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 com-
pressed). 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 pri-
ority 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 speci-
fied 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 struc-
ture 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 docu-
ments which import other documents without enclos-
ing them within the proper "BeginDocument" and
"EndDocument" comments. If -eof is used, the scan-
ner 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 suf-
ficiently large pixmap. If -nopixmap is used the X
Server is responsible for maintaining obscured por-
tions of the displayed page (see also the "useBack-
ingPixmap" 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 pri-
ority than those provided in the context of the -ad
<resource file> option.
-swap, -noswap
Whether to interchange the meaning of the orienta-
tions landscape and seascape.
-watch, -nowatch
The -watch option causes gv to check the document
periodically. If changes are detected gv will auto-
matically display the newer version of the file.
The document is by default checked once every sec-
ond. This can be changed via the watchFileFre-
quency resource. Note that sending gv the SIGHUP
signal also causes an update of the displayed docu-
ment. 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" envi-
ronment variable, or, if this variable is not
defined, implementation dependant. In most cases it
is "/usr/X11/lib/X11/app-defaults/GV". Administra-
tors may want to modify this file in order to set
up gv according 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
"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 key-
board 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 use-
ful. In this case gv attempts to allocate a suffi-
ciently 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 inter-
preter.
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 display-
ing a directory contents in the file selection win-
dow. 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", "tog-
gle_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 "auto-
matic" 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.

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 previ-
ous/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 dis-
playing 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 'propor-
tionally'.
- press button 2, move mouse, release button 2
Scrolls a file or directory list 'abso-
lutely'.
- 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 Selec-
tion 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 con-
tents):

- 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 dur-
ing 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 indi-
cates 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

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 corre-
spond 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. Auto-
matic 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. Alterna-
tively 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 inter-
faces that windows are supposed to be scrolled by
means of scrollbars attached to their sides. How-
ever, 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 dis-
played by pressing the "Redisplay" button in the
main window (VMS users should use the "Update File"
entry in the "File" menu). Choosing the "Redis-
play" entry in the menu that pops up when clicking
with the third mouse button anywhere on the dis-
played 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 creat-
ing 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 gen-
erating a postscript file from latex sources the
line
