.SH NAME
xpdfrc \- configuration file for Xpdf tools (version 3.02)
.SH DESCRIPTION
All of the Xpdf tools read a single configuration file.  If you have a
.I .xpdfrc
file in your home directory, it will be read.  Otherwise, a
system-wide configuration file will be read from
.IR /usr/local/etc/xpdfrc ,
if it exists.  (This is its default location; depending on build
options, it may be placed elsewhere.)  On Win32 systems, the
.I xpdfrc
file should be placed in the same directory as the executables.
.PP
The xpdfrc file consists of a series of configuration options, one
per line.  Blank lines and lines starting with a \'#' (comments) are
ignored.
.PP
The following sections list all of the configuration options, sorted
into functional groups.  There is an examples section at the end.
.SH INCLUDE FILES
.TP
.BI include " config\-file"
Includes the specified config file.  The effect of this is equivalent
to inserting the contents of
.I config\-file
directly into the parent config file in place of the
.I include
command.  Config files can be nested arbitrarily deeply.
.SH CHARACTER MAPPING
.TP
.BI nameToUnicode " map\-file"
Specifies a file with the mapping from character names to Unicode.
This is used to handle PDF fonts that have valid encodings but no
ToUnicode entry.  Each line of a nameToUnicode file looks like this:

.I "    " hex\-string name

The
.I hex\-string
is the Unicode (UCS-2) character index, and
.I name
is the corresponding character name.  Multiple nameToUnicode files can
be used; if a character name is given more than once, the code in the
last specified file is used.  There is a built-in default
nameToUnicode table with all of Adobe's standard character names.
.TP
.BI cidToUnicode " registry\-ordering map\-file"
Specifies the file with the mapping from character collection to
Unicode.  Each line of a cidToUnicode file represents one character:

.I "    " hex\-string

The
.I hex\-string
is the Unicode (UCS-2) index for that character.  The first line maps
CID 0, the second line CID 1, etc.  File size is determined by size of
the character collection.  Only one file is allowed per character
collection; the last specified file is used.  There are no built-in
cidToUnicode mappings.
.TP
.BI unicodeToUnicode " font\-name\-substring map\-file"
This is used to work around PDF fonts which have incorrect Unicode
information.  It specifies a file which maps from the given
(incorrect) Unicode indexes to the correct ones.  The mapping will be
used for any font whose name contains
.IR font\-name\-substring .
Each line of a unicodeToUnicode file represents one Unicode character:

.RI "    " in\-hex " " out\-hex1 " " out\-hex2 " ..."

The
.I in\-hex
field is an input (incorrect) Unicode index, and the rest of the
fields are one or more output (correct) Unicode indexes.  Each
occurrence of
.I in\-hex
will be converted to the specified output sequence.
.TP
.BI unicodeMap " encoding\-name map\-file"
Specifies the file with mapping from Unicode to
.IR encoding\-name .
These encodings are used for X display fonts and text output (see
below).  Each line of a unicodeMap file represents a range of one or
more Unicode characters which maps linearly to a range in the output
encoding:
.nf

