# webshot: hackish thing to take a picture of a whole webpage. |

# idea from sippey (http://www.sippey.com/2004/blog-snaps/) |

# inspiration from bradfitz |

# usage: webshot url filename |

# - include signal grabbing |
16 |
# - dynamic vncserver display |
17 |
# - correct WindowID parