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-caches
39 Discard all caches immediately. They will be re-generated as
40 needed.
41
42 directory-or-URL
43 If a pathname it is the directory tree whose images should be used.
44
45 If a URL is specified, it should be the URL of an RSS or Atom feed
46 containing images. The first time it is accessed, all of the im‐
47 ages in the feed will be downloaded to a local cache directory.
48 The URL will be polled again when the cache times out. Any new im‐
49 ages will be downloaded and cached, and any images no longer in the
50 feed will be discarded.
