Description
gv allows to view and navigate through PostScript and PDF documents on an X display by providing a user interface for the ghostscript interpreter. Please note that gv is derived from Tim Theisen's ghostview 1.5.

Options

filename
    The name of the file to be displayed. The file ending ".ps" may be omitted. "filename" may point to a compressed file (gzipped, zipped or compressed). Viewing PDF files requires at least ghostscript version 4.x.

-ad <resource file>
    Read and use additional resources from the file <resource file>. These resources have higher priority than those provided in the context of the -style <resource file> option.

-antialias, -noantialias
    Whether to use antialiasing.

-arguments <arguments>
    Start ghostscript with additional options as specified by the string <arguments>.

-center, -nocenter
    Whether the page should be centered automatically.

-dsc, -nodsc
    Determines if document structuring convention (DSC) comments should be respected or ignored. If -nodsc is used gv will not attempt to examine the structure of the document but will pass the file to the ghostscript interpreter as a whole. In this case no page numbers are shown and freely moving around in the document is not possible. This option may help when viewing files not conforming to the document structuring conventions.

-eof, -noeof
    Defines the behaviour of the postscript scanner used to examine the structure of the document. If -noeof is used the scanner will ignore end of file (EOF) comments. This may help when viewing documents which import other documents without enclosing them within the proper "BeginDocument" and "EndDocument" comments. If -eof is used, the scanner treats an EOF comment as marking the end of the file.

-pixmap, -nopixmap
    If -pixmap is used gv tries to maintain off-screen regions of the displayed page by allocating a sufficiently large pixmap. If -nopixmap is used the X Server is responsible for maintaining obscured portions of the displayed page (see also the "useBackingPixmap" resource).

-v  Print the version number of gv to standard output and exit.

-h, -?
    Display a short help message and exit.

-help
    Display a more explicit help message and exit.

-scale <n>
    Selects the scale entry <n> relative to the scale 1.0. <n> must be an integer.

-scalebase <n>
    Selects the scale base <n>.

-monochrome, -grayscale, -color
    Sets the color palette to be used.

-media <media>
    Selects the paper size to be used. Valid values are names of paper sizes that appear in the list of page medias as given by the medias resource.

-page <label>
    Display the page with label <label> first.

-portrait, -landscape, -seascape, -upsidedown
    Sets the orientation.

-quiet, -noquiet
    Whether to start ghostscript with the -dQUIET option.

-resize, -noresize
    Whether gv is allowed to automatically fit the size of its window to the size of the displayed page.

-safer, -nosafer
    Whether to start ghostscript with the -dSAFER option.

-spartan
    This is a shortcut for "-style gv_spartan.dat".

-style <resource file>
    Read and use additional resources from the file <resource file>. These resources have lower priority than those provided in the context of the -ad <resource file> option.

-swap, -noswap
    Whether to interchange the meaning of the orientations landscape and seascape.

-watch, -nowatch
    The -watch option causes gv to check the document periodically. If changes are detected gv will automatically display the newer version of the file. The document is by default checked once every second. This can be changed via the watchFileFrequency resource. Note that sending gv the SIGHUP signal also causes an update of the displayed document. This method may be used by document creators to trigger gv remotely.

Resources
Resource files In general gv does not depend on any external resource files. However, when starting gv, preferences are read from a system specific resource file. The name of this file is as described by the "XFILESEARCHPATH" environment variable, or, if this variable is not defined, implementation dependant. In most cases it is "/usr/X11/lib/X11/app-defaults/GV". Administrators may want to modify this file in order to set up gv according to the local needs of their system. a user specific resource file. The name of this file is either "~/.gv" or as described by the "XUSERFILESEARCHPATH" environment variable. The files "gv_user.ad" and "gv_system.ad" (located in the library directory of gv, which is most probably either "/usr/local/lib/gv/" or "/usr/lib/gv/" may serve as a basis for constructing the user and system specific resource files. Note that the user and system specific resource files are not the only sources of preferences taken into account when gv is started. However, in practice these are the most important. Resources of gv The following describes some of the resources of gv. The precise syntax of some of the resource values may be inferred from the appended default system specific resource file.

