webcollage - decorate the screen with random images from the
webcollage [-display host:display.screen] [-root] [-verbose]
[-delay secs] [-timeout secs] [-background bg] [-filter com-
mand] [-filter2 command] [-http-proxy host[:port]]
The webcollage program pulls random image off of the World
Wide Web and scatters them on the root window. One satis-
fied customer described it as "a nonstop pop culture brain-
bath." This program finds its images by doing random web
searches, and extracting images from the returned pages. It
places the images on the root window by using the gif-
topnm(1), djpeg(1), and xli(1), xv(1), or xloadimage(1)
webcollage is written in perl(1) and requires Perl 5.
webcollage accepts the following options:
-root Draw on the root window. This option is manditory:
drawing to a window other than the root window is
not yet supported.
-verbose or -v
Print diagnostics to stderr. Multiple -v switches
increase the amount of output. -v will print out
only the URLs of the images; -vv will print all the
commands being run; and -vvv will print more than
you care about.
How long to sleep between images. Default 1 second.
(Remember that this program probably spends a lot of
time waiting for the network.)
What to use for the background onto which images are
pasted. This may be a color name, a hexadecimal RGB
specification in the form '#rrggbb', or the name of
a PPM file.
How long to wait for a URL to complete before giving
up on it and moving on to the next one. Default 30
Filter all source images through this command. The
command must take a PPM file on stdin, and write a
new PPM file to stdout. One good choice for a
filter would be:
webcollage -root -filter 'vidwhacker -stdin -stdout'
Filter the composite image through this command.
The -filter option applies to the sub-images; the
-filter2 applies to the final, full-screen image.
If you must go through a proxy to connect to the
web, you can specify it with this option, or with
the $http_proxy or $HTTP_PROXY environment vari-
DISPLAY to get the default host and display number.
to get the name of a resource file that overrides
the global resources stored in the RESOURCE_MANAGER
http_proxy or HTTP_PROXY
to get the default HTTP proxy host and port.
FILES AND URLS
/usr/dict/words or /usr/share/lib/dict/words
To find the random words to feed to search engines.
To find random web pages.
When drawing on the root window, it always uses the default
colormap. This is actually a limitation of xv. But regard-
less, when using this program with xscreensaver, it must be
given the default-n visual specification (see the xscreen-
saver(1) manual for more details.)
Only the GIF and JPEG image formats are supported.
Transparent and animating GIFs are not supported.
Too many of the images that it finds are text, not pictures.
This is because most of the web is pictures of text. Which
is pretty sad.