.I "    " in\-start\-hex in\-end\-hex out\-start\-hex

.fi
Entries for single characters can be abbreviated to:
.nf

.I "    " in\-hex out\-hex

.fi
The
.I in\-start\-hex
and
.I in\-end\-hex
fields (or the single
.I in\-hex
field) specify the Unicode range.  The
.I out\-start\-hex
field (or the
.I out\-hex
field) specifies the start of the output encoding range.  The length
of the
.I out\-start\-hex
(or
.IR out\-hex )
string determines the length of the output characters (e.g., UTF-8
uses different numbers of bytes to represent characters in different
ranges).  Entries must be given in increasing Unicode order.  Only one
file is allowed per encoding; the last specified file is used.  The
.IR Latin1 ,
.IR ASCII7 ,
.IR Symbol ,
.IR ZapfDingbats ,
.IR UTF-8 ,
and
.I UCS-2
encodings are predefined.
.TP
.BI cMapDir " registry\-ordering dir"
Specifies a search directory,
.IR dir ,
for CMaps for the
.I registry\-ordering
character collection.  There can be multiple directories for a
particular collection.  There are no default CMap directories.
.TP
.BI toUnicodeDir " dir"
Specifies a search directory,
.IR dir ,
for ToUnicode CMaps.  There can be multiple ToUnicode directories.
There are no default ToUnicode directories.
.SH DISPLAY FONTS
.TP
.BI displayFontT1 " PDF\-font\-name T1\-file"
Maps a PDF font,
.IR PDF\-font\-name ,
to a Type 1 font for display.  The Type 1 font file,
.IR T1\-file ,
should be a standard .pfa or .pfb file.
.TP
.BI displayFontTT " PDF\-font\-name TT\-file"
Maps a PDF font,
.IR PDF\-font\-name ,
to a TrueType font for display.  The TrueType font file,
.IR TT\-file ,
should be a standard .ttf file.
.TP
.BI displayNamedCIDFontT1 " PDF\-font\-name T1\-file"
Maps a specific PDF CID (16-bit) font,
.IR PDF\-font\-name ,
to a CID font (16-bit PostScript font), for display.  There are no
default CID font mappings.
.TP
.BI displayCIDFontT1 " registry\-ordering T1\-file"
Maps the
.I registry\-ordering
character collection to a CID font (16-bit PostScript font), for
display.  This mapping is used if the font name doesn't match any of
the fonts declared with displayNamedCIDFont* commands.  There are no
default CID font mappings.
.TP
.BI displayNamedCIDFontTT " PDF\-font\-name TT\-file"
Maps a specific PDF CID (16-bit) font,
.IR PDF\-font\-name ,
to a (16-bit) TrueType font, for display.  There are no default CID
font mappings.
.TP
.BI displayCIDFontTT " registry\-ordering TT\-file"
Maps the
.I registry\-ordering
character collection to a (16-bit) TrueType font, for display.  This
mapping is used if the font name doesn't match any of the fonts
declared with displayNamedCIDFont* commands.  There are no default CID
font mappings.
.TP
.BI fontDir " dir"
Specifies a search directory for external font files.  There can be
multiple fontDir directories.  If a PDF file uses a font but doesn't
embed it, these directories will be searched for a matching font file.
These fonts are used by both xpdf (for display) and pdftops (for
embedding in the generated PostScript).  Type 1 fonts must have a
suffix of ".pfa", ".pfb", ".ps", or no suffix at all.  TrueType fonts
must have a ".ttf" suffix.  Other files in these directories will be
ignored.  There are no default fontDir directories.
.SH POSTSCRIPT CONTROL
.TP
.BI psPaperSize " width(pts) height(pts)"
Sets the paper size for PostScript output.  The
.I width
and
.I height
parameters give the paper size in PostScript points (1 point = 1/72
inch).
.TP
.BR psPaperSize " letter | legal | A4 | A3 | match"
Sets the paper size for PostScript output to a standard size.  The
default paper size is set when xpdf and pdftops are built, typically
to "letter" or "A4".  This can also be set to "match", which will set
the paper size to match the size specified in the PDF file.
.TP
.BR psImageableArea " llx lly urx ury"
Sets the imageable area for PostScript output.  The four integers are
the coordinates of the lower-left and upper-right corners of the
imageable region, specified in points (with the origin being the
lower-left corner of the paper).  This defaults to the full paper
size; the psPaperSize option will reset the imageable area
coordinates.
.TP
.BR psCrop " yes | no"
If set to "yes", PostScript output is cropped to the CropBox specified
in the PDF file; otherwise no cropping is done.  This defaults to
"yes".
.TP
.BR psExpandSmaller " yes | no"
If set to "yes", PDF pages smaller than the PostScript imageable area
are expanded to fill the imageable area.  Otherwise, no scalling is