antialias
    Whether antialiasing should be used. Valid values are "True" and "False".

autoCenter
    Whether the displayed page should automatically be centered (for instance when opening a new file). Valid values are "True" and "False".

autoResize
    Whether gv is allowed to resize the main window according to the size of the current page. Valid values are "True" and "False".

confirmPrint
    Whether printing requires an extra confirmation. Valid values are "True" and "False".

confirmQuit
    Whether leaving gv requires extra confirmation. Valid values are "0" (Never), "1" (When processing) and "2" (Always). The default value is "1", which causes a confirmation request when trying to leave gv in the presence of pending PDF to Postscript conversions.

scrollingEyeGuide
    If this resource is "True" scrolling via the keyboard causes a temporary border to be drawn around the previously visible area of the page. Allowed values are "True" and "False".

ignoreEOF
    Defines the behaviour of the postscript scanner as described in the Options section. Valid values are "True" and "False".

respectDSC
    Determines whether gv should attempt to respect document structuring comments. Valid values are "True" and "False".

reverseScrolling
    Defines the interpretation of directions when scrolling with the mouse. Valid values are "True" and "False".

swapLandscape
    Whether the meaning of "landscape" and "seacape" should be interchanged. Valid values are "True" and "False".

scratchDir
    Specifies a directory used to store temporary data.

defaultSaveDir
    Specifies the default destination directory for files to be saved.

useBackingPixmap
    If the value of this resource is "False" the X Server is advised that saving off-screen pixels of the displayed page would be beneficial (maintaining backing store). In this case gv does not actively maintain the contents of the page but relies on the X Server. The server is, however, always free to stop maintaining backing backing store. If the value of this resource is "True" the X Server is advised that maintaining backing store is not useful. In this case gv attempts to allocate a sufficiently large pixmap to store the contents of the displayed page.

watchFile
    Whether the document should be checked periodically and updated automatically if changes are detected. Valid values are "True" and "False".

watchFileFrequency
    Defines the time in milliseconds elapsing between successive checks of the document when watchFile is set to "True". Allowed values must be larger than 500.

printCommand
    The command used for printing a file. The command may contain multiple '%s' wildcards which will be replaced by the name of the file to be printed.

gsInterpreter
    The command used to start the ghostscript interpreter.

gsCmdScanPDF
    The command used to extract document structuring comments from a PDF file.

gsCmdConvPDF
    The command used to convert a PDF file to PostScript.

gsX11Device
    The ghostscript command line option which activates the "X11" device.

gsX11AlphaDevice
    The ghostscript command line option which activates the "X11" device with antialiasing enabled.

gsSafer
    Determines whether ghostscript should be started with the "-dSAFER" command line option.

gsQuiet
    Determines whether ghostscript should be started with the "-dQUIET" command line option.

gsArguments
    May be used to provide additional command line options for the ghostscript interpreter. Starting gv with the "-arguments <arguments>" option will override this resource setting.

magMenu
    Describes the menu that pops up when preparing to to zoom an area of the displayed page.

dirs
    Defines a list of directories accessible via the Directories menu in the file selection window. The special value "Home" corresponds to the users home directory, the value "Tmp" corresponds to the scratch directory as defined by the scratchDir resource.

filter
    Defines the default filter to be used when displaying a directory contents in the file selection window. A filter is specified according to the syntax

       <filter>    := [<filespecs>] [no <filespecs>]
       <filespecs> := <filespec> [<filespecs>]
       <filespec>  := filename possibly including wildcards '*'
                      which match any character.

