gifview - displays GIF images and animations on the X window system

gifview %[--display display] %[options] %[filenames and frames]...

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.

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.

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.

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, or

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, or GIFs are always displayed unoptimized in animation mode.

Sets the X display to display. This option must come before any GIF files.

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.

Set the size and position of gifview's windows. This is a standard X option. At most one option can be given per window (that is, per input GIF file).

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).

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).

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.

Set the background color, which is used for transparent pixels.

Don't pay attention to mouse buttons or keystrokes.

Print usage information and exit.

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