done on smaller pages.  This defaults to "no".
.TP
.BR psShrinkLarger " yes | no"
If set to yes, PDF pages larger than the PostScript imageable area are
shrunk to fit the imageable area.  Otherwise, no scaling is done on
larger pages.  This defaults to "yes".
.TP
.BR psCenter " yes | no"
If set to yes, PDF pages smaller than the PostScript imageable area
(after any scaling) are centered in the imageable area.  Otherwise,
they are aligned at the lower-left corner of the imageable area.  This
defaults to "yes".
.TP
.BR psDuplex " yes | no"
If set to "yes", the generated PostScript will set the "Duplex"
pagedevice entry.  This tells duplex-capable printers to enable
duplexing.  This defaults to "no".
.TP
.BR psLevel " level1 | level1sep | level2 | level2sep | level3 | level3Sep"
Sets the PostScript level to generate.  This defaults to "level2".
.TP
.BI psFont " PDF\-font\-name PS\-font\-name"
When the
.I PDF\-font\-name
font is used in a PDF file, it will be translated to the PostScript
font
.IR PS\-font\-name ,
which is assumed to be resident in the printer.  Typically,
.I PDF\-font\-name
and
.I PS\-font\-name
are the same.  By default, only the Base-14 fonts are assumed to be
resident.
.TP
.BI psNamedFont16 " PDF\-font\-name wMode PS\-font\-name encoding"
When the 16-bit font
.I PDF\-font\-name
is used in a PDF file with the
.I wMode
writing mode and is not embedded, the
.I PS\-font\-name
font is substituted for it.  The writing mode must be either \'H' for
horizontal or \'V' for vertical.  The
.I PS\-font\-name
font is assumed to be resident in the printer and to use the specified
encoding (which must have been defined with the unicodeMap command).
.TP
.BI psFont16 " registry\-ordering wMode PS\-font\-name encoding"
When a 16-bit font using the
.I registry\-ordering
character collection and 
.I wMode
writing mode is not embedded and does not match any of the fonts
declared in psNamedFont16 commands, the
.I PS\-font\-name
font is substituted for it.  The writing mode must be either \'H' for
horizontal or \'V' for vertical.  The
.I PS\-font\-name
font is assumed to be resident in the printer and to use the specified
writing mode and encoding (which must have been defined with the
unicodeMap command).
.TP
.BR psEmbedType1Fonts " yes | no"
If set to "no", prevents embedding of Type 1 fonts in generated
PostScript.  This defaults to "yes".
.TP
.BR psEmbedTrueTypeFonts " yes | no"
If set to "no", prevents embedding of TrueType fonts in generated
PostScript.  This defaults to "yes".
.TP
.BR psEmbedCIDTrueTypeFonts " yes | no"
If set to "no", prevents embedding of CID TrueType fonts in generated
PostScript.  For Level 3 PostScript, this generates a CID font, for
lower levels it generates a non-CID composite font.
.TP
.BR psEmbedCIDPostScriptFonts " yes | no"
If set to "no", prevents embedding of CID PostScript fonts in
generated PostScript.  For Level 3 PostScript, this generates a CID
font, for lower levels it generates a non-CID composite font.
.TP
.BR psPreload " yes | no"
If set to "yes", PDF forms are converted to PS procedures, and image
data is preloaded.  This uses more memory in the PostScript
interpreter, but generates significantly smaller PS files in
situations where, e.g., the same image is drawn on every page of a
long document.  This defaults to "no".
.TP
.BR psOPI " yes | no"
If set to "yes", generates PostScript OPI comments for all images and
forms which have OPI information.  This option is only available if
the Xpdf tools were compiled with OPI support.  This defaults to "no".
.TP
.BR psASCIIHex " yes | no"
If set to "yes", the ASCIIHexEncode filter will be used instead of
ASCII85Encode for binary data.  This defaults to "no".
.TP
.BI psFile " file\-or\-command"
Sets the default PostScript file or print command for xpdf.  Commands
start with a \'|' character; anything else is a file.  If the file
name or command contains spaces it must be quoted.  This defaults to
unset, which tells xpdf to generate a name of the form <file>.ps for a
PDF file <file>.pdf.
.TP
.BI fontDir " dir"
See the description above, in the DISPLAY FONTS section.
.SH TEXT CONTROL
.TP
.BI textEncoding " encoding\-name"
Sets the encoding to use for text output.  (This can be overridden
with the "-enc" switch on the command line.)  The
.I encoding\-name
must be defined with the unicodeMap command (see above).  This
defaults to "Latin1".
.TP
.BR textEOL " unix | dos | mac"
Sets the end-of-line convention to use for text output.  The options
are:
.nf

