NAME
xpdfrc - configuration file for Xpdf tools (version 3.02)

DESCRIPTION
All of the Xpdf tools read a single configuration file. If you have a
.xpdfrc file in your home directory, it will be read. Otherwise, a
system-wide configuration file will be read from /etc/xpdf/xpdfrc, if
it exists. (This is its default location; depending on build options,
it may be placed elsewhere.) On Win32 systems, the xpdfrc file should
be placed in the same directory as the executables.

The xpdfrc file consists of a series of configuration options, one per
line. Blank lines and lines starting with a '#' (comments) are ig-
nored.

The following sections list all of the configuration options, sorted
into functional groups. There is an examples section at the end.

Note that all settings are case-sensitive; in particular, boolean op-
tions are "yes" and "no" (rather than "Yes" or "No").

INCLUDE FILES
include config-file
Includes the specified config file. The effect of this is
equivalent to inserting the contents of config-file directly
into the parent config file in place of the include command.
Config files can be nested arbitrarily deeply.

CHARACTER MAPPING
nameToUnicode map-file
Specifies a file with the mapping from character names to Uni-
code. This is used to handle PDF fonts that have valid encod-
ings but no ToUnicode entry. Each line of a nameToUnicode file
looks like this:

hex-string name

The hex-string is the Unicode (UCS-2) character index, and 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.

cidToUnicode registry-ordering map-file
Specifies the file with the mapping from character collection to
Unicode. Each line of a cidToUnicode file represents one char-
acter:

hex-string

The 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.

unicodeToUnicode font-name-substring map-file
This is used to work around PDF fonts which have incorrect Uni-
code 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 font-name-sub-
string. Each line of a unicodeToUnicode file represents one
Unicode character:

in-hex out-hex1 out-hex2 ...

The in-hex field is an input (incorrect) Unicode index, and the
rest of the fields are one or more output (correct) Unicode in-
dexes. Each occurrence of in-hex will be converted to the spec-
ified output sequence.

unicodeMap encoding-name map-file
Specifies the file with mapping from Unicode to 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:

in-start-hex in-end-hex out-start-hex

Entries for single characters can be abbreviated to:

in-hex out-hex

The in-start-hex and in-end-hex fields (or the single in-hex
field) specify the Unicode range. The out-start-hex field (or
the out-hex field) specifies the start of the output encoding
range. The length of the out-start-hex (or out-hex) string de-
termines 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 Latin1, ASCII7, Symbol, ZapfDingbats, UTF-8, and
UCS-2 encodings are predefined.

cMapDir registry-ordering dir
Specifies a search directory, dir, for CMaps for the reg-
istry-ordering character collection. There can be multiple di-
rectories for a particular collection. There are no default
CMap directories.

toUnicodeDir dir
Specifies a search directory, dir, for ToUnicode CMaps. There
can be multiple ToUnicode directories. There are no default
ToUnicode directories.

DISPLAY FONTS
displayFontT1 PDF-font-name T1-file
Maps a PDF font, PDF-font-name, to a Type 1 font for display.
The Type 1 font file, T1-file, should be a standard .pfa or .pfb
file.

displayFontTT PDF-font-name TT-file
Maps a PDF font, PDF-font-name, to a TrueType font for display.
The TrueType font file, TT-file, should be a standard .ttf file.

displayNamedCIDFontT1 PDF-font-name T1-file
Maps a specific PDF CID (16-bit) font, PDF-font-name, to a CID
font (16-bit PostScript font), for display. There are no de-
fault CID font mappings.

displayCIDFontT1 registry-ordering T1-file
Maps the 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 dis-
playNamedCIDFont* commands. There are no default CID font map-
pings.

displayNamedCIDFontTT PDF-font-name TT-file
Maps a specific PDF CID (16-bit) font, PDF-font-name, to a
(16-bit) TrueType font, for display. There are no default CID
font mappings.

displayCIDFontTT registry-ordering TT-file
Maps the 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 displayNamed-
CIDFont* commands. There are no default CID font mappings.

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 dis-
play) 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 de-
fault fontDir directories.

POSTSCRIPT CONTROL
psPaperSize width(pts) height(pts)
Sets the paper size for PostScript output. The width and height
parameters give the paper size in PostScript points (1 point =
1/72 inch).

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.

psImageableArea llx lly urx ury
Sets the imageable area for PostScript output. The four inte-
gers are the coordinates of the lower-left and upper-right cor-
ners of the imageable region, specified in points (with the ori-
gin being the lower-left corner of the paper). This defaults to
the full paper size; the psPaperSize option will reset the im-
ageable area coordinates.

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".

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".

psShrinkLarger yes | no
If set to yes, PDF pages larger than the PostScript imageable
area are shrunk to fit the imageable area. Otherwise, no scal-
ing is done on larger pages. This defaults to "yes".

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 im-
ageable area. This defaults to "yes".

