NAME
xpdf - Portable Document Format (PDF) file viewer for X (version 3.04)

SYNOPSIS
xpdf [options] [PDF-file [page | +dest]]

DESCRIPTION
Xpdf is a viewer for Portable Document Format (PDF) files. (These are also sometimes also called 'Acrobat' files, from the name of Adobe's PDF software.) Xpdf runs under the X Window System on UNIX, VMS, and OS/2.

To run xpdf, simply type:

    xpdf file.pdf

where file.pdf is your PDF file. The file name can be followed by a number specifying the page which should be displayed first, e.g.:

    xpdf file.pdf 18

You can also give a named destination, prefixed with '+' in place of the page number. (This is only useful with PDF files that provide named destination targets.)

You can also start xpdf without opening any files:

    xpdf

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 /usr/local/etc/xpdfrc (but this location can be changed when xpdf is built). See the xpdfrc(5) man page for details.

OPTIONS
Many of the following options can be set with configuration file commands or X resources. These are listed in square brackets with the description of the corresponding command line option.

-g geometry
    Set the initial window geometry. (-geometry is equivalent.) [X resource: xpdf.geometry]

-title title
    Set the window title. By default, the title will be "xpdf: foo.pdf". [X resource: xpdf.title]

-cmap
    Install a private colormap. This is ignored on TrueColor visuals. [X resource: xpdf.installCmap]

-rgb number
    Set the size of largest RGB cube xpdf will try to allocate. The default is 5 (for a 5x5x5 cube); set to a smaller number to conserve color table entries. This is ignored with private colormaps and on TrueColor visuals. [X resource: xpdf.rgbCubeSize]

-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. [X resource: xpdf.reverseVideo]

-papercolor color
    Set the "paper color", i.e., the background of the page display. This will not work too well with PDF files that do things like filling in white behind the text. [X resource: xpdf.paperColor]

-mattecolor color
    Set the matte color, i.e., the color used for background outside the actual page area. (There is a separate setting, xpdf.fullScreenMatteColor, for full-screen mode.) [X resource: xpdf.matteColor]

-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. [config file: initialZoom; or X resource: xpdf.initialZoom]

-cont
    Start in continuous view mode, i.e., with one vertical scroll bar for the whole document. [config file: continuousView]

-freetype yes | no
    Enable or disable FreeType (a TrueType / Type 1 font rasterizer). This defaults to "yes". [config file: enableFreeType]

-aa yes | no
    Enable or disable font anti-aliasing. This defaults to "yes". [config file: antialias]

-aaVector yes | no
    Enable or disable vector anti-aliasing. This defaults to "yes". [config file: vectorAntialias]

-ps PS-file
    Set the default file name for PostScript output (i.e., the name which will appear in the print dialog). This can also be of the form '|command' to pipe the PostScript through a command. [config file: psFile]

-paper size
    Set the paper size to one of "letter", "legal", "A4", or "A3". This can also be set to "match", which will set the paper size to match the size specified in the PDF file. [config file: psPaperSize]

-paperw size
    Set the paper width, in points. [config file: psPaperSize]

-paperh size
    Set the paper height, in points. [config file: psPaperSize]

-level1
    Generate Level 1 PostScript. The resulting PostScript files will be significantly larger (if they contain images), but will print on Level 1 printers. This also converts all images to black and white. [config file: psLevel]

-enc encoding-name
    Sets the encoding to use for text output. The encoding-name must be defined with the unicodeMap command (see xpdfrc(5)). This defaults to "Latin1" (which is a built-in encoding). [config file: textEncoding]

-eol unix | dos | mac
    Sets the end-of-line convention to use for text output. [config file: textEOL]

-opw password
    Specify the owner password for the PDF file. Providing this will bypass all security restrictions.

-upw password
    Specify the user password for the PDF file.

-fullscreen
    Open xpdf in full-screen mode, useful for presentations.

-remote name
    Start/contact xpdf remote server with specified name (see the REMOTE SERVER MODE section below).

-exec command
    Execute a command (see the COMMANDS section below) in an xpdf remote server window (with -remote only).

-reload
    Reload xpdf remote server window (with -remote only).

-raise
    Raise xpdf remote server window (with -remote only).

-quit
    Kill xpdf remote server (with -remote only).

-cmd
    Print commands as they're executed (useful for debugging). [config file: printCommands]

-q  Don't print any messages or errors. [config file: errQuiet]

-cfg config-file
    Read config-file in place of ~/.xpdfrc or the system-wide config file.

-v  Print copyright and version information.

-h  Print usage information. (-help and --help are equivalent.)

Several other standard X options and resources will work as expected:

-display display
    [X resource: xpdf.display]

-fg color
    (-foreground is equivalent.) [X resource: xpdf*Foreground]

-bg color
    (-background is equivalent.) [X resource: xpdf*Background]

-font font
    (-fn is equivalent.) [X resource: xpdf*fontList]

The color and font options only affect the user interface elements, not the PDF display (the 'paper').

