Thanks Kees,
this was of course a typo in my mail.
It doesn't change the problem!
Thanks

Hi Herbie,
It should be:
run("Images to Stack","name=Seeds title=#");
setBatchMode(false);
exit();

Dear Jeremy,
dear listers!
Attached please find my macro with the mechanism suggested by Jeremy!
Interestingly, I wasn't able to make it work properly with
run("Images to Stack","name=Seeds title=#");
setBatchMode(true);
exit();
instead of
setBatchMode("exit and display");
run("Images to Stack","name=Seeds title=#");
exit();
In the former case, all slices are magically doubled.
Regards
Herbie

A slightly simpler variant on Herbie's macro.
Once you have a selection for single objects, use "Fit Rectangle" and then
duplicate.
The duplicated part of the image is rotated.

Subject: Re: can't rotate pasted image
Slightly off-topic William!
Some years ago I was asked to write a macro that performs this task on rice
seeds.
Attached please find the "revived" macro-code and a test-image.
The macro requires two ImageJ-plugins.
Good to hear you resolved the Java-problem.
Regards
Herbie

I'm writing code in java. What I am trying to do is take an image
with
20 wheat kernels in a petri dish and put each kernel in its own image
with the kernel rotated so all kernels are roughly vertical. Here's
the code snippet where I am doing it.
ImageProcessor newIp = new ColorProcessor(300, 300);
ImagePlus newImp = new ImagePlus("sub " + idx, newIp);
newIp.setColor(background);
newIp.fill();
imp.copy();
newImp.paste();
newImp.getProcessor().rotate(angle[idx]);
newImp.updateAndDraw();
newImp.show();
Previously, I've cut the subimage out of the original image using the
bounding box from analyze particles. The weirdness occurs somewhere
between the paste and the rotate. The pasting works whether I do the rotate or
not.
But when I paste, the rotate does not work. And, if I don't paste,
the rotate does work (I can tell this because the background is
tilted after a rotate with no paste but not with rotate and paste).
This snippet shows one of the things that I've tried, the updateAndDraw(), but
nothing has worked.
Any ideas on what I'm doing wrong?
Thanks,
wjr.
