pdftopbm(1)pdftopbm(1)NAMEpdftopbm - Portable Document Format (PDF) to Portable
Bitmap (PBM) converter (version 2.02)
SYNOPSISpdftopbm [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.
