86+.SH CONFIGURATION FILE
87+Pdffonts reads a configuration file at startup. It first tries to
88+find the user's private config file, ~/.xpdfrc. If that doesn't
89+exist, it looks for a system-wide config file, typically
90+/usr/local/etc/xpdfrc (but this location can be changed when pdffonts
91+is built). See the
92+.BR xpdfrc (5)
93+man page for details.
94+.SH OPTIONS
95+Many of the following options can be set with configuration file
96+commands. These are listed in square brackets with the description of
97+the corresponding command line option.
98+.TP
99+.BI \-f " number"
100+Specifies the first page to analyze.
101+.TP
102+.BI \-l " number"
103+Specifies the last page to analyze.
104+.TP
105+.BI \-opw " password"
106+Specify the owner password for the PDF file. Providing this will
107+bypass all security restrictions.
108+.TP
109+.BI \-upw " password"
110+Specify the user password for the PDF file.
111+.TP
112+.BI \-cfg " config-file"

170+.SH DESCRIPTION
171+.B Pdfimages
172+saves images from a Portable Document Format (PDF) file as Portable
173+Pixmap (PPM), Portable Bitmap (PBM), or JPEG files.
174+.PP
175+Pdfimages reads the PDF file, scans one or more pages,
176+.IR PDF-file ,
177+and writes one PPM, PBM, or JPEG file for each image,
178+.IR image-root - nnn . xxx ,
179+where
180+.I nnn
181+is the image number and
182+.I xxx
183+is the image type (.ppm, .pbm, .jpg).
184+.PP
185+NB: pdfimages extracts the raw image data from the PDF file, without
186+performing any additional transforms. Any rotation, clipping,
187+color inversion, etc. done by the PDF content stream is ignored.
188+.SH CONFIGURATION FILE
189+Pdfimages reads a configuration file at startup. It first tries to
190+find the user's private config file, ~/.xpdfrc. If that doesn't
191+exist, it looks for a system-wide config file, typically
192+/usr/local/etc/xpdfrc (but this location can be changed when pdfimages

208+Normally, all images are written as PBM (for monochrome images) or PPM
209+(for non-monochrome images) files. With this option, images in DCT
210+format are saved as JPEG files. All non-DCT images are saved in
211+PBM/PPM format as usual.

436+.SH SYNOPSIS
437+.B pdftoppm
438+[options]
439+.I PDF-file PPM-root
440+.SH DESCRIPTION
441+.B Pdftoppm
442+converts Portable Document Format (PDF) files to color image files in
443+Portable Pixmap (PPM) format, grayscale image files in Portable
444+Graymap (PGM) format, or monochrome image files in Portable Bitmap
445+(PBM) format.
446+.PP
447+Pdftoppm reads the PDF file,
448+.IR PDF-file ,
449+and writes one PPM file for each page,
450+.IR PPM-root - nnnnnn .ppm,
451+where
452+.I nnnnnn
453+is the page number.
454+.SH CONFIGURATION FILE
455+Pdftoppm reads a configuration file at startup. It first tries to
456+find the user's private config file, ~/.xpdfrc. If that doesn't
457+exist, it looks for a system-wide config file, typically
458+/usr/local/etc/xpdfrc (but this location can be changed when pdftoppm
459+is built). See the
460+.BR xpdfrc (5)
461+man page for details.
462+.SH OPTIONS
463+Many of the following options can be set with configuration file
464+commands. These are listed in square brackets with the description of
465+the corresponding command line option.

