6 gifview - displays GIF images and animations on the X window system
7
9 gifview [--display display] [options] [filenames and frames]...
10
12 gifview displays GIF image files on workstations and terminals running
13 the X Window System. gifview understands multi-image GIFs, which can
14 be displayed either as slideshows or as animations.
15
17 gifview windows recognize several keystrokes and button commands. Many
18 of them are only useful for multi-image GIFs.
19 Space or n Go to the next frame.
21 b or p Go to the previous frame.
23 r or < Go to the first frame.
25 > Go to the last frame.
27 ESC Stop the animation.
29 s or a Toggle between animation and slideshow mode.
31 u Toggle between normal and unoptimized mode.
33 Backspace Delete this window.
35 q Quit gifview.
37 Left-clicking on a window goes to the next frame; right-clicking on a
39 window deletes that window.

42 gifview's command line consists of GIF input files and options. Most
43 options start with a dash (-) or plus (+); frame selections, a kind of
44 option, start with a number sign (#). Anything else is a GIF input
45 file.
46 gifview displays one window for each GIF input file you specify. If no
48 GIF input file is given, or you give the special filename `-', it reads
49 from the standard input.
50
52 --animate, -a
53 Animate multi-image GIFs by default. Normally, multi-image GIFs
54 first appear in slideshow mode. You can always use the `a' key‐
55 stroke to toggle between modes. This option has a converse,
56 `--no-animate' or `+a'.
57 --unoptimize, -U
59 Display multi-image GIFs as ``unoptimized'', which shows a faith‐
60 ful representation of what a user will see at each frame of an an‐
61 imation. See gifsicle(1) for a more detailed description of unop‐
62 timization. This option has a converse, `--no-unoptimize' or `+U'.
63 GIFs are always displayed unoptimized in animation mode.
64 -d display
66 --display display
67 Sets the X display to display. This option must come before any
68 GIF files.
69 --name name
71 Sets the application name under which resources are found, rather
72 than the default of "gifview". Since gifview itself does not use
73 the resource database, this is mostly useful for communication
74 with your window manager.
75 --geometry geometry
77 Set the size and position of gifview's windows. This is a standard
78 X option. At most one --geometry option can be given per window
79 (that is, per input GIF file).
80 --title title
82 Sets the gifview window's title. The default is "gifview", fol‐
83 lowed by information about the currently displayed file and frame.
84 -w window
86 --window window
87 Display the next GIF input in an existing X window, instead of
88 making a new top-level window. This way, you can use gifview to
89 display animated GIFs in a window you created with another pro‐
90 gram. The window argument should be an integer (gifview will use
91 that window ID) or `root' (gifview will use the root window).
92 --new-window window
94 Display the next GIF input in a new child of an existing X window.
95 This child window will disappear when gifview exits. The window
96 argument should be an integer (gifview will use that window ID) or
97 `root' (gifview will use the root window).
98 --install-colormap, -i
100 Use a private colormap for each window (if you are using a Pseudo‐
101 Color display). This avoids polluting the existing colormap, and
102 may produce better results if your colormap is full, but causes
103 annoying colormap flashing.
104 --background color
106 --bg color
107 Set the background color, which is used for transparent pixels.
108 --min-delay delay
110 Set the minimum delay between frames to delay, which is measured
111 in hundredths of a second. Default is 0.
112 --fallback-delay delay
114 Set the frame delay of GIFs that do not specify a delay value or
115 have a delay of 0. The final value is still subject to the value
116 of --min-delay. Like --min-delay, delay is measured in hundredths
117 of a second. Default is 0.
118 --no-interactive, +e
120 Don't pay attention to mouse buttons or keystrokes.
121 --memory-limitlim
123 Cache at most lim megabytes of images in memory when animating.
124 Default is 40.
125 --help
127 Print usage information and exit.
128 --version
130 Print the version number and some quickie warranty information and
131 exit.
132 Frame Selections
134 A frame selection tells gifview which frame to initially display from
135 the current input file. They are useful only for animations, as non-an‐
136 imated GIFs only have one frame. Frame selections can only be displayed
137 in slideshow mode.
138 #num Select frame num. (The first frame is `#0'. Negative num‐
140 bers count backwards from the last frame, which is `#-1'.)
141 #name Select the frame named name.
142 If you give two or more frame selections, you will get one window per
144 frame selection.
