Hi,

   I responded to Suran yesterday, but thought that others may want
the fix as well.

Hi Suran,

   I looked into the problem you were having with pbm2viff and have a fix
for you.  It was my fault (usually is).  When writing the format i thought
the spec said that the pbm identifier ie P1, P2, P3, P4, etc must come on
line by itself.  That the format must look something like:

P4
200 197

not:

P4 200 197

If you are interested in fixing the problem here is a fix that i have
done a fairly healthy, but not extensive, testing on the omron and sun
with your test file and a few of our own.  So i don't expect any problems,
but as always please let me know if you find any.  To fix the problem
you'll need to change the file $KHOROS_HOME/src/file_formats/Lib/pbm.c
at line 112 from:

        if (!fgets(line, LENGTH, file))
        {
           (void) fprintf(stderr,"read_pbm:  Error!  Unexpected end of \n\

to:
        if (fscanf(file," %2c", line) <= 0)
        {
           (void) fprintf(stderr,"read_pbm:  Error!  Unexpected end of \n\


Then re-install the file formats library ($KHOROS_HOME/src/file_formats/Lib)
and also the pbm2viff program itself which is located in:

	$KHOROS_HOME/src/file_formats/standards/pbm2viff

} 
} Thanks in advance.
} 
} rgds,
} Suran.

Anyway i apologize for any problems this may have caused and thanks
again for bring this bug to our attention.

                        thanks,
                             Mark

ps.  i'll cc: this to khoros-bugs so that it gets logged.  Also i'll respond
     with this fix to the khoros mailing list later today since other people
     will probably get hit by this.
