(These are also +sometimes also called \'Acrobat' files, from the name of Adobe's PDF +software.) Xpdf uses the Qt GUI toolkit and runs on Unix, OS X, and +Windows. +.PP +To run xpdf, type: +.PP +.RS +xpdf file.pdf +.RE +.PP +where +.I file.pdf +is your PDF file. The file name can be followed by a page number to +be displayed, prefixed with a colon: +.PP +.RS +xpdf file.pdf :18 +.RE +.PP +or by a named destination, prefixed with \'+' (this is only useful +with PDF files that provide named destination targets): +.PP +.RS +xpdf file.pdf +destinationA +.RE +.PP +If you specify multiple files, they will each be opened in a separate +tab: +.PP +.RS +xpdf file1.pdf file2.pdf :18 file3.pdf +.RE +.PP +You can also start xpdf without opening any files: +.PP +.RS +xpdf +.RE +.SH CONFIGURATION FILE +Xpdf reads a configuration file at startup. It first tries to find +the user's private config file, ~/.xpdfrc. If that doesn't exist, it +looks for a system-wide config file, typically /etc/xpdfrc (but this +location can be changed when xpdf is built). See the +.BR xpdfrc (5) +man page for details. +.SH OPTIONS +The following command line options are available. All command line +options must come before any PDF files to be opened. +.PP +Many of the options can be set with configuration file commands. +These are listed in square brackets with the description of the +corresponding command line option. +.TP +.BI \-geometry " geometry" +Set the initial window geometry. +.TP +.BI \-title " title" +Set the window title. By default, the title will be "xpdf: foo.pdf". +.TP +.BI \-open " \fR[\fPPDF-file\fR]\fP" +This option sets up a default remote server. If Xpdf is already +running (with the "-open" switch), the PDF file (if any) is opened in +a new tab. If Xpdf (with the "-open" switch) is not already running, +starts Xpdf and opens the PDF file (if any). This is useful for GUI +desktop environments, e.g., the typical double-click on a PDF file +case. +.TP +.B \-rv +Set reverse video mode. This reverses the colors of everything except +images. It may not always produce great results for PDF files which +do weird things with color. This also causes the paper color to +default to black. +.TP +.BI \-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. +.RB "[config file: " paperColor ] +.TP +.BI \-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. +.RB "[config file: " matteColor ] +.TP +.BI \-fsmattecolor " color" +Set the matte color for full-screen mode. The color can be #RRGGBB +(hexadecimal) or a named color. +.RB "[config file: " fullScreenMatteColor ] +.TP +.BI \-z " zoom" +Set 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. +.RB "[config file: " initialZoom ] +.TP +.BI \-rot " angle" +Rotate pages by 0 (the default), 90, 180, or 270 degrees. +.TP +.BI \-aa " yes | no" +Enable or disable font anti-aliasing. This defaults to "yes". +.RB "[config file: " antialias ] +.TP +.BI \-aaVector " yes | no" +Enable or disable vector anti-aliasing. This defaults to "yes". +.RB "[config file: " vectorAntialias ] +.TP +.BI \-enc " encoding-name" +Sets the encoding to use for text output. The +.I encoding\-name +must be defined with the unicodeMap command (see +.BR xpdfrc (5)). +This defaults to "Latin1" (which is a built-in encoding). +.RB "[config file: " textEncoding ] +.TP +.BI \-pw " password" +Specify the password for the PDF file. This can be either the owner +password (which will bypass all security restrictions) or the user +password. +.TP +.B \-fullscreen +Open xpdf in full-screen mode, useful for presentations. +.TP +.BI \-remote " remote-name" +Start Xpdf in remote server mode. See the REMOVE SERVER MODE section. +.TP +.BI \-display " display" +Set the X display (only available with X11). +.TP +.B \-cmd +Print commands as they're executed (useful for debugging). +.RB "[config file: " printCommands ] +.TP +.BI \-tabstate " tabstate-file" +Sets the file used by the loadTabState and saveTabState commands. +.RB "[config file: " tabStateFile ] +.TP +.BI \-cfg " config-file" +Read +.I config-file +in place of ~/.xpdfrc or the system-wide config file. +.TP +.B \-v +Print copyright and version information. +.TP +.B \-h +Print usage information. +.RB ( \-help +and +.B \-\-help +are equivalent.) +.PP +.SH CONTROLS +.SS Toolbar +.TP +.B "toggle sidebar button" +Toggles (i.e., shows or hides) the sidebar. +.TP +.B "status indicator" +This icon is animated while Xpdf is rendering a page. It turns red +when an error or warning