560+.SH SYNOPSIS
561+.B pdftops
562+[options]
563+.RI [ PDF-file
564+.RI [ PS-file ]]
565+.SH DESCRIPTION
566+.B Pdftops
567+converts Portable Document Format (PDF) files to PostScript so they
568+can be printed.
569+.PP
570+Pdftops reads the PDF file,
571+.IR PDF-file ,
572+and writes a PostScript file,
573+.IR PS-file .
574+If
575+.I PS-file
576+is not specified, pdftops converts
577+.I file.pdf
578+to
579+.I file.ps
580+(or
581+.I file.eps
582+with the -eps option). If
583+.I PS-file
584+is \'-', the PostScript is sent to stdout.
585+.SH CONFIGURATION FILE
586+Pdftops reads a configuration file at startup. It first tries to find
587+the user's private config file, ~/.xpdfrc. If that doesn't exist, it
588+looks for a system-wide config file, typically /usr/local/etc/xpdfrc
589+(but this location can be changed when pdftops is built). See the
590+.BR xpdfrc (5)
591+man page for details.
592+.SH OPTIONS
593+Many of the following options can be set with configuration file
594+commands. These are listed in square brackets with the description of
595+the corresponding command line option.
596+.TP
597+.BI \-f " number"
598+Specifies the first page to print.
599+.TP
600+.BI \-l " number"
601+Specifies the last page to print.
602+.TP
603+.B \-level1
604+Generate Level 1 PostScript. The resulting PostScript files will be
605+significantly larger (if they contain images), but will print on Level
606+1 printers. This also converts all images to black and white. No
607+more than one of the PostScript level options (-level1, -level1sep,
608+-level2, -level2sep, -level3, -level3Sep) may be given.
609+.RB "[config file: " psLevel ]
610+.TP
611+.B \-level1sep
612+Generate Level 1 separable PostScript. All colors are converted to
613+CMYK. Images are written with separate stream data for the four
614+components.
615+.RB "[config file: " psLevel ]
616+.TP
617+.B \-level2
618+Generate Level 2 PostScript. Level 2 supports color images and image
619+compression. This is the default setting.
620+.RB "[config file: " psLevel ]
621+.TP
622+.B \-level2sep
623+Generate Level 2 separable PostScript. All colors are converted to
624+CMYK. The PostScript separation convention operators are used to
625+handle custom (spot) colors.
626+.RB "[config file: " psLevel ]
627+.TP
628+.B \-level3
629+Generate Level 3 PostScript. This enables all Level 2 features plus
630+CID font embedding and masked image generation.
631+.RB "[config file: " psLevel ]
632+.TP
633+.B \-level3Sep
634+Generate Level 3 separable PostScript. The separation handling is the
635+same as for -level2Sep.
636+.RB "[config file: " psLevel ]
637+.TP
638+.B \-eps
639+Generate an Encapsulated PostScript (EPS) file. An EPS file contains
640+a single image, so if you use this option with a multi-page PDF file,
641+you must use -f and -l to specify a single page. No more than one of
642+the mode options (-eps, -form) may be given.
643+.TP
644+.B \-form
645+Generate a PostScript form which can be imported by software that
646+understands forms. A form contains a single page, so if you use this
647+option with a multi-page PDF file, you must use -f and -l to specify a
648+single page. The -level1 option cannot be used with -form.
649+.TP
650+.B \-opi
651+Generate OPI comments for all images and forms which have OPI
652+information. (This option is only available if pdftops was compiled
653+with OPI support.)
654+.RB "[config file: " psOPI ]
655+.TP
656+.B \-noembt1
657+By default, any Type 1 fonts which are embedded in the PDF file are
658+copied into the PostScript file. This option causes pdftops to
659+substitute base fonts instead. Embedded fonts make PostScript files
660+larger, but may be necessary for readable output.
661+.RB "[config file: " psEmbedType1Fonts ]
662+.TP
663+.B \-noembtt
664+By default, any TrueType fonts which are embedded in the PDF file are
665+copied into the PostScript file. This option causes pdftops to
666+substitute base fonts instead. Embedded fonts make PostScript files
667+larger, but may be necessary for readable output. Also, some
668+PostScript interpreters do not have TrueType rasterizers.
669+.RB "[config file: " psEmbedTrueTypeFonts ]
670+.TP
671+.B \-noembcidps
672+By default, any CID PostScript fonts which are embedded in the PDF
673+file are copied into the PostScript file. This option disables that
674+embedding. No attempt is made to substitute for non-embedded CID
675+PostScript fonts.
676+.RB "[config file: " psEmbedCIDPostScriptFonts ]
677+.TP
678+.B \-noembcidtt
679+By default, any CID TrueType fonts which are embedded in the PDF file
680+are copied into the PostScript file. This option disables that
681+embedding. No attempt is made to substitute for non-embedded CID
682+TrueType fonts.
683+.RB "[config file: " psEmbedCIDTrueTypeFonts ]
684+.TP
685+.B \-preload
686+Convert PDF forms to PS procedures, and preload image data. This uses
687+more memory in the PostScript interpreter, but generates significantly
688+smaller PS files in situations where, e.g., the same image is drawn on
689+every page of a long document.
690+.TP
691+.BI \-paper " size"
692+Set the paper size to one of "letter", "legal", "A4", or "A3". This
693+can also be set to "match", which will set the paper size to match the
694+size specified in the PDF file.
695+.RB "[config file: " psPaperSize ]
696+.TP
697+.BI \-paperw " size"
698+Set the paper width, in points.
699+.RB "[config file: " psPaperSize ]
700+.TP
701+.BI \-paperh " size"
702+Set the paper height, in points.
703+.RB "[config file: " psPaperSize ]
704+.TP
705+.B \-nocrop
706+By default, output is cropped to the CropBox specified in the PDF
707+file. This option disables cropping.
708+.RB "[config file: " psCrop ]
709+.TP
710+.B \-expand
711+Expand PDF pages smaller than the paper to fill the paper. By
712+default, these pages are not scaled.
713+.RB "[config file: " psExpandSmaller ]
714+.TP
715+.B \-noshrink
716+Don't scale PDF pages which are larger than the paper. By default,
717+pages larger than the paper are shrunk to fit.
718+.RB "[config file: " psShrinkLarger ]
719+.TP
720+.B \-nocenter
721+By default, PDF pages smaller than the paper (after any scaling) are
722+centered on the paper. This option causes them to be aligned to the
723+lower-left corner of the paper instead.
724+.RB "[config file: " psCenter ]
725+.TP
726+.B \-pagecrop
727+Treat the CropBox as the PDF page size. By default, the MediaBox is
728+used as the page size.
729+.TP
730+.B \-duplex
731+Set the Duplex pagedevice entry in the PostScript file. This tells
732+duplex-capable printers to enable duplexing.
733+.RB "[config file: " psDuplex ]