    Example: The filter

       GV*filter: *.ps *.pdf no .*

    screens out all files with names starting with a dot and keeps of the remaining ones only those which end on ".ps" or ".pdf".

filters
    Defines a list of filters offered in the Filters menu of the file selection window. The filter "None" has a special meaning causing all files to be displayed when the corresponding menu entry is selected.

miscMenuEntries
    Describes the menu that pops up when clicking with the third mouse button on the displayed page. The value of this resource is a list of menu entries. Allowed entries are "update", "redisplay", "toggle_current", "toggle_even", "toggle_odd", "unmark", "stop", "print_all", "print_marked", "save_all", "save_marked" and "line".

showTitle
    Whether the name of the displayed document should be shown in the title bar of the window. The name of gv's icon will also change accordingly if this resource is set to "True".

maximumWidth, maximumHeight
    When resizing gv will not attempt to exceed the size specified by these resources. These resources may be specified as a positive integer or as "screen", optionally combined with a positive or negative offset. The default values listed above provide examples for this syntax. "screen" will automatically be replaced by the size of the screen.

minimumWidth, minimumHeight
    Defines a minimum size for the main window. Valid values for both resources are positive integers larger than 200.

scale
    Sets the initial scale. The value of this resource is the offset of the scale to be selected relative to the scale 1.0 in the the "Scale" menu.

scaleBase
    Selects the initial scale base. The value of this resource should be a positive integer.

scales
    Defines the available scales bases and scales in the "Scale" menu.

orientation
    Sets the initial orientation. Valid values are "portrait", "landscape","seascape", "upside-down" and "automatic". "automatic" causes gv to attempt to derive the correct orientation from document structuring comments.

fallbackOrientation
    Defines the paper-size to be used when automatic orientation detetction fails. Valid values are "portrait", "landscape","seascape" and "upside-down".

medias
    A list describing the page medias known to gv. List entries starting with "!" or "#" will not appear in the "Media" menu but will still be used for automatic paper size detection.

pagemedia
    Sets the paper size. Allowd values are as given in the above list of paper-sizes. Specifying "automatic" causes gv to attempt to derive the correct paper-size from document structuring comments.

fallbackPageMedia
    Defines the paper-size to be used when automatic paper-size detetction fails. Valid values are as given in the above list of paper-sizes. The default user and system specific resource file

Mouse and key bindings

Mouse bindings in the Main and the Zoom window
    The following mouse events are defined when the mouse pointer is either on the displayed page or on a zoomed area:

- press button 1, move mouse, release button 1
    Scrolls the displayed page 'proportionally'.

- press button 3, move mouse, release button 3
    Scrolls the displayed page 'absolutely'.

- double-click with button 1
    In the main window this displays the previous/next page if the double-click occured in the left/right half of the window. In a zoom window it does nothing.

- press button 2, release button 2
    Pops up a small menu which allows to choose a magnification for a certain area around the current mouse position. After selecting a magnification a zoom window pops up displaying the area at the chosen scale.

- press button 2, move mouse, release button 2
    This draws and thereby defines a rectangular region which can be displayed in a zoom window. The magnification for the area can be selected by means of a popup menu which appears after releasing button 2.

- press button 1, press button 2
    Redisplays the current page. This event sequence works only in the main window.

- press button 3, release button 3
    Pops up a small menu which offers a few standard actions like 'Redisplay', 'Mark Page', etc.

Mouse bindings in the File Selection popup
    The following mouse events are defined when the mouse pointer is in the window of either a file or a directory list:

- press button 1, move mouse, release button 1
    Scrolls a file or directory list 'proportionally'.

- press button 2, move mouse, release button 2
    Scrolls a file or directory list 'absolutely'.

- press button 2, release button 2
    Scrolls a file or directory list one page up/down if the button was pressed in the upper/lower half of the list.

- double-click with button 1 on a filename
    Selects the file and closes the File Selection popup.

- click with button 1 on a directory name
    Causes the contents of this directory to be displayed.

Mouse bindings in the Table of Contents
    The following mouse events are defined when the mouse pointer is in the window showing a list of page numbers of the current file (table of contents):

- press button 1, move mouse, release button 1
    Scrolls the table of contents.

- press button 1 on a page number
    Go to this page.

