file

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

--ad=file

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

--antialias, --noantialias

Whether to use antialiasing.

--arguments=args

Start ghostscrip with additional options as specified by the string args.

--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.

--fullscreen

Selects the fullscreen mode.

--infoSilent

Do not show any ghostscript messages in an info popup window.

--infoErrors

Only show error messages from ghostscript in an info popup window.

--infoAll

Shows all ghostscript messages in an info popup window.

--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).

--version

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

--help, --usage

Display a short help message and exit.

--scale=n

n must be an integer or a positive float. In case n is an integer, n selects the scale entry n relative to the scale 1.0. With the special value of -1000 Fit to page is selected, and likewise with the value of -1001 Fit widthto page is selected. In case n is a float, n selects an arbitrary scale.

--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.

--orientation=orientation

Sets the orientation. Valid values for orientation are portrait, landscape, seascape and upsidedown.

--quiet, --noquiet

Whether to start ghostscript with the -dQUIET option.

--resize, --noresize

Whether ghostscrip is allowed to automatically fit the size of its window to the size of the displayed page.

--password=PASSWORD

When opening a file, use PASSWORD to decrypt it. This Option is usefull for viewing encrypted PDF files.

--presentation

Is actually a shortcut for --fullscreen --noresize --scale=-1000 --widgetless.

--safer, --nosafer

Whether to start ghostscript in safer mode (that includes he -dSAFER option or the -dDELAYSAFER mode where appropriate) and the -P- option.

--safedir, --nosafedir

Whether to start ghostscript from a safe direcotry or not.

--spartan

This is a shortcut for --style=gv_spartan.dat.

--style=file

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

--widgetless

This is a shortcut for --style=gv_widgetless.dat.