977+.SH CONFIGURATION FILE
978+Xpdf reads a configuration file at startup. It first tries to find
979+the user's private config file, ~/.xpdfrc. If that doesn't exist, it
980+looks for a system-wide config file, typically /usr/local/etc/xpdfrc
981+(but this location can be changed when xpdf is built). See the
982+.BR xpdfrc (5)
983+man page for details.
984+.SH OPTIONS
985+Many of the following options can be set with configuration file
986+commands or X resources. These are listed in square brackets with the
987+description of the corresponding command line option.

1740+.SH "REMOTE SERVER MODE"
1741+Xpdf can be started in remote server mode by specifying a server name
1742+(in addition to the file name and page number). For example:
1743+.PP
1744+.RS
1745+xpdf -remote myServer file.pdf
1746+.RE
1747+.PP
1748+If there is currently no xpdf running in server mode with the name
1749+\'myServer', a new xpdf window will be opened. If another command:
1750+.PP
1751+.RS
1752+xpdf -remote myServer another.pdf 9
1753+.RE
1754+.PP
1755+is issued, a new copy of xpdf will not be started. Instead, the first
1756+xpdf (the server) will load
1757+.I another.pdf
1758+and display page nine. If the file name is the same:
1759+.PP
1760+.RS
1761+xpdf -remote myServer another.pdf 4
1762+.RE
1763+.PP
1764+the xpdf server will simply display the specified page.
1765+.PP
1766+The -raise option tells the server to raise its window; it can be
1767+specified with or without a file name and page number.
1768+.PP
1769+The -quit option tells the server to close its window and exit.
1770+.SH EXIT CODES
1771+The Xpdf tools use the following exit codes:
1772+.TP
1773+0
1774+No error.
1775+.TP

