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) 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.

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 configuration 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. 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.)

BUGS
Pdftopbm uses X to do the rendering, so it is limited by the capabilities and performance of the X server. In particular, 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.
