Changing the cursor image - How?

[Denny Hugg]

Working with photomicrographs of trematodes (Platyhelminthes: Digenea)  to
be measured at 4X to 40X. Running Linux Ubuntu 10.10 "Maverick Meerkat".
I've hunted the documentation and searched/scanned all directories, pounded
the Internet and can not find a reference or method of exchanging the
cursor image to one with crosshairs and a hollow (transparent) core. I've
built the image I want but can't discover where ImageJ 1.46e expects to
find it.

Can someone please advise of or direct to documentation describing the
location of the cursor image?

Code to change the cursor can be found here:
http://fiji.sc/MenuItemDiverter.java#l78

The problem is that the cursor in ImageJ is hardcoded:
fiji.sc/cgi-bin/gitweb.cgi?p=ImageJA.git;a=blob;f=src/main/java/ij/gui/ImageCanvas.java;h=78718c70335ecb770414c0ee4b9337177891617f;hb=refs/heads/master#l23

Sorry,
Johannes

The ImageJ 1.46f daily build, on startup, looks for a custom cursor image named "crosshair-cursor.gif" in the ImageJ/images folder. If found, ImageJ will use it instead of the standard crosshair cursor. There is an example custom cursor image at
