Hi Kenneth,
What about setting 'attributes' to an image which is currently open to
transmit information?
imp.setProperty(java.lang.String key, java.lang.Object value)
then you can use a macro call to retrieve the value corresponding to the
key, from the same image while it remains open:
selectWindow("MyImage");
X = call("ImpProps.getProperty", "imageX");
where "imageX" is the key and X is the set/retrieved value

Hope it helps.

I write Java plugins. Most are self contained, and write results to files,
but I have a few PluginFilters which process images and produce a very tiny
amount of text or numerical output.
I’m looking for the cleanest way to make such output visible at the
macro-language level.
As a concrete example, I just produced a PlugInFilter which assumes a
particular class of image and “orients” it. It computes a rectangular
region with WIDTH, LENGTH, and ANGLE. As its last step, it rotates the
original image so that the rectangular region is aligned with the x- and
y-axes. It reports length, width, and angle in the log.
The customer wants to use the angle to rotate other images. He may
eventually want length and width as well. He is content to copy and paste
from the log, but I’d like to do better.
How can I best communicate these results, so the customer can use them in a
macro?
(Length, width, angle) look suspiciously like results from other commands,
and I’d be ok with that, but… More generally, is there a mechanism to make
visible a name-value pair which can be interrogated in the macro language?