The following X resources do not have command line option equivalents:

xpdf.toolTipEnable
    Enables (if set to true) or disables (if set to false) the tool-tips on the toolbar buttons.

xpdf.fullScreenMatteColor
    Sets the matte color to be used in full-screen mode. The default setting is "black".

CONTROLS

  On-screen controls, at the bottom of the xpdf window

left/right arrow buttons
    Move to the previous/next page.

double left/right arrow buttons
    Move backward or forward by ten pages.

dashed left/right arrow buttons
    Move backward or forward along the history path.

'Page' entry box
    Move to a specific page number. Click in the box to activate it, type the page number, then hit return.

zoom popup menu
    Change the zoom factor (see the description of the -z option above).

binoculars button
    Find a text string.

print button
    Bring up a dialog for generating a PostScript file. The dialog has options to set the pages to be printed and the PostScript file name. The file name can be '-' for stdout or '|command' to pipe the PostScript through a command, e.g., '|lpr'.

'?' button
    Bring up the 'about xpdf' window.

link info
    The space between the '?' and 'Quit' buttons is used to show the URL or external file name when the mouse is over a link.

'Quit' button
    Quit xpdf.

  Menu
Pressing the right mouse button will post a popup menu with the following commands:

Open...
    Open a new PDF file via a file requester.

Open in new window...
    Create a new window and open a new PDF file via a file requester.

Reload
    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.

Save as...
    Save the current file via a file requester.

Continuous view
    Toggles between single page and continuous view modes.

Rotate counterclockwise
    Rotate the page 90 degrees counterclockwise.

Rotate clockwise
    Rotate the page 90 degrees clockwise. The two rotate commands are intended primarily for PDF files where the rotation isn't correctly specified in the file.

Zoom to selection
    Zoom in to the currently selected rectangle.

Close
    Close the current window. If this is the only open window, the document is closed, but the window is left open (i.e., this menu command won't quit xpdf).

Quit
    Quit xpdf.

  Outline
If the PDF contains an outline (a.k.a., bookmarks), there will be an outline pane on the left side of the window. The width of the outline pane is adjustable with a vertical split bar via the knob near its bottom end.

  Text selection
Dragging the mouse with the left button held down will highlight an arbitrary rectangle. Any text inside this rectangle will be copied to the X selection buffer.

  Links
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 call an external command (see the WEB BROWSERS section below).

  Panning
Dragging the mouse with the middle button held down pans the window.

WEB BROWSERS
If you want to run xpdf automatically from netscape or mosaic (and probably other browsers) when you click on a link to a PDF file, you need to edit (or create) the files .mime.types and .mailcap in your home directory. In .mime.types add the line:

    application/pdf pdf

In .mailcap add the lines:

    # Use xpdf to view PDF files.
    application/pdf; xpdf -q %s

Make sure that xpdf is on your executable search path.

When you click on a URL link in a PDF file, xpdf will execute the command specified by the urlCommand config file option, replacing an occurrence of '%s' with the URL. For example, to call netscape with the URL, add this line to your config file:

    urlCommand "netscape -remote 'openURL(%s)'"

COMMANDS
Xpdf's key and mouse bindings are user-configurable, using the bind and unbind options in the config file (see xpdfrc(5)). The bind command allows you to bind a key or mouse button to a sequence of one or more commands.

followLinkNoSel
    Same as followLink, but does nothing if there is a non-empty selection. (This is useful as a mouse button binding.)

followLinkInNewWinNoSel
    Same as followLinkInNewWin, but does nothing if there is a non-empty selection. (This is useful as a mouse button binding.)

  Default Bindings
The default mouse bindings are as follows:

    bind ctrl-l         any         redraw
    bind ctrl-w         any         closeWindowOrQuit
    bind ?              any         about
    bind q              any         quit
    bind Q              any         quit

Previous versions of xpdf included a "viKeys" X resource. It is no longer available, but the following bindings are equivalent:

    bind h any scrollLeft(16)
    bind l any scrollRight(16)
    bind k any scrollUp(16)
    bind j any scrollDown(16)

REMOTE SERVER MODE
Xpdf can be started in remote server mode by specifying a server name (in addition to the file name and page number). For example:

    xpdf -remote myServer file.pdf

If there is currently no xpdf running in server mode with the name 'myServer', a new xpdf window will be opened. If another command:

    xpdf -remote myServer another.pdf 9

is issued, a new copy of xpdf will not be started. Instead, the first xpdf (the server) will load another.pdf and display page nine. If the file name is the same:

    xpdf -remote myServer another.pdf 4

the xpdf server will simply display the specified page.

The -raise option tells the server to raise its window; it can be specified with or without a file name and page number.

The -quit option tells the server to close its window and exit.

EXIT CODES
The Xpdf tools use the following exit codes:

0   No error.

1   Error opening a PDF file.

2   Error opening an output file.

3   Error related to PDF permissions.

99  Other error.
