NAME
pdftopng - Portable Document Format (PDF) to Portable Network Graphics
(PNG) converter (version 3.04)
SYNOPSIS
pdftopng [options] PDF-file PNG-root
DESCRIPTION
Pdftopng converts Portable Document Format (PDF) files to color,
grayscale, or monochrome image files in Portable Network Graphics (PNG)
format.
Pdftopng reads the PDF file, PDF-file, and writes one PNG file for each
page, PNG-root-nnnnnn.png, where nnnnnn is the page number. If PNG-
root is '-', the image is sent to stdout (this is probably only useful
when converting a single page).
CONFIGURATION FILE
Pdftopng 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 pdftopng is built). See the
xpdfrc(5) man page for details.
OPTIONS
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.
-mono Generate a monochrome image (instead of a color image).
-gray Generate a grayscale image (instead of a color image).
-freetype yes | no
Enable or disable FreeType (a TrueType / Type 1 font raster-
izer). This defaults to "yes". [config file: enableFreeType]
-aa yes | no
Enable or disable font anti-aliasing. This defaults to "yes".
[config file: antialias]
-aaVector yes | no
Enable or disable vector anti-aliasing. This defaults to "yes".
[config file: vectorAntialias]
-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.)
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.
