- The _\bw_\be_\bb_\bc_\bo_\bl_\bl_\ba_\bg_\be program pulls random image off of the World
- Wide Web and scatters them on the root window. It finds
- these images by doing random web searches, and extracting
- images from the returned pages. It places the images on
- the root window by using the x\bxv\bv(1), g\bgi\bif\bft\bto\bop\bpn\bnm\bm(1), and
- d\bdj\bjp\bpe\beg\bg(1) tools.
-
- _\bw_\be_\bb_\bc_\bo_\bl_\bl_\ba_\bg_\be also works as a CGI program: simply make a sym-
- bolic link to the _\bw_\be_\bb_\bc_\bo_\bl_\bl_\ba_\bg_\be executable called _\bn_\bp_\bh_\b-_\bw_\be_\bb_\bc_\bo_\bl_\b-
- _\bl_\ba_\bg_\be_\b._\bc_\bg_\bi. If this program sees that it is being run as a
- CGI, then it will behave appropriately. (The generated
- web page will list the images one after another, rather
- than tiling them together.)
-
- _\bw_\be_\bb_\bc_\bo_\bl_\bl_\ba_\bg_\be is written in p\bpe\ber\brl\bl(1) and requires Perl 5.
-
-O\bOP\bPT\bTI\bIO\bON\bNS\bS
- _\bw_\be_\bb_\bc_\bo_\bl_\bl_\ba_\bg_\be accepts the following options:
-
- -\b-r\bro\boo\bot\bt Draw on the root window. This option is mandi-
- tory: drawing to a window other than the root win-
- dow is not yet supported.
-
- -\b-v\bve\ber\brb\bbo\bos\bse\be or -\b-v\bv
- Print diagnostics to stderr. Multiple _\b-_\bv switches
- increase the amount of output. _\b-_\bv will print out
- only the URLs of the images; _\b-_\bv_\bv will print all
- the commands being run; and _\b-_\bv_\bv_\bv will print more
- than you care about.
-
- -\b-d\bde\bel\bla\bay\by _\bs_\be_\bc_\bo_\bn_\bd_\bs
- How long to sleep between images. Default 1 sec-
- ond. (Remember that this program probably spends
- a lot of time waiting for the network.)
-
- -\b-b\bba\bac\bck\bkg\bgr\bro\bou\bun\bnd\bd _\bc_\bo_\bl_\bo_\br_\b-_\bo_\br_\b-_\bp_\bp_\bm
- What to use for the background onto which images
- are pasted. This may be a color name, a hexadeci-
- mal RGB specification in the form '#rrggbb', or
- the name of a PPM file.
-
- -\b-t\bti\bim\bme\beo\bou\but\bt _\bs_\be_\bc_\bo_\bn_\bd_\bs
- How long to wait for a URL to complete before giv-
- ing up on it and moving on to the next one.

- Default 30 seconds.
-
- -\b-f\bfi\bil\blt\bte\ber\br _\bc_\bo_\bm_\bm_\ba_\bn_\bd
- 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'
-
-
- -\b-f\bfi\bil\blt\bte\ber\br2\b2 _\bc_\bo_\bm_\bm_\ba_\bn_\bd
- Filter the _\bc_\bo_\bm_\bp_\bo_\bs_\bi_\bt_\be image through this command.
- The _\b-_\bf_\bi_\bl_\bt_\be_\br option applies to the sub-images; the
- _\b-_\bf_\bi_\bl_\bt_\be_\br_\b2 applies to the final, full-screen image.

- 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 d\bde\bef\bfa\bau\bul\blt\bt-\b-n\bn visual specification (see
- the x\bxs\bsc\bcr\bre\bee\ben\bns\bsa\bav\bve\ber\br(1) manual for more details.)
-
- Only the GIF and JPEG image formats are supported.
-
- Transparent and animating GIFs are not supported.

- It's slow.