1807+.SH NAME
1808+xpdfrc \- configuration file for Xpdf tools (version 3.02)
1809+.SH DESCRIPTION
1810+All of the Xpdf tools read a single configuration file. If you have a
1811+.I .xpdfrc
1812+file in your home directory, it will be read. Otherwise, a
1813+system-wide configuration file will be read from
1814+.IR /usr/local/etc/xpdfrc ,
1815+if it exists. (This is its default location; depending on build
1816+options, it may be placed elsewhere.) On Win32 systems, the
1817+.I xpdfrc
1818+file should be placed in the same directory as the executables.
1819+.PP
1820+The xpdfrc file consists of a series of configuration options, one
1821+per line. Blank lines and lines starting with a \'#' (comments) are
1822+ignored.
1823+.PP
1824+The following sections list all of the configuration options, sorted
1825+into functional groups. There is an examples section at the end.
1826+.SH INCLUDE FILES
1827+.TP
1828+.BI include " config\-file"
1829+Includes the specified config file. The effect of this is equivalent
1830+to inserting the contents of
1831+.I config\-file
1832+directly into the parent config file in place of the
1833+.I include
1834+command. Config files can be nested arbitrarily deeply.
1835+.SH CHARACTER MAPPING
1836+.TP
1837+.BI nameToUnicode " map\-file"
1838+Specifies a file with the mapping from character names to Unicode.
1839+This is used to handle PDF fonts that have valid encodings but no
1840+ToUnicode entry. Each line of a nameToUnicode file looks like this:
1841+
1842+.I " " hex\-string name
1843+
1844+The
1845+.I hex\-string
1846+is the Unicode (UCS-2) character index, and
1847+.I name
1848+is the corresponding character name. Multiple nameToUnicode files can
1849+be used; if a character name is given more than once, the code in the
1850+last specified file is used. There is a built-in default
1851+nameToUnicode table with all of Adobe's standard character names.
1852+.TP
1853+.BI cidToUnicode " registry\-ordering map\-file"
1854+Specifies the file with the mapping from character collection to
1855+Unicode. Each line of a cidToUnicode file represents one character:
1856+
1857+.I " " hex\-string
1858+
1859+The
1860+.I hex\-string
1861+is the Unicode (UCS-2) index for that character. The first line maps
1862+CID 0, the second line CID 1, etc. File size is determined by size of
1863+the character collection. Only one file is allowed per character
1864+collection; the last specified file is used. There are no built-in
1865+cidToUnicode mappings.
1866+.TP
1867+.BI unicodeToUnicode " font\-name\-substring map\-file"
1868+This is used to work around PDF fonts which have incorrect Unicode
1869+information. It specifies a file which maps from the given
1870+(incorrect) Unicode indexes to the correct ones. The mapping will be
1871+used for any font whose name contains
1872+.IR font\-name\-substring .
1873+Each line of a unicodeToUnicode file represents one Unicode character:
1874+
1875+.RI " " in\-hex " " out\-hex1 " " out\-hex2 " ..."
1876+
1877+The
1878+.I in\-hex
1879+field is an input (incorrect) Unicode index, and the rest of the
1880+fields are one or more output (correct) Unicode indexes. Each
1881+occurrence of
1882+.I in\-hex
1883+will be converted to the specified output sequence.
1884+.TP
1885+.BI unicodeMap " encoding\-name map\-file"
1886+Specifies the file with mapping from Unicode to
1887+.IR encoding\-name .
1888+These encodings are used for X display fonts and text output (see
1889+below). Each line of a unicodeMap file represents a range of one or
1890+more Unicode characters which maps linearly to a range in the output
1891+encoding:
1892+.nf
1893+
1894+.I " " in\-start\-hex in\-end\-hex out\-start\-hex
1895+
1896+.fi
1897+Entries for single characters can be abbreviated to:
1898+.nf
1899+
1900+.I " " in\-hex out\-hex
1901+
1902+.fi
1903+The
1904+.I in\-start\-hex
1905+and
1906+.I in\-end\-hex
1907+fields (or the single
1908+.I in\-hex
1909+field) specify the Unicode range. The
1910+.I out\-start\-hex
1911+field (or the
1912+.I out\-hex
1913+field) specifies the start of the output encoding range. The length
1914+of the
1915+.I out\-start\-hex
1916+(or
1917+.IR out\-hex )
1918+string determines the length of the output characters (e.g., UTF-8
1919+uses different numbers of bytes to represent characters in different
1920+ranges). Entries must be given in increasing Unicode order. Only one
1921+file is allowed per encoding; the last specified file is used. The
1922+.IR Latin1 ,
1923+.IR ASCII7 ,
1924+.IR Symbol ,
1925+.IR ZapfDingbats ,
1926+.IR UTF-8 ,
1927+and
1928+.I UCS-2
1929+encodings are predefined.
1930+.TP
1931+.BI cMapDir " registry\-ordering dir"
1932+Specifies a search directory,
1933+.IR dir ,
1934+for CMaps for the
1935+.I registry\-ordering
1936+character collection. There can be multiple directories for a
1937+particular collection. There are no default CMap directories.
1938+.TP
1939+.BI toUnicodeDir " dir"
1940+Specifies a search directory,
1941+.IR dir ,
1942+for ToUnicode CMaps. There can be multiple ToUnicode directories.
1943+There are no default ToUnicode directories.
1944+.SH DISPLAY FONTS
1945+.TP
1946+.BI displayFontT1 " PDF\-font\-name T1\-file"
