GIFVIEW(1) General Commands Manual GIFVIEW(1)
NAME
gifview - displays GIF images and animations on the X window system
SYNOPSIS
gifview [--display display] [options] [filenames and frames]...
DESCRIPTION
gifview displays GIF image files on workstations and terminals running the X Window System. gifview understands multi-image GIFs, which
can be displayed either as slideshows or as animations.
INTERACTION
gifview 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 , ]
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 , ]
Display multi-image GIFs as ``unoptimized'', which shows a faithful representation of what a user will see at each frame of an anima-
tion. 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 animation 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 window).
--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 , ]
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 colormap flashing.
--background color
--bg color
Set the background color, which is used for transparent pixels.
[--no-interactive , ]
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.
