       pdftopbm - Portable Document Format (PDF) to Portable Bitmap (PBM) con-
       verter (version 1.01)


       pdftopbm [options] PDF-file PBM-root


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

       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.


       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  /etc/xpdfrc  (but  this
       location can be changed when pdftopbm is built).  See the xpdfrc(5) man
       page for details.


       Many of the following options can be set with configuration  file  com-
       mands.  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.   Providing  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.)


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