1947+Maps a PDF font,
1948+.IR PDF\-font\-name ,
1949+to a Type 1 font for display. The Type 1 font file,
1950+.IR T1\-file ,
1951+should be a standard .pfa or .pfb file.
1952+.TP
1953+.BI displayFontTT " PDF\-font\-name TT\-file"
1954+Maps a PDF font,
1955+.IR PDF\-font\-name ,
1956+to a TrueType font for display. The TrueType font file,
1957+.IR TT\-file ,
1958+should be a standard .ttf file.
1959+.TP
1960+.BI displayNamedCIDFontT1 " PDF\-font\-name T1\-file"
1961+Maps a specific PDF CID (16-bit) font,
1962+.IR PDF\-font\-name ,
1963+to a CID font (16-bit PostScript font), for display. There are no
1964+default CID font mappings.
1965+.TP
1966+.BI displayCIDFontT1 " registry\-ordering T1\-file"
1967+Maps the
1968+.I registry\-ordering
1969+character collection to a CID font (16-bit PostScript font), for
1970+display. This mapping is used if the font name doesn't match any of
1971+the fonts declared with displayNamedCIDFont* commands. There are no
1972+default CID font mappings.
1973+.TP
1974+.BI displayNamedCIDFontTT " PDF\-font\-name TT\-file"
1975+Maps a specific PDF CID (16-bit) font,
1976+.IR PDF\-font\-name ,
1977+to a (16-bit) TrueType font, for display. There are no default CID
1978+font mappings.
1979+.TP
1980+.BI displayCIDFontTT " registry\-ordering TT\-file"
1981+Maps the
1982+.I registry\-ordering
1983+character collection to a (16-bit) TrueType font, for display. This
1984+mapping is used if the font name doesn't match any of the fonts
1985+declared with displayNamedCIDFont* commands. There are no default CID
1986+font mappings.
1987+.TP
1988+.BI fontDir " dir"
1989+Specifies a search directory for external font files. There can be
1990+multiple fontDir directories. If a PDF file uses a font but doesn't
1991+embed it, these directories will be searched for a matching font file.
1992+These fonts are used by both xpdf (for display) and pdftops (for
1993+embedding in the generated PostScript). Type 1 fonts must have a
1994+suffix of ".pfa", ".pfb", ".ps", or no suffix at all. TrueType fonts
1995+must have a ".ttf" suffix. Other files in these directories will be
1996+ignored. There are no default fontDir directories.
1997+.SH POSTSCRIPT CONTROL
1998+.TP
1999+.BI psPaperSize " width(pts) height(pts)"
2000+Sets the paper size for PostScript output. The
2001+.I width
2002+and
2003+.I height
2004+parameters give the paper size in PostScript points (1 point = 1/72
2005+inch).
2006+.TP
2007+.BR psPaperSize " letter | legal | A4 | A3 | match"
2008+Sets the paper size for PostScript output to a standard size. The
2009+default paper size is set when xpdf and pdftops are built, typically
2010+to "letter" or "A4". This can also be set to "match", which will set
2011+the paper size to match the size specified in the PDF file.
2012+.TP
2013+.BR psImageableArea " llx lly urx ury"
2014+Sets the imageable area for PostScript output. The four integers are
2015+the coordinates of the lower-left and upper-right corners of the
2016+imageable region, specified in points (with the origin being the
2017+lower-left corner of the paper). This defaults to the full paper
2018+size; the psPaperSize option will reset the imageable area
2019+coordinates.
2020+.TP
2021+.BR psCrop " yes | no"
2022+If set to "yes", PostScript output is cropped to the CropBox specified
2023+in the PDF file; otherwise no cropping is done. This defaults to
2024+"yes".
2025+.TP
2026+.BR psExpandSmaller " yes | no"
2027+If set to "yes", PDF pages smaller than the PostScript imageable area
2028+are expanded to fill the imageable area. Otherwise, no scalling is
2029+done on smaller pages. This defaults to "no".
2030+.TP
2031+.BR psShrinkLarger " yes | no"
2032+If set to yes, PDF pages larger than the PostScript imageable area are
2033+shrunk to fit the imageable area. Otherwise, no scaling is done on
2034+larger pages. This defaults to "yes".
2035+.TP
2036+.BR psCenter " yes | no"
2037+If set to yes, PDF pages smaller than the PostScript imageable area
2038+(after any scaling) are centered in the imageable area. Otherwise,
2039+they are aligned at the lower-left corner of the imageable area. This
2040+defaults to "yes".
2041+.TP
2042+.BR psDuplex " yes | no"
2043+If set to "yes", the generated PostScript will set the "Duplex"
2044+pagedevice entry. This tells duplex-capable printers to enable
2045+duplexing. This defaults to "no".
2046+.TP
2047+.BR psLevel " level1 | level1sep | level2 | level2sep | level3 | level3Sep"
2048+Sets the PostScript level to generate. This defaults to "level2".
2049+.TP
2050+.BI psFont " PDF\-font\-name PS\-font\-name"
2051+When the
2052+.I PDF\-font\-name
2053+font is used in a PDF file, it will be translated to the PostScript
2054+font
2055+.IR PS\-font\-name ,
2056+which is assumed to be resident in the printer. Typically,
2057+.I PDF\-font\-name
2058+and
2059+.I PS\-font\-name
2060+are the same. By default, only the Base-14 fonts are assumed to be
2061+resident.
2062+.TP
2063+.BI psNamedFont16 " PDF\-font\-name wMode PS\-font\-name encoding"
2064+When the 16-bit font
2065+.I PDF\-font\-name
2066+is used in a PDF file with the
2067+.I wMode
2068+writing mode and is not embedded, the