has been issued. Clicking on it opens the +error dialog. +.TP +.B "selection mode" +This icon is an "I-beam" in linear selection mode, and an arrow in +block selection mode. Clicking on it toggles between the two +selection modes. +.TP +.B "page number entry box" +Move to a specific page number. Click in the box to activate it, type +the page number, then hit return. This will instead display and +accept page labels, if the "view - page labels" menu item is checked. +.TP +.B "left/right arrow buttons" +Go backward or forward along the history path. +.TP +.B "zoom out/in buttons" +Zoom out or in (i.e., change magnification) incrementally. +.TP +.B "zoom popup menu" +Change the zoom factor (see the description of the \-z option above). +.TP +.B "fit width button" +Change the zoom factor to fit the page width to the window width. +.TP +.B "fit page button" +Change the zoom factor to fit the page to the window size. +.TP +.B "find entry box" +Find a text string. Click in the box to activate it, type a search +string, then hit return. +.TP +.B "find next button" +Find the next occurrence of the search string. +.TP +.B "find previous button" +Find the previous occurrence of the search string. +.TP +.B "find settings button" +Display the current find settings: case sensitive (on/off), find whole +words (on/off). +.PP +.SS Menu bar +The menu bar is above the toolbar. The menu items should be +self-explanatory. +.PP +.SS Tab list +The tab list is on the left, just below the toolbar. It lists all +open tabs. +.PP +.SS Outline/layers/attachments pane +This pane is on the left, below the tab list. The popup allows you to +select from outline, layers, or attachments. +.PP +The outline is a tree-like structure of bookmarks that allows moving +within the PDF file. Not all PDF files have outlines. +.PP +Layers (a.k.a. optional content) allow parts of the PDF content to be +shown or hidden. Not all PDF files have layers. +.PP +Attachments are other files embedded within the PDF file. There is +a 'save' button for each attached file. Not all PDF files have +attachments. +.PP +.SS Text selection +In block selection mode, dragging the mouse with the left button held +down will highlight an arbitrary rectangle. Shift-clicking will +extend the selection. +.PP +In linear selection mode, dragging with the left button will highlight +text in reading order. Double-clicking or triple-clicking will select +a word or a line, respectively. Shift-clicking will extend the +selection. +.PP +Selected text can be copied to the clipboard (with the edit/copy menu +item). On X11, selected text will be available in the X selection +buffer. +.PP +.SS Links +When the mouse is over a hyperlink, the link target will be shown in a +popup near the bottom of the window. +.PP +Clicking on a hyperlink will jump to the link's destination. A link +to another PDF document will make xpdf load that document. A +\'launch' link to an executable program will display a dialog, and if +you click \'ok', execute the program. URL links are opened in a +system-dependent way. (On UNIX, Qt uses the $BROWSER environment +variable.) +.PP +.SS Mouse bindings +The left mouse button is used to select text (see above). +.PP +Clicking on a link with the middle button opens the link in a new tab. +.PP +Dragging the mouse with the middle button held down pans the window. +.PP +The right mouse button opens a popup menu (see +.BR popupMenuCmd " in " xpdfrc (5)). +.PP +.SS Key bindings +This section lists the default key bindings. Bindings can be changed +using the config file (see +.BR xpdfrc (5)). +.TP +.B control-o +Open a new PDF file via a file requester. +.TP +.B control-r +Reload the current PDF file. Note that Xpdf will reload the file +automatically (on a page change or redraw) if it has changed since it +was last loaded. +.TP +.B control-f +Find a text string. This sets keyboard focus to the \'find' box. +.TP +.B control-G +Find next occurrence. +.TP +.B control-C +Copy selected text to the clipboard. +.TP +.B control-P +Print. +.TP +.BR control-0 " (control-zero)" +Set the zoom factor to 125%. +.TP +.BR control-+ " (control-plus)" +Zoom in (increment the zoom factor by 1). +.TP +.BR control-- " (control-minus)" +Zoom out (decrement the zoom factor by 1). +.TP +.B control-s +Save PDF via a file requester. +.TP +.B control-t +Open a new tab. +.TP +.B control-n +Open a new window. +.TP +.B control-w +Close the current tab. Closes the window if this was the last open +tab.

