NAME
       pdftopbm  -  Portable  Document  Format  (PDF) to Portable
       Bitmap (PBM) converter (version 2.01)

SYNOPSIS
       pdftopbm [options] PDF-file PBM-root

DESCRIPTION
       Pdftopbm converts Portable Document Format (PDF) files  to
       black-and-white  image files in Portable Bitmap (PBM) for-
       mat.

       Pdftopbm reads the PDF file, PDF-file, and writes one  PBM
       file  for  each page, PBM-root-nnnnnn.pbm, where nnnnnn is
       the page number.

CONFIGURATION FILE
       Pdftopbm reads a configuration file at startup.  It  first
       tries  to  find the user's private config file, ~/.xpdfrc.
       If that doesn't exist, it looks for a  system-wide  config
       file,  typically  /usr/local/etc/xpdfrc (but this location
       can be changed when pdftopbm is built).  See the xpdfrc(5)
       man page for details.

OPTIONS
       Many  of  the following options can be set with configura-
       tion file commands.  These are listed in  square  brackets
       with  the  description  of  the corresponding command line
       option.

       -f number
              Specifies the first page to convert.

       -l number
              Specifies the last page to convert.

       -r number
              Specifies the resolution, in DPI.  The  default  is
              150 DPI.

       -opw password
              Specify  the owner password for the PDF file.  Pro-
              viding this will bypass all security  restrictions.

       -upw password
              Specify the user password for the PDF file.

       -q     Don't  print any messages or errors.  [config file:
              errQuiet]

       -v     Print copyright and version information.

       -h     Print usage information.   (-help  and  --help  are
              equivalent.)

BUGS
       Pdftopbm  uses  X to do the rendering, so it is limited by
       the capabilities and performance of the X server.  In par-
       ticular,  high-resolution  output requires lots of memory.
       Also, non-scalable fonts will not look great.

EXIT CODES
       The Xpdf tools use the following exit codes:

       0      No error.

       1      Error opening a PDF file.

       2      Error opening an output file.

       3      Error related to PDF permissions.

       99     Other error.
