15 Loads a random sequence of images and smoothly scans and zooms around
16 in each, fading from pan to pan.
17 This program requires a good video card capable of supporting large
19 textures.
20 To specify the directory that images are loaded from, run xscreen‐
22 saver-settings(1) and click on the "Advanced" tab.
23
25 --visual visual
26 Specify which visual to use. Legal values are the name of a
27 visual class, or the id number (decimal or hex) of a specific
28 visual.
29 --window
31 Draw on a newly-created window. This is the default.
32 --root Draw on the root window.
34 --window-id number
36 Draw on the specified window.
37 --duration seconds
39 How long each image will be displayed before loading a new one.
40 Default 30 seconds.
41 --pan seconds
43 How long each pan-and-zoom should last. Default 6 seconds.
44 With the default settings of --pan 6 --duration 30, each image
46 will be displayed five times (30/6), and then a new image will
47 be loaded. If you want a new image to be loaded at each fade,
48 then set --pan and --duration to the same value.
49 --fade seconds
51 How long each cross-fade between images should last. Default 2
52 seconds. If set to 0, then no cross-fading will be done (all
53 transitions will be jump-cuts.)
54 Note that fades are included in the pan time, so --fade cannot
56 be larger than --pan.
57 --zoom number
59 Amount to zoom and pan as a percentage. Default: 75, meaning
60 that 75% or more of each image will always be visible. If set
61 to 100%, then the images will always fill the screen, and no
62 panning or zooming will occur. (Images will still smoothly
63 fade from one to another if --fade is non-zero.)
64 --titles
66 Whether to print the file name of the current image in the up‐
67 per left corner.
68 --letterbox
70 In "letterbox" mode, when an image is not the same aspect ratio
71 as the screen, black bars will appear at the top/bottom or
72 left/right so that the whole image can be displayed. This is
73 the default.
74 --clip In "clip" mode, when an image is not the same aspect ratio as
76 the screen, we will zoom in further until the image takes up
77 the whole screen. This is the opposite of --letterbox.
78 --delay number
80 Per-frame delay, in microseconds. Default: 20000 (0.02 sec‐
81 onds.).
82 --fps Display the current frame rate, CPU load, and polygon count.
84 --cutoff number
86 If the frame rate we are achieving is lower than this, then
87 panning, fading, and zooming will be disabled. Default 5 FPS.
88 The idea here is that if your machine can't maintain a decent
90 frame rate, then it must not have fast 3D hardware, so we might
91 as well behave in a simpler manner. Set this to 0 to disable
92 this check.
93 --debug Prints debugging info to stderr.
95 --wireframe
97 Another debug mode.
98
100 DISPLAY to get the default host and display number.
101 XENVIRONMENT
103 to get the name of a resource file that overrides the global
104 resources stored in the RESOURCE_MANAGER property.
105 XSCREENSAVER_WINDOW
107 The window ID to use with --root.
