8 The \fIxscreensaver\-getimage\fP program is a helper program for the
9 xscreensaver hacks that manipulate images. This is not a user-level
12 This program selects a random image, and puts it on the specified
13 window. This image might be a snapshot of the desktop; or a frame
14 captured from the system's video input; or a randomly-selected image
17 .I xscreensaver-getimage
18 reads the \fI~/.xscreensaver\fP file for configuration information.
19 It uses these settings:
22 Whether it is acceptable to grab snapshots of the desktop.
23 The security paranoid might want to turn this off, to avoid letting
24 people see (but not touch!) your desktop while the screen is locked.
27 Whether it is acceptable to grab frames of video from the system's video
28 input. Grabbing of video is done by invoking the
29 .BR xscreensaver-getimage-video (1)
33 Whether it is acceptable to display random images found on disk.
34 Selection and loading of images is done by invoking the
35 .BR xscreensaver-getimage-file (1)
39 When loading images from disk, this is the directory to search.
40 The directory will be searched recursively, and all files in it are
43 If none of the three options are set to True, then video
44 colorbars will be displayed instead.
46 If the target window is not the root window, then this program
47 will \fIalways\fP grab a desktop image. This means that if an
48 image-manipulating xscreensaver mode is run in a normal window,
49 it will always operate on a desktop image; it's only when it is
50 run in \fI-root\fP mode (or when invoked by xscreensaver) that
51 it will load image files or grab video.
