Configuration SettingsWhen the library is initialized, it reads a configuration file (see the
pdfInitLibraryfunction). The configuration file syntax is shared across all of the Xpdf libraries, as well as the Xpdf open source applications.
Configuration changes can also be made with the
xpdfrc(5) File Formats Manual xpdfrc(5) NAME xpdfrc - configuration file for Xpdf tools (version 4.01) 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 /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 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 ignored. Arguments may be quoted, using "double-quote" characters, e.g., for file names that contain spaces. The following sections list all of the configuration options, sorted into functional groups. There is an examples section at the end. 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. GENERAL FONT CONFIGURATION fontFile PDF-font-name font-file Maps a PDF font, PDF-font-name, to a font for display or Post- Script output. The font file, font-file, can be any type allowed in a PDF file. This command can be used for 8-bit or 16-bit (CID) fonts. fontDir dir Specifies a search directory for font files. There can be mul- tiple fontDir commands; all of the specified directories will be searched in order. The font files can be Type 1 (.pfa or .pfb) or TrueType (.ttf or .ttc); other files in the directory will be ignored. The font file name (not including the extension) must exactly match the PDF font name. This search is performed if the font name doesn't match any of the fonts declared with the fontFile command. There are no default fontDir directories. fontFileCC registry-ordering font-file Maps the registry-ordering character collection to a font for display or PostScript output. This mapping is used if the font name doesn't match any of the fonts declared with the fontFile, fontDir, psResidentFont16, or psResidentFontCC commands. POSTSCRIPT FONT CONFIGURATION psFontPassthrough yes | no If set to "yes", pass 8-bit font names through to the PostScript output without substitution. Fonts which are not embedded in the PDF file are expected to be available on the printer. This defaults to "no". psResidentFont PDF-font-name PS-font-name When the 8-bit font PDF-font-name is used (without embedding) 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. psResidentFont16 PDF-font-name wMode PS-font-name encoding When the 16-bit (CID) font PDF-font-name with writing mode wMode is used (without embedding) in a PDF file, it will be translated to the PostScript font PS-font-name, which is assumed to be res- ident in the printer. The writing mode must be either 'H' for horizontal or 'V' for vertical. The resident font is assumed to use the specified encoding (which must have been defined with the unicodeMap command). psResidentFontCC registry-ordering wMode PS-font-name encoding When a 16-bit (CID) font using the registry-ordering character collection and wMode writing mode is used (without embedding) in a PDF file, the PostScript font, PS-font-name, is substituted for it. The substituted font is assumed to be resident in the printer. The writing mode must be either 'H' for horizontal or 'V' for vertical. The resident font is assumed to use the spec- ified 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. This defaults to "yes". 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. This defaults to "yes". 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 imageable 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". psUseCropBoxAsPage yes | no If set to "yes", PostScript output treats the CropBox as the page size. By default, this is "no", and the MediaBox is used as the page size. psExpandSmaller yes | no If set to "yes", PDF pages smaller than the PostScript imageable area are expanded to fill the imageable area. Otherwise, no scaling 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 imageable 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". psLevel level1 | level1sep | level2 | level2gray | level2sep | level3 | level3gray | level3Sep Sets the PostScript level to generate. This defaults to "level2". 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 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". psASCIIHex yes | no If set to "yes", the ASCIIHexEncode filter will be used instead of ASCII85Encode for binary data. This defaults to "no". psLZW yes | no If set to "yes", the LZWEncode filter will be used for lossless compression in PostScript output; if set to "no", the RunLength- Encode filter will be used instead. LZW generates better com- pression (smaller PS files), but may not be supported by some printers. This defaults to "yes". psUncompressPreloadedImages yes | no If set to "yes", all preloaded images in PS files will uncom- pressed. If set to "no", the original compressed images will be used when possible. The "yes" setting is useful to work around certain buggy PostScript interpreters. This defaults to "no". psMinLineWidth float Set the minimum line width, in points, for PostScript output. The default value is 0 (no minimum). psRasterResolution float Set the resolution (in dpi) for rasterized pages in PostScript output. (Pdftops will rasterize pages which use transparency.) This defaults to 300. psRasterMono yes | no If set to "yes", rasterized pages in PS files will be monochrome (8-bit gray) instead of color. This defaults to "no". psRasterSliceSize pixels When rasterizing pages, pdftops splits the page into horizontal "slices", to limit memory usage. This option sets the maximum slice size, in pixels. This defaults to 20000000 (20 million). psAlwaysRasterize yes | no If set to "yes", all PostScript output will be rasterized. This defaults to "no". psNeverRasterize yes | no Pdftops rasterizes an pages that use transparency (because Post- Script doesn't support transparency). If psNeverRasterize is set to "yes", rasterization is disabled: pages will never be rasterized, even if they contain transparency. This will likely result in incorrect output for PDF files that use transparency, and a warning message to that effect will be printed. This defaults to "no". fontDir dir See the description above, in the DISPLAY FONTS section. TEXT CONTROL AND CHARACTER MAPPING 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 options 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 extremely slow run times for PDF files that use special fonts to do shading or cross-hatching. This defaults to "yes". 