    unix = LF
    dos  = CR+LF
    mac  = CR

.fi
(This can be overridden with the "-eol" switch on the command line.)
The default value is based on the OS where xpdf and pdftotext were
built.
.TP
.BR textPageBreaks " yes | no"
If set to "yes", text extraction will insert page breaks (form feed
characters) between pages.  This defaults to "yes".
.TP
.BR textKeepTinyChars " yes | no"
If set to "yes", text extraction will keep all characters.  If set to
"no", text extraction will discard tiny (smaller than 3 point)
characters after the first 50000 per page, avoiding extremely slow run
times for PDF files that use special fonts to do shading or
cross-hatching.  This defaults to "no".
.SH MISCELLANEOUS SETTINGS
.TP
.BR initialZoom " \fIpercentage\fR | page | width"
Sets the initial zoom factor.  A number specifies a zoom percentage,
where 100 means 72 dpi.  You may also specify \'page', to fit the page
to the window size, or \'width', to fit the page width to the window
width.
.TP
.BR continuousView " yes | no"
If set to "yes", xpdf will start in continuous view mode, i.e., with
one vertical screoll bar for the whole document.  This defaults to
"no".
.TP
.BR enableT1lib " yes | no"
Enables or disables use of t1lib (a Type 1 font rasterizer).  This is
only relevant if the Xpdf tools were built with t1lib support.
("enableT1lib" replaces the old "t1libControl" option.)  This option
defaults to "yes".
.TP
.BR enableFreeType " yes | no"
Enables or disables use of FreeType (a TrueType / Type 1 font
rasterizer).  This is only relevant if the Xpdf tools were built with
FreeType support.  ("enableFreeType" replaces the old
"freetypeControl" option.)  This option defaults to "yes".
.TP
.BR antialias " yes | no"
Enables or disables font anti-aliasing in the PDF rasterizer.  This
option affects all font rasterizers.  ("antialias" replaces the
anti-aliasing control provided by the old "t1libControl" and
"freetypeControl" options.)  This default to "yes".
.TP
.BR vectorAntialias " yes | no"
Enables or disables anti-aliasing of vector graphics in the PDF
rasterizer.  This defaults to "yes".
.TP
.BR strokeAdjust " yes | no"
Enables or disables stroke adjustment.  This defaults to "yes".
.TP
.BR screenType " dispersed | clustered | stochasticClustered"
Sets the halftone screen type, which will be used when generating a
monochrome (1-bit) bitmap.  The three options are dispersed-dot
dithering, clustered-dot dithering (with a round dot and 45-degree
screen angle), and stochastic clustered-dot dithering.  By default,
"stochasticClustered" is used for resolutions of 300 dpi and higher,
and "dispersed" is used for resolutions lower then 300 dpi.
.TP
.BI screenSize " integer"
Sets the size of the (square) halftone screen threshold matrix.  By
default, this is 4 for dispersed-dot dithering, 10 for clustered-dot
dithering, and 100 for stochastic clustered-dot dithering.
.TP
.BI screenDotRadius " integer"
Sets the halftone screen dot radius.  This is only used when
screenType is set to stochasticClustered, and it defaults to 2.  In
clustered-dot mode, the dot radius is half of the screen size.
Dispersed-dot dithering doesn't have a dot radius.
.TP
.BI screenGamma " float"
Sets the halftone screen gamma correction parameter.  Gamma values
greater than 1 make the output brighter; gamma values less than 1 make
it darker.  The default value is 1.
.TP
.BI screenBlackThreshold " float"
When halftoning, all values below this threshold are forced to solid
black.  This parameter is a floating point value between 0 (black) and
1 (white).  The default value is 0.
.TP
.BI screenWhiteThreshold " float"
When halftoning, all values above this threshold are forced to solid
white.  This parameter is a floating point value between 0 (black) and
1 (white).  The default value is 1.
.TP
.BI urlCommand " command"
Sets the command executed when you click on a URL link.  The string
"%s" will be replaced with the URL.  (See the example below.)  This
has no default value.
.TP
.BI movieCommand " command"
Sets the command executed when you click on a movie annotation.  The
string "%s" will be replaced with the movie file name.  This has no
default value.
.TP
.BI mapNumericCharNames " yes | no"
If set to "yes", the Xpdf tools will attempt to map various numeric
character names sometimes used in font subsets.  In some cases this
leads to usable text, and in other cases it leads to gibberish --
there is no way for Xpdf to tell.  This defaults to "yes".
.TP
.BI mapUnknownCharNames " yes | no"
If set to "yes", and mapNumericCharNames is set to "no", the Xpdf
tools will apply a simple pass-through mapping (Unicode index =
character code) for all unrecognized glyph names.  In some cases, this
leads to usable text, and in other cases it leads to gibberish --
there is no way for Xpdf to tell.  This defaults to "no".
.TP
.BI bind " modifiers-key context command ..."
Add a key or mouse button binding.
.I Modifiers
can be zero or more of:
.nf

