OK; here it is:
Image "/tmp/l2h2225/p2252.pnm" is PPM, 47x49
Running "/usr/bin/pnmcrop -bot < /tmp/l2h2225/p2252.pnm > /tmp/l2h2225/p2252.t02"
pnmcrop: cropping 9 rows off the bottom
This 9 rows is too much for the 'shaving' logic.
It's expecting to remove only 1 or 2 lines.
(Perhaps something else is wrong too.)
So it keeps the unshaved /tmp/l2h2225/p2252.pnm for the final
image, rather than the shaved /tmp/l2h2225/p2252.t02 .
So a quick fix (i.e. hack) is to find where this logic is
encoded in pstoimg (it's just a Perl script).
Find where the test is done and increase the number of lines
allowed to be shaved.
Of course you cannot set an arbitrary number, else this will make
a real hash of $-$.
Give that a try, if you are prepared to make small edits
in the script.
Cheers,
Ross
