NAME
gifview - displays GIF images and animations on the X window system
SYNOPSIS
gifview
[--displaydisplay]
[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 or n
Go to the next frame.
b or p
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 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).
--title title
Sets the
gifview
window's title. The default is "gifview", followed by information about the
currently displayed file and frame.
-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, -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 colormap
flashing.
--background color
--bg color
Set the background color, which is used
for transparent 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.
