements).

The issue was not limited to jython scripting. I filed a PR to improve the
matching logic[1] - once it's merged, the following will all work:

   blank = ops.create(100, 50)

   blank = ops.create([100, 50])

   from jarray import array
   blank=ops.createimg(array([100, 50], 'l'))

Thanks again for the help and feedback!

Best,
Mark