- press button 2 on a page number
    Mark this page if it is unmarked, but unmark it if it is marked.

- press button 2, move mouse, release button 2
    Marks/unmarks all unmarked/marked pages in the region crossed by the mouse pointer during the movement.

Mouse bindings in the Panner widget
    The Panner widget is the rectangular region located close to the left edge of the main window. It indicates the size and the position of the visible area of the current page relative to the total page. The following mouse events are defined when the mouse pointer is in this region:

- press button 1, move mouse
    Scrolls the displayed page.

- press button 2
    Display the previous page.

- press button 3
    Display the next page.

Mouse bindings in the
    The ">>" and "<<" buttons are used to move to another page. The following mouse events are defined:

- press button 1
    Move 1 page forward/backwards.

- press button 2
    Move 5 pages forward/backwards.

- press button 3
    Move 10 pages forward/backwards.

Comments about the user interface

Scales
    The "Scale" menu which allows to view the document at different sizes is divided into two parts. The first part shows a list of available scale bases, the second part, separated by a line, lists the relative scales which are applied with respect to the selected scale base. By default two scales bases are available, the "Natural size" and the "Pixel based" base. When choosing the "Pixel based" scale base a relative scale of 1.0 causes one postscript point to correspond to one pixel on the screen. When viewing a document at a relative scale of 1.0 using the "Natural size" base the page should appear in its real size, as if printed on paper. For the "Natural size" base to work properly gv has to know the correct size of the root window. Automatic detection of this size unfortunately only provides approximate results, therefore it is best if it is provided by the user. To do so the resource

       GV.screenSize:  <width> x <height>

    should be added to the "SCREEN_RESOURCES" property of the screen the document is viewed on, with <width> and <height> describing the width and height of the root window in units of millimeters. For instance by using the command

       echo "GV.screenSize: 396 x 291" | xrdb -override -screen

    a width of 346 mm and a height of 291 mm will be used for the "Natural size" scale base. Alternatively the resource

       GV.screenSize_<machine>_<disp>_<scr>:  <width> x <height>

    may be added to a resource file read by gv. Here <machine> ,<disp> and ANGLED) describe the display on which gv displays the document. For instance, if the display is set to "tic.tac.toe.wo:0.1" the resource should be specified as

       GV.screenSize_tic_0_1: 396 x 291

    Note that this method doesn't work on VMS. As a last alternative the resource

       GV.screenSize:  <width> x <height>

    may be added to one of the resource files. However, for obvious reasons this method should be used only on single user machines.

Scrolling
    It is probably a de facto standard for user interfaces that windows are supposed to be scrolled by means of scrollbars attached to their sides. However, for various reasons the use of scrollbars has been minimized in gv. Instead, in all windows with obscured data, scrolling may be performed by pressing button1, moving the mouse, then releasing button1 directly in the window. This includes the displayed page, zoom popups, the table of contents and the file and directory lists displayed in the file selection popup.

Displaying new versions of a document
    During document creation it is usually desirable to always display the newest version of the document in work. Instead of explicitly loading it via the file selection popup the most recent version can be displayed by pressing the "Redisplay" button in the main window (VMS users should use the "Update File" entry in the "File" menu). Choosing the "Redisplay" entry in the menu that pops up when clicking with the third mouse button anywhere on the displayed page certainly has the same effect. More comfortable is the "Watch File" feature which may be switched on by selecting the corresponding entry in the "State" menu. If activated gv will check every now and then if a new version of the displayed file exists. If so it will be displayed automatically. By default the file is checked about once every second. Finally it may also be left to the document creating program to trigger gv to update its display. To do so the program should send the SIGHUP signal to gv. For instance at the end of a shell script generating a postscript file from latex sources the line

       kill -SIGHUP <gv_pid>

    may be added (here <gv_pid> is the process id of gv). Executing the script and thereby creating a new version of the document will then also cause the result to be displayed instantaneously. Please note that this feature is available only on X11 R6 based systems.
