    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).  View-
              ing  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)  com-
              ments.  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 suffi-
              ciently 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 automati-
              cally display the newer version of the file.  The docu-
              ment  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
    
         o    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,  imple-
              mentation    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 accord-
              ing to the local needs of their system.
    
         o    a user specific resource file.  The name of  this  file
              is  either  "~/.gv"  or  as  described  by  the "XUSER-
              FILESEARCHPATH" 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 cen-
              tered  (for  instance  when opening a new file).  Valid
              values are "True" and "False".
    
         autoResize
              Whether gv is allowed to resize the main window accord-
              ing  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 previ-
              ously 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  docu-
              ment 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  suc-
              cessive 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  com-
              ments 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 Direc-
              tories  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", option-
              ally  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  "por-
              trait",   "landscape","seascape",   "upside-down"   and
              "automatic".   "automatic"  causes  gv  to  attempt  to
              derive  the correct orientation from document structur-
              ing comments.
    
         fallbackOrientation
              Defines the paper-size to be used when automatic orien-
              tation  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 mag-
                   nification  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 releas-
                   ing 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 direc-
              tory 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'.

    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 sin-
              gle 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 vari-
              ous 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 any-
              where 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.
