Thanks very much for the help with this, David. After I posted my
original query, I managed to get the second part of this task working
(writing the image to a file), after much trial and error. Your
suggestions were a big help with the first part.

I could not find anything containing "root" but this works:
IF (N_ELEMENTS(view) EQ 0) THEN view = 'VIEW_1' ;Default view to
rotate
data_space_id = itool_obj -> FindIdentifiers('*' + view + '*DATA
SPACE', /VISUALIZATION)
Is there a direct way to get an iTool object reference given the iTool
identifier? What I am doing now is:
previous_id = itGetCurrent()
ITCURRENT, itool_id
temp = itGetCurrent(TOOL = itool_obj)
At the end of the program I set the current iTool to previous
ITCURRENT, previous_id
When I feel brave in a few days, I think I'll post this code so that
everyone can point out the dumb ways I am doing things. This is a brave
new world for us unreconstructed Fortran programmers.

I don't think I'm ready for that yet. I'll save it for the advanced
course.
