The webcollage program pulls random image off of the World Wide Web
and scatters them on the root window. One satisfied customer described it
as "a nonstop pop culture brainbath." 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
webcollage is written in
and requires Perl 5.
accepts the following options:
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 seconds.
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:
When drawing on the root window, it always uses the default colormap.
This is actually a limitation of xv. But regardless, when using this
program with xscreensaver, it must be given the default-n
visual specification (see the
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.
