capturing

3 # This script is based on work of mendel from
4 # http://www.lafferty.ca/software/webshots/webshot
5 # webshot: hackish thing to take a picture of a whole webpage.
6 #
7 # idea from sippey (http://www.sippey.com/2004/blog-snaps/)
8 # inspiration from bradfitz
9 #
10 # usage: webshot url filename
11 #
12 # JPEG seems to be the best format.

14 # Modified by Dobrica Pavlinusic 2004-07-25
15 # - include signal grabbing
16 # - dynamic vncserver display
17 # - correct WindowID parsing
18 # - wait for browser to load full page (useful on slow links)
19 #
20 # It will need follwing external utilities:
21 # vncserver
22 # mozilla-firefox
23 # HEAD (part or LWP perl library, it can be commented out)
24 # nc (netcat, to simulate web server)
25 # xwininfo (standard part of X-clients)
26 # xwit (not so standard command, but very useful)
27 # import (part of ImageMagick package)
28 #
29 # It will create snapshot of following size
30 W=1024
31 H=768

33 # and then resize it to (comment out to disable)
