14 The xscreensaver-getimage-file program is a helper program for the
15 xscreensaver hacks that manipulate images. It is invoked by xscreen‐
16 saver-getimage(6x) as needed.
17
18 It prints the name of a randomly-selected image file. The directory is
19 searched recursively. Non-image files and images smaller than 500x500
20 are excluded.
21
22 The directory may also be the URL of an RSS/Atom feed. Enclosed images
23 will be downloaded and cached locally.
24
25 The contents of the directory are cached, for performance. The cache
26 is re-generated if 3 hours have passed.
27
28
30 xscreensaver-getimage-file accepts the following options:
31
32 --verbose
33 Print diagnostics.
34
35 --no-cache
36 Ignore the cache when searching for images. This may be slow.
37
38 --flush-cache
39 Discard all caches immediately. They will be re-generated as
40 needed.
41
42 directory-or-URL
43 If it is a pathname, it will be searched recursively for images.
44
45 If it is a URL, it should be an RSS or Atom feed, or an HTML page
46 whose metadata links to its feed. All of the feed's images will be
47 downloaded to a local cache. The URL will be re-polled periodi‐
48 cally, downloading any new images and removing expired ones.
49
51 Depending on your operating system, the filename cache will be one of:
52
53 $HOME/.cache/xscreensaver/xscreensaver-getimage.cache
54 $HOME/tmp/.xscreensaver-getimage.cache
55 $HOME/.xscreensaver-getimage.cache
56 $HOME/Library/Caches/org.jwz.xscreensaver.getimage.cache
57
58 Images from feeds will be downloaded and cached at one of:
59
60 $HOME/.cache/xscreensaver/SUBDIR/
61 $HOME/tmp/.xscreensaver-feeds/SUBDIR/
62 $HOME/.xscreensaver-feeds/SUBDIR/
63 $HOME/Library/Caches/org.jwz.xscreensaver.feeds/SUBDIR/
