.SH CONFIGURATION FILE
Pdfinfo 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 pdfinfo is built).  See the
.BR xpdfrc (5)
man page for details.
.SH 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.
.TP
.BI \-f " number"
Specifies the first page to examine.  If multiple pages are requested
using the "-f" and "-l" options, the size of each requested page (and,
optionally, the bounding boxes for each requested page) are printed.
Otherwise, only page one is examined.
.TP
.BI \-l " number"
Specifies the last page to examine.
.TP
.B \-box
Prints the page box bounding boxes: MediaBox, CropBox, BleedBox,
TrimBox, and ArtBox.
.TP
.B \-meta
Prints document-level metadata.  (This is the "Metadata" stream from
the PDF file's Catalog object.)
.TP
.BI \-enc " encoding-name"
Sets the encoding to use for text output.  The
.I encoding\-name
must be defined with the unicodeMap command (see
.BR xpdfrc (5)).
This defaults to "Latin1" (which is a built-in encoding).
.RB "[config file: " textEncoding ]
.TP
.BI \-opw " password"
Specify the owner password for the PDF file.  Providing this will
bypass all security restrictions.
.TP
.BI \-upw " password"
Specify the user password for the PDF file.
.TP
.BI \-cfg " config-file"
Read
.I config-file
in place of ~/.xpdfrc or the system-wide config file.
.TP
.B \-v
Print copyright and version information.
.TP
.B \-h
Print usage information.
.RB ( \-help
and
.B \-\-help
are equivalent.)
.SH EXIT CODES
The Xpdf tools use the following exit codes:
.TP
0

.TP
1
Error opening a PDF file.
.TP
2
Error opening an output file.
.TP