2110+If set to "yes", PDF forms are converted to PS procedures, and image
2111+data is preloaded. This uses more memory in the PostScript
2112+interpreter, but generates significantly smaller PS files in
2113+situations where, e.g., the same image is drawn on every page of a

2116+.BR psOPI " yes | no"
2117+If set to "yes", generates PostScript OPI comments for all images and
2118+forms which have OPI information. This option is only available if

2126+Sets the default PostScript file or print command for xpdf. Commands
2127+start with a \'|' character; anything else is a file. If the file
2128+name or command contains spaces it must be quoted. This defaults to
2129+unset, which tells xpdf to generate a name of the form <file>.ps for a
2130+PDF file <file>.pdf.

2164+characters after the first 50000 per page, avoiding extremely slow run
2165+times for PDF files that use special fonts to do shading or

2168+.TP
2169+.BR initialZoom " \fIpercentage\fR | page | width"
2170+Sets the initial zoom factor. A number specifies a zoom percentage,

2172+to the window size, or \'width', to fit the page width to the window
2173+width.

2175+.BR continuousView " yes | no"
2176+If set to "yes", xpdf will start in continuous view mode, i.e., with
2177+one vertical screoll bar for the whole document. This defaults to
2178+"no".
2179+.TP
2180+.BR enableT1lib " yes | no"
2181+Enables or disables use of t1lib (a Type 1 font rasterizer). This is
2182+only relevant if the Xpdf tools were built with t1lib support.
2183+("enableT1lib" replaces the old "t1libControl" option.) This option
2184+defaults to "yes".

