I found that too.

    $ echo P1 2 2 0 1 1 0 | pnmtops >/dev/null
    pnmtops: EOF / read error reading magic number

Using the latest netpbm.sf.net stable release, 10.11.5, gives

    $ echo P1 2 2 0 1 1 0 |
    > LD_LIBRARY_PATH=`pwd`/../lib ./pnmtops >/dev/null
    pnmtops: Error reading magic number from Netpbm image stream.  Most
    often, this means your input file is empty.

In *both* cases stdout does contain valid PostScript for the first
image, i.e.  the one `echoed'.

Using P2 doesn't show the problem, either with stock 9.14-2 or 10.11.5.

    $ echo P2 2 2 255 0 1 2 0 | pnmtops >/dev/null || echo fail
    $ 

    $ echo P2 2 2 255 0 1 2 0 |
    > LD_LIBRARY_PATH=`pwd`/../lib ./pnmtops >/dev/null ||
    > echo fail
    $ 

So that's probably the quick fix.  I'll email the maintainer about P1.

(What really sucks is the lack of man pages in the latest release,
despite them all existing in the past.)

Cheers,


Ralph.
