pdftopbm - Portable Document Format (PDF) to Portable Bitmap (PBM)
converter (version 2.03)
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 /usr/local/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 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.)
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.
The Xpdf tools use the following exit codes:
- No error.
- Error opening a PDF file.
- Error opening an output file.
- Error related
to PDF permissions.
- Other error.