    shift-
    ctrl-
    alt-

.fi
.I Key
can be a regular ASCII character, or any one of:
.nf

    space
    tab
    return
    enter
    backspace
    insert
    delete
    home
    end
    pgup
    pgdn
    left / right / up / down        (arrow keys)
    f1 .. f35                       (function keys)
    mousePress1 .. mousePress7      (mouse buttons)
    mouseRelease1 .. mouseRelease7  (mouse buttons)

.fi
.I Context
is either "any" or a comma-separated combination of:
.nf

    fullScreen / window       (full screen mode on/off)
    continuous / singlePage   (continuous mode on/off)
    overLink / offLink        (mouse over link or not)
    scrLockOn / scrLockOff    (scroll lock on/off)

.fi
The context string can include only one of each pair in the above
list.

.I Command
is an Xpdf command (see the COMMANDS section of the
.BR xpdf (1)
man page for details).  Multiple commands are separated by whitespace.

The bind command replaces any existing binding, but only if it was
defined for the exact same modifiers, key, and context.  All tokens
(modifiers, key, context, commands) are case-sensitive.

Example key bindings:
.nf

    # bind ctrl-a in any context to the nextPage
    # command
    bind ctrl-a any nextPage

    # bind uppercase B, when in continuous mode
    # with scroll lock on, to the reload command
    # followed by the prevPage command
    bind B continuous,scrLockOn reload prevPage

.fi
See the
.BR xpdf (1)
man page for more examples.
.TP
.BI unbind " modifiers-key context"
Removes a key binding established with the bind command.  This is most
useful to remove default key bindings before establishing new ones
(e.g., if the default key binding is given for "any" context, and you
want to create new key bindings for multiple contexts).
.TP
.BI printCommands " yes | no"
If set to "yes", drawing commands are printed as they're executed
(useful for debugging).  This defaults to "no".
.TP
.BI errQuiet " yes | no"
If set to "yes", this suppresses all error and warning messages from
all of the Xpdf tools.  This defaults to "no".