2187+Enables or disables use of FreeType (a TrueType / Type 1 font
2188+rasterizer). This is only relevant if the Xpdf tools were built with

2190+"freetypeControl" option.) This option defaults to "yes".
2191+.TP
2192+.BR antialias " yes | no"
2193+Enables or disables font anti-aliasing in the PDF rasterizer. This
2194+option affects all font rasterizers. ("antialias" replaces the
2195+anti-aliasing control provided by the old "t1libControl" and
2196+"freetypeControl" options.) This default to "yes".
2197+.TP

2203+Enables or disables stroke adjustment. This defaults to "yes".
2204+.TP
2205+.BR screenType " dispersed | clustered | stochasticClustered"
2206+Sets the halftone screen type, which will be used when generating a
2207+monochrome (1-bit) bitmap. The three options are dispersed-dot
2208+dithering, clustered-dot dithering (with a round dot and 45-degree
2209+screen angle), and stochastic clustered-dot dithering. By default,
2210+"stochasticClustered" is used for resolutions of 300 dpi and higher,
2211+and "dispersed" is used for resolutions lower then 300 dpi.
2212+.TP
2213+.BI screenSize " integer"
2214+Sets the size of the (square) halftone screen threshold matrix. By
2215+default, this is 4 for dispersed-dot dithering, 10 for clustered-dot
2216+dithering, and 100 for stochastic clustered-dot dithering.
2217+.TP
2218+.BI screenDotRadius " integer"
2219+Sets the halftone screen dot radius. This is only used when
2220+screenType is set to stochasticClustered, and it defaults to 2. In
2221+clustered-dot mode, the dot radius is half of the screen size.
2222+Dispersed-dot dithering doesn't have a dot radius.
2223+.TP
2224+.BI screenGamma " float"
2225+Sets the halftone screen gamma correction parameter. Gamma values
2226+greater than 1 make the output brighter; gamma values less than 1 make
2227+it darker. The default value is 1.
2228+.TP
2229+.BI screenBlackThreshold " float"
2230+When halftoning, all values below this threshold are forced to solid
2231+black. This parameter is a floating point value between 0 (black) and
2232+1 (white). The default value is 0.
2233+.TP
2234+.BI screenWhiteThreshold " float"
2235+When halftoning, all values above this threshold are forced to solid
2236+white. This parameter is a floating point value between 0 (black) and
2237+1 (white). The default value is 1.
2238+.TP
2239+.BI urlCommand " command"
2240+Sets the command executed when you click on a URL link. The string
2241+"%s" will be replaced with the URL. (See the example below.) This
2242+has no default value.
2243+.TP
2244+.BI movieCommand " command"

2247+default value.
2248+.TP
2249+.BI mapNumericCharNames " yes | no"
2250+If set to "yes", the Xpdf tools will attempt to map various numeric
2251+character names sometimes used in font subsets. In some cases this
2252+leads to usable text, and in other cases it leads to gibberish --
2253+there is no way for Xpdf to tell. This defaults to "yes".
2254+.TP
2255+.BI mapUnknownCharNames " yes | no"
2256+If set to "yes", and mapNumericCharNames is set to "no", the Xpdf
2257+tools will apply a simple pass-through mapping (Unicode index =
2258+character code) for all unrecognized glyph names. In some cases, this
2259+leads to usable text, and in other cases it leads to gibberish --
2260+there is no way for Xpdf to tell. This defaults to "no".

2262+.BI bind " modifiers-key context command ..."
2263+Add a key or mouse button binding.

2304+The context string can include only one of each pair in the above
2305+list.
2306+
2307+.I Command
2308+is an Xpdf command (see the COMMANDS section of the
2309+.BR xpdf (1)
2310+man page for details). Multiple commands are separated by whitespace.
2311+
2312+The bind command replaces any existing binding, but only if it was
2313+defined for the exact same modifiers, key, and context. All tokens
2314+(modifiers, key, context, commands) are case-sensitive.
2315+
2316+Example key bindings:

2318+
2319+ # bind ctrl-a in any context to the nextPage
2320+ # command
2321+ bind ctrl-a any nextPage
2322+

2331+man page for more examples.
2332+.TP
2333+.BI unbind " modifiers-key context"
2334+Removes a key binding established with the bind command. This is most
2335+useful to remove default key bindings before establishing new ones
2336+(e.g., if the default key binding is given for "any" context, and you
2337+want to create new key bindings for multiple contexts).
2338+.TP

2343+.BI errQuiet " yes | no"
2344+If set to "yes", this suppresses all error and warning messages from
2345+all of the Xpdf tools. This defaults to "no".