If <ScrollLock> is active, this maintains the +relative position on the page. +.TP +.B <PageUp> +Scroll up on the current page; if already at top, move to previous +page. +.TP +.BR control-<PageUp> " or " control-<up-arrow> +Go to the previous page. If <ScrollLock> is active, this maintains +the relative position on the page. +.TP +.B <esc> +Exit full-screen mode. +.TP +.B arrows +Scroll the current page. +.TP +.B g +Set keyboard focus to the page number entry box. +.TP +.B z +Set the zoom factor to \'page' (fit page to window). +.TP +.B w +Set the zoom factor to \'width' (fit page width to window). +.SH Full-screen mode +Xpdf can be placed into full-screen mode via the +.B \-fullscreen +command line option, the \'full screen' menu item, or a binding to the +.B fullScreenMode +or +.B toggleFullScreenMode +command. +.PP +Entering full-screen mode automatically switches to single-page view +mode and to the fit-page zoom factor. +.PP +Full-screen mode can be exited via the default <esc> key binding, +or via a binding to the +.B windowMode +or +.BR toggleFullScreenMode command . +.SH COMMANDS +Xpdf's key and mouse bindings are user-configurable, using the bind +and unbind commands in the config file (see +.BR xpdfrc (5)). +The bind command allows you to bind a key or mouse button to a +sequence of one or more commands. +.PP +In commands that take arguments (inside parentheses), special +characters (namely '(', ')', ',', and '\\x01') can be escaped by +preceding them with a '\\x01' character. This is mostly useful in +things like scripts that need to be able to open arbitrary PDF files, +using the \'openFile' command. +.PP +The following commands are supported: +.TP +.B about +Open the \'about' dialog. +.TP +.B blockSelectMode +Set block selection mode. In this mode, the selection is a simple +rectangle. Any part of the page can be selected, regardless of the +content on the page. +.TP +.BI checkOpenFile( file ) +Check that +.I file +is open in the current tab, and open it if not. +.TP +.BI checkOpenFileAtDest( file, dest ) +Check that +.I file +is open in the current tab, and open it if not. In either case go to +the specified named destination. +.TP +.BI checkOpenFileAtPage( file, page ) +Check that +.I file +is open in the current tab, and open it if not. In either case go to +the specified page. +.TP +.B closeSidebar +Close the sidebar. +.TP +.B closeSidebarMoveResizeWin +Close the sidebar, resizing the window so that the document size +doesn't change, and moving the window so that the document stays in +the same place on the screen. +.TP +.B closeSidebarResizeWin +Close the sidebar, resizing the window so that the document size +doesn't change. +.TP +.B closeTabOrQuit +Close the tab. If this was the last open tab, close the window. If +this was the last window open, quit. +.TP +.B closeWindowOrQuit +Close the window. If this was the last open window, quit. +.TP +.B continuousMode +Switch to continuous view mode. +.TP +.B copy +Copy selected text to the clipboard. +.TP +.B copyLinkTarget +Copy the target of the link under the mouse cursor to the clipboard. +.TP +.B endPan +End a pan operation. +.TP +.B endSelection +End a selection. +.TP +.BI expandSidebar( n ) +Expand the sidebar by +.I n +pixels.

All remaining command line options are commands (see the +COMMANDS section). Subsequent invocations of "xpdf -remote" with the +same remote server name will send commands to the already-running +instance of xpdf. The "checkOpenFile" commands are useful here for +things like changing pages. +For example: +.PP +.RS + # Start up xpdf, and open something.pdf. + xpdf -remote foo 'openFile(something.pdf)' + + # Switch to page 7 in the already-open something.pdf. If the user + # has closed xpdf in the meantime, this will restart it and reopen + # the file. + xpdf -remote foo 'checkOpenFileAtPage(something.pdf, 7)' +.RE +.PP +.SH EXIT CODES +The Xpdf tools use the following exit codes: +.TP +0 +No error. +.TP +1 +Error opening a PDF file. +.TP +2 +Error opening an output file. +.TP +3 +Error related to PDF permissions. +.TP +99 +Other error. +.SH AUTHOR +The xpdf software and documentation are copyright 1996-2022 Glyph & +Cog, LLC. +.SH "SEE ALSO" +.BR pdftops (1), +.BR pdftotext (1), +.BR pdftohtml (1), +.BR pdfinfo (1), +.BR pdffonts (1), +.BR pdfdetach (1), +.BR pdftoppm (1), +.BR pdftopng (1), +.BR pdfimages (1), +.BR xpdfrc (5) +.br +.B http://www.xpdfreader.com/ |
