NAME
pdftopbm - Portable Document Format (PDF) to Portable
Bitmap (PBM) converter (version 2.02)
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) for
mat.
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 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.
- -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. Pro
viding 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 par
ticular, 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.
