14 The xscreensaver-getimage program is a helper program for the xscreen‐
15 saver hacks that manipulate images.
16
17 This program selects a random image, and puts it on the specified win‐
18 dow or pixmap. This image might be a snapshot of the desktop; or a
19 frame captured from the system's video input; or a randomly-selected
20 image from disk.
21
22 If only a window ID is specified, the image will be painted there. If
23 both a window ID and a pixmap ID are specified, then the image will be
24 painted on the pixmap; and the window may be modified as a side-effect.
25
27 xscreensaver-getimage reads the ~/.xscreensaver file for configuration
28 information. It uses these settings:
29
30 grabDesktopImages
31 Whether it is acceptable to grab snapshots of the desktop. The se‐
32 curity paranoid might want to turn this off, to avoid letting peo‐
33 ple see (but not touch!) your desktop while the screen is locked.
34
35 grabVideoFrames
36 Whether it is acceptable to grab frames of video from the system's
37 video input. Grabbing of video is done by invoking the xscreen‐
38 saver-getimage-video(6x) program.
39
40 chooseRandomImages
41 Whether it is acceptable to display random images found on disk.
42 Selection and loading of images is done by invoking the xscreen‐
43 saver-getimage-file(6x) program.
44
45 imageDirectory
46 When loading images from disk, this is the directory to find them
47 in. The directory will be searched recursively for images.
48
49 It may also be the URL of an RSS or Atom feed, in which case a ran‐
50 dom image from that feed will be selected instead. The contents of
51 the feed will be cached locally and refreshed periodically as
52 needed.
53
54 If none of the three options are set to True, then video colorbars will
55 be displayed instead.
56
58 When grabbing desktop images, the window argument will be unmapped and
59 have its contents modified, causing flicker. (This does not happen
60 when loading image files or video frames.)
