pdffonts(1)						      General Commands Manual						       pdffonts(1)

NAME

       pdffonts - Portable Document Format (PDF) font analyzer (version 2.01)

SYNOPSIS

       pdffonts [options] [PDF-file]

DESCRIPTION

       Pdffonts lists the fonts used in a Portable Document Format (PDF) file along with various information for each font.

       The following information is listed for each font:

       name   the font name, exactly as given in the PDF file (potentially including a subset prefix)

       type   the font type -- see below for details

       emb    "yes" if the font is embedded in the PDF file

       sub    "yes" if the font is a subset

       uni    "yes" if there is an explicit "ToUnicode" map in the PDF file (the absence of a ToUnicode map doesn't necessarily mean that the text
	      can't be converted to Unicode)

       object ID
	      the font dictionary object ID (number and generation)

       PDF files can contain the following types of fonts:

	      Type 1
	      Type 1C -- aka Compact Font Format (CFF)
	      Type 3
	      TrueType
	      CID Type 0 -- 16-bit font with no specified type
	      CID Type 0C -- 16-bit PostScript CFF font
	      CID TrueType -- 16-bit TrueType font

CONFIGURATION FILE

       Pdffonts 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 /etc/xpdfrc (but this location can be changed when pdffonts 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 analyze.

       -l number
	      Specifies the last page to analyze.

       -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.

       -cfg config-file
	      Read config-file in place of ~/.xpdfrc or the system-wide config file.

       -v     Print copyright and version information.

       -h     Print usage information.	(-help and --help are equivalent.)

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.
