NAME

SYNOPSIS

DESCRIPTION

INTERACTION

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 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.

--min-delay delay

Set the minimum delay between frames to delay, which is measured in hundredths of a second. Default is 0.

--fallback-delay delay

Set the frame delay of GIFs that do not specify a delay value or have a delay of 0. The final value is still subject to the value of --min-delay. Like --min-delay, delay is measured in hundredths of a second. Default is 0.

--no-interactive, +e

Don't pay attention to mouse buttons or keystrokes.

--memory-limitlim

Cache at most lim megabytes of images in memory when animating. Default is 40.

--help

Print usage information and exit.

--version

Print the version number and some quickie warranty information and exit.