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".

psFont PDF-font-name PS-font-name
When the PDF-font-name font is used in a PDF file, it will be
translated to the PostScript font PS-font-name, which is assumed
to be resident in the printer. Typically, PDF-font-name and
PS-font-name are the same. By default, only the Base-14 fonts
are assumed to be resident.

psNamedFont16 PDF-font-name wMode PS-font-name encoding
When the 16-bit font PDF-font-name is used in a PDF file with
the wMode writing mode and is not embedded, the PS-font-name
font is substituted for it. The writing mode must be either 'H'
for horizontal or 'V' for vertical. The 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 com-
mand).

psFont16 registry-ordering wMode PS-font-name encoding
When a 16-bit font using the registry-ordering character collec-
tion and wMode writing mode is not embedded and does not match
any of the fonts declared in psNamedFont16 commands, the
PS-font-name font is substituted for it. The writing mode must
be either 'H' for horizontal or 'V' for vertical. The
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).

psEmbedType1Fonts yes | no
If set to "no", prevents embedding of Type 1 fonts in generated
PostScript. This defaults to "yes".

psEmbedTrueTypeFonts yes | no
If set to "no", prevents embedding of TrueType fonts in gener-
ated PostScript. This defaults to "yes".

psEmbedCIDTrueTypeFonts yes | no
If set to "no", prevents embedding of CID TrueType fonts in gen-
erated PostScript. For Level 3 PostScript, this generates a CID
font, for lower levels it generates a non-CID composite font.

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.

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 Post-
Script 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".

psOPI yes | no
If set to "yes", generates PostScript OPI comments for all im-
ages and forms which have OPI information. This option is only
available if the Xpdf tools were compiled with OPI support.
This defaults to "no".

psASCIIHex yes | no
If set to "yes", the ASCIIHexEncode filter will be used instead
of ASCII85Encode for binary data. This defaults to "no".

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.

fontDir dir
See the description above, in the DISPLAY FONTS section.

TEXT CONTROL
textEncoding encoding-name
Sets the encoding to use for text output. (This can be overrid-
den with the "-enc" switch on the command line.) The encod-
ing-name must be defined with the unicodeMap command (see
above). This defaults to "Latin1".

textEOL unix | dos | mac
Sets the end-of-line convention to use for text output. The op-
tions are:

unix = LF
dos = CR+LF
mac = CR

(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.

textPageBreaks yes | no
If set to "yes", text extraction will insert page breaks (form
feed characters) between pages. This defaults to "yes".

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 ex-
tremely slow run times for PDF files that use special fonts to
do shading or cross-hatching. This defaults to "no".

MISCELLANEOUS SETTINGS
initialZoom percentage | page | width | height
Sets the initial zoom factor. A number specifies a zoom per-
centage, where 100 means 72 dpi. You may also specify 'page',
to fit the page to the window size, 'width', to fit the page
width to the window width, or 'height', to fit the page height
to the window height.

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 de-
faults to "no".

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" op-
tion.) This option defaults to "yes".

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".

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".

vectorAntialias yes | no
Enables or disables anti-aliasing of vector graphics in the PDF
rasterizer. This defaults to "yes".

strokeAdjust yes | no
Enables or disables stroke adjustment. This defaults to "yes".

screenType dispersed | clustered | stochasticClustered
Sets the halftone screen type, which will be used when generat-
ing a monochrome (1-bit) bitmap. The three options are dis-
persed-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 reso-
lutions of 300 dpi and higher, and "dispersed" is used for reso-
lutions lower then 300 dpi.

screenSize integer
Sets the size of the (square) halftone screen threshold matrix.
By default, this is 4 for dispersed-dot dithering, 10 for clus-
tered-dot dithering, and 100 for stochastic clustered-dot
dithering.

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.

screenGamma float
Sets the halftone screen gamma correction parameter. Gamma val-
ues greater than 1 make the output brighter; gamma values less
than 1 make it darker. The default value is 1.

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.

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.

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 be-
low.) This has no default value.

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.

mapNumericCharNames yes | no
If set to "yes", the Xpdf tools will attempt to map various nu-
meric 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".

mapUnknownCharNames yes | no
If set to "yes", and mapNumericCharNames is set to "no", the
Xpdf tools will apply a simple pass-through mapping (Unicode in-
dex = 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".

bind modifiers-key context command ...
Add a key or mouse button binding. Modifiers can be zero or
more of:

shift-
ctrl-
alt-

Key can be a regular ASCII character, or any one of:

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)

Context is either "any" or a comma-separated combination of:

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)

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

Command is an Xpdf command (see the COMMANDS section of the
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:

# 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

See the xpdf(1) man page for more examples.

unbind modifiers-key context
Removes a key binding established with the bind command. This
is most useful to remove default key bindings before establish-
ing new ones (e.g., if the default key binding is given for
"any" context, and you want to create new key bindings for mul-
tiple contexts).

printCommands yes | no
If set to "yes", drawing commands are printed as they're exe-
cuted (useful for debugging). This defaults to "no".

errQuiet yes | no
If set to "yes", this suppresses all error and warning messages
from all of the Xpdf tools. This defaults to "no".
