NAME
       pdftoppm  -  Portable  Document  Format  (PDF) to Portable
       Pixmap (PPM) converter (version 3.02)

SYNOPSIS
       pdftoppm [options] PDF-file PPM-root

DESCRIPTION
       Pdftoppm converts Portable Document Format (PDF) files  to
       color   image  files  in  Portable  Pixmap  (PPM)  format,
       grayscale image files in Portable Graymap (PGM) format, or
       monochrome image files in Portable Bitmap (PBM) format.

       Pdftoppm  reads the PDF file, PDF-file, and writes one PPM
       file for each page, PPM-root-nnnnnn.ppm, where  nnnnnn  is
       the page number.

CONFIGURATION FILE
       Pdftoppm  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 pdftoppm 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.

              Specifies the last page to convert.

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

       -mono  Generate a monochrome PBM file (instead of a  color
              PPM file).

              PPM file).

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