I would like to modify the cursor, under Java plugin control.

I have a particular plugin which allows the user to select particles.  We would like to modify the cursor so that it is a circle with a known size (in real world coordinates).

The plugin puts ImageJ into multi-point mode and allows the user to pick particles.  What we really want to do is to provide a quick and dirty size gauge so that the user can judge if this particle is BIG, or SMALL.

Is this possible?

If that can be done, the next level of ambition is to be able to modify the size of the circle under user control (perhaps some key presses).

In all cases, we would like the size of the circle-cursor to be in world coordinates, not pixels.  We currently drop markers on an overlay, keeping track of the size as the window’s magnification factor changes.  I’d like to do the same thing for the cursor.

All I can find is the ability to choose between an arrow and a crosshair-cursor.gif.
