    5 NAME
    6        pdftopng  - Portable Document Format (PDF) to Portable Network Graphics
    7        (PNG) converter (version 4.02)
    8 
    9 SYNOPSIS
   10        pdftopng [options] PDF-file PNG-root
   11 
   12 DESCRIPTION
   13        Pdftopng converts  Portable  Document  Format  (PDF)  files  to  color,
   14        grayscale, or monochrome image files in Portable Network Graphics (PNG)
   15        format.
   16 
   17        Pdftopng reads the PDF file, PDF-file, and writes one PNG file for each
   18        page,  PNG-root-nnnnnn.png,  where  nnnnnn is the page number.  If PNG-
   19        root is '-', the image is sent to stdout (this is probably only  useful
   20        when converting a single page).
   21 
   22 CONFIGURATION FILE
   23        Pdftopng reads a configuration file at startup.  It first tries to find
   24        the user's private config file, ~/.xpdfrc.  If that doesn't  exist,  it
   25        looks  for  a  system-wide config file, typically /usr/local/etc/xpdfrc
   26        (but this location can be changed when pdftopng  is  built).   See  the
   27        xpdfrc(5) man page for details.
   28 
   29 OPTIONS
   30        Many  of  the following options can be set with configuration file com-
   31        mands.  These are listed in square brackets with the description of the
   32        corresponding command line option.
   33 
   34        -f number
   35               Specifies the first page to convert.
   36 
   37        -l number
   38               Specifies the last page to convert.
   39 
   40        -r number
   41               Specifies the resolution, in DPI.  The default is 150 DPI.
   42 
   43        -mono  Generate a monochrome image (instead of a color image).
   44 
   45        -gray  Generate a grayscale image (instead of a color image).
   46 
   47        -alpha Generate  an alpha channel in the PNG file.  This is only useful
   48               with PDF files that have been  constructed  with  a  transparent
   49               background.  The -alpha flag cannot be used with -mono.
   50 
   51        -freetype yes | no
   52               Enable  or  disable  FreeType  (a TrueType / Type 1 font raster-
   53               izer).  This defaults to "yes".  [config file: enableFreeType]
   54 
   55        -aa yes | no
   56               Enable or disable font anti-aliasing.  This defaults  to  "yes".
   57               [config file: antialias]
   58 
   59        -aaVector yes | no
   60               Enable or disable vector anti-aliasing.  This defaults to "yes".
   61               [config file: vectorAntialias]
   62 
   63        -opw password
   64               Specify the owner password for the  PDF  file.   Providing  this
   65               will bypass all security restrictions.
   66 
   67        -upw password
   68               Specify the user password for the PDF file.
   69

   71 
   72        -v     Print copyright and version information.
   73 
   74        -h     Print usage information.  (-help and --help are equivalent.)
   75
