GIFVIEW(1)GIFVIEW(1)NAMEgifview - displays GIF images and animations on the X win-
dow system
SYNOPSISgifview [--display display] [options] [filenames and
frames]...
DESCRIPTIONgifview displays GIF image files on workstations and ter-
minals running the X Window System. gifview understands
multi-image GIFs, which can be displayed either as
slideshows or as animations.
INTERACTIONgifview windows recognize several keystrokes and button
commands. Many of them are only useful for multi-image
GIFs.
Space Go to the next frame.
b Go to the previous frame.
r or < Go to the first frame.
> Go to the last frame.
ESC Stop the animation.
s or a Toggle between animation and slideshow mode.
u Toggle between normal and unoptimized mode.
Backspace Delete this window.
q Quit gifview.
Left-clicking on a window goes to the next frame; right-
clicking on a window deletes that window.
COMMAND LINE
gifview's command line consists of GIF input files and
options. Most options start with a dash (-) or plus (+);
frame selections, a kind of option, start with a number
sign (#). Anything else is a GIF input file.
gifview displays one window for each GIF input file you
specify. If no GIF input file is given, or you give the
special filename `-', it reads from the standard input.
OPTIONS--animate, -a
Animate multi-image GIFs by default. Normally, multi-
image GIFs first appear in slideshow mode. You can
always use the `a' keystroke to toggle between modes.
This option has a converse, `--no-animate' or `+a'.
--unoptimize, -U
Display multi-image GIFs as ``unoptimized'', which
shows a faithful representation of what a user will
see at each frame of an animation. See gifsicle(1)
for a more detailed description of unoptimization.
This option has a converse, `--no-unoptimize' or
`+U'. GIFs are always displayed unoptimized in ani-
mation mode.
-d display
--display display
Sets the X display to display. This option must come
before any GIF files.
--name name
Sets the application name under which resources are
found, rather than the default of ``gifview''. Since
gifview itself does not use the resource database,
this is mostly useful for communication with your
window manager.
--geometry geometry
Set the size and position of gifview's windows. This
is a standard X option. At most one --geometry option
can be given per window (that is, per input GIF
file).
-w window
--window window
Display the next GIF input in an existing X window,
instead of making a new top-level window. This way,
you can use gifview to display animated GIFs in a
window you created with another program. The window
argument should be an integer (gifview will use that
window ID) or `root' (gifview will use the root win-
dow).
--new-window window
Display the next GIF input in a new child of an
existing X window. This child window will disappear
when gifview exits. The window argument should be an
integer (gifview will use that window ID) or `root'
(gifview will use the root window).
--install-colormap, -i
Use a private colormap for each window (if you are
using a PseudoColor display). This avoids polluting
the existing colormap, and may produce better results
if your colormap is full, but causes annoying col-
ormap flashing.
--background color
--bg color
Set the background color, which is used for transpar-
ent pixels.
--no-interactive, +e
Don't pay attention to mouse buttons or keystrokes.
--help
Print usage information and exit.
--version
Print the version number and some quickie warranty
information and exit.
Frame Selections
A frame selection tells gifview which frame to initially
display from the current input file. They are useful only
for animations, as non-animated GIFs only have one frame.
Frame selections can only be displayed in slideshow mode.
#num Select frame num. (The first frame is `#0'.
Negative numbers count backwards from the
last frame, which is `#-1'.)
#name Select the frame named name.
If you give two or more frame selections, you will get one
window per frame selection.