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 indexes. Each occurrence of in-hex will be converted to the specified output sequence. unicodeRemapping remap-file Remap Unicode characters when doing text extraction. This spec- ifies a file that maps from a particular Unicode index to zero or more replacement Unicode indexes. Each line of the remap file represents one Unicode character: in-hex out-hex1 out-hex2 ... Any Unicode characters not listed will be left unchanged. This function is typically used to remap things like non-breaking spaces, soft hyphens, ligatures, etc. unicodeMap encoding-name map-file Specifies the file with mapping from Unicode to encoding-name. These encodings are used for 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 encod- ing: 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 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 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 directories 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. 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". 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. (For CID fonts, setting mapNumericCharNames to "no" is unnecessary.) 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". mapExtTrueTypeFontsViaUnicode yes | no When rasterizing text using an external TrueType font, there are two options for handling character codes. If mapExtTrueType- FontsViaUnicode is set to "yes", Xpdf will use the font encod- ing/ToUnicode info to map character codes to Unicode, and then use the font's Unicode cmap to map Unicode to GIDs. If mapExt- TrueTypeFontsViaUnicode is set to "no", Xpdf will assume the character codes are GIDs (i.e., use an identity mapping). This defaults to "yes". dropFont font-name Drop all text drawn in the specified font. To drop text drawn in unnamed fonts, use: dropFont "" There can be any number of dropFont commands. RASTERIZER SETTINGS 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". disableFreeTypeHinting yes | no If this is set to "yes", FreeType hinting will be forced off. This option defaults to "no". 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". antialiasPrinting yes | no If this is "yes", bitmaps sent to the printer will be antialiased (according to the "antialias" and "vectorAntialias" settings). If this is "no", printed bitmaps will not be antialiased. This defaults to "no". strokeAdjust yes | no | cad Sets the stroke adjustment mode. If set to "no", no stroke adjustment will be done. If set to "yes", normal stroke adjust- ment will be done: horizontal and vertical lines will be moved by up to half a pixel to make them look cleaner when vector anti-aliasing is enabled. If set to "cad", a slightly different stroke adjustment algorithm will be used to ensure that lines of the same original width will always have the same adjusted width (at the expense of allowing gaps and overlaps between adjacent lines). This defaults to "yes". forceAccurateTiling yes | no If this is set to "yes", the TilingType is forced to 2 (no dis- tortion) for all tiling patterns, regardless of the setting in the pattern dictionary. This defaults to "no". 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. minLineWidth float Set the minimum line width, in device pixels. This affects the rasterizer only, not the PostScript converter (except when it uses rasterization to handle transparency). The default value is 0 (no minimum). enablePathSimplification yes | no If set to "yes", simplify paths by removing points where it won't make a significant difference to the shape. The default value is "no". overprintPreview yes | no If set to "yes", generate overprint preview output, honoring the OP/op/OPM settings in the PDF file. Ignored for non-CMYK out- put. The default value is "no". VIEWER SETTINGS These settings only apply to the Xpdf GUI PDF viewer. initialZoom percentage | page | width 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, or 'width', to fit the page width to the window width. defaultFitZoom percentage If xpdf is started with fit-page or fit-width zoom and no window geometry, it will calculate a desired window size based on the PDF page size and this defaultFitZoom value. I.e., the window size will be chosen such that exactly one page will fit in the window at this zoom factor (which must be a percentage). The default value is based on the screen resolution. initialSidebarState yes | no If set to "yes", xpdf opens with the sidebar (tabs, outline, etc.) visible. If set to "no", xpdf opens with the sidebar collapsed. The default is "yes". paperColor color Set the "paper color", i.e., the background of the page display. The color can be #RRGGBB (hexadecimal) or a named color. This option will not work well with PDF files that do things like filling in white behind the text. matteColor color Set the matte color, i.e., the color used for background outside the actual page area. The color can be #RRGGBB (hexadecimal) or a named color. fullScreenMatteColor color Set the matte color for full-screen mode. The color can be #RRGGBB (hexadecimal) or a named color. popupMenuCmd title command ... Add a command to the popup menu. Title is the text to be dis- played in the menu. Command is an Xpdf command (see the COM- MANDS section of the xpdf(1) man page for details). Multiple commands are separated by whitespace. maxTileWidth pixels Set the maximum width of tiles to be used by xpdf when rasteriz- ing pages. This defaults to 1500. maxTileHeight pixels Set the maximum height of tiles to be used by xpdf when raster- izing pages. This defaults to 1500. tileCacheSize tiles Set the maximum number of tiles to be cached by xpdf when ras- terizing pages. This defaults to 10. workerThreads numThreads Set the number of worker threads to be used by xpdf when raster- izing pages. This defaults to 1. launchCommand command Sets the command executed when you click on a "launch"-type link. The intent is for the command to be a program/script which determines the file type and runs the appropriate viewer. The command line will consist of the file to be launched, fol- lowed by any parameters specified with the link. Do not use "%s" in "command". By default, this is unset, and Xpdf will simply try to execute the file (after prompting the user). 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. defaultPrinter printer Sets the default printer used in the viewer's print dialog. 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 esc insert delete home end pgup pgdn left / right / up / down (arrow keys) f1 .. f35 (function keys) mousePress1 .. mousePress7 (mouse buttons) mouseRelease1 .. mouseRelease7 (mouse buttons) mouseClick1 .. mouseClick7 (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). tabStateFile path Sets the file used by the loadTabState and saveTabState commands (see the xpdf(1) man page for more information). MISCELLANEOUS SETTINGS drawAnnotations yes | no If set to "no", annotations will not be drawn or printed. The default value is "yes". drawFormFields yes | no If set to "no", form fields will not be drawn or printed. The default value is "yes". enableXFA yes | no If set to "yes", an XFA form (if present) will be rendered in place of an AcroForm. If "no", an XFA form will never be ren- dered. This defaults to "yes". 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".
