If you look at the documentation for the programs that do support stacks in
the netpbm package (pamsplit, pampick, pnmsplit, ...?), you will "Updated: 23
October 2005". So it looks like it is not a retired feature. As stated, I
find the feature useful.

I would not claim to know any "common methods" here. I simply have used
inline comments in the netpbm header to record things that I want to have
automatically associated with the file (camera exposure, date, data type,
various physical parameters of an experiment, etc.) without the need for me
to take the time to find the correct log book and search through it. It
stands to reason that if someone really wanted, they could have a set of
comment lines that looked like:
# boundingBox=a,b,c,d
and then just parse these comments. If you look at the PNM_Writer.java that I
sent, you will notice that I added a "# label : <label>" type of comment. I
had just this in mind, so that the PGM_Reader could set the slice label if it
found this comment. I just didn't implement it in the reader yet.
ciao,
Spencer
