There is a setRoi method in the ImageProcessor class (or ImagePlus?), and you can manually make a variety of Rois using the various Roi subclasses. For a totally non-geometric Roi, the wand tool works well.

Subject: How is ImageJ creating Roi's?
Hello,
I am working on an thermal images analysing-application (no ImageJ plugin).
The image is processed as ImagePlus object and displayed with "myImage.show()".
I have already implemented LUT, rotate and zoom but i wasn't able to get the different kinds of ROI to work.
The problem must be, that i have no ImageJ-toolbar, so the selected Roi can't be prompted the usual way.
I was looking at the ImageCanvas class but couldn't find out how ImageJ gets the selected Roi.
Maybe someone could give me a hint where to look!
Thanks in advance,
Maximilian Loy
