xpdfrc.5

这是一个做pdf阅读器的源代码文件,是大家学习阅读器资料的很好参考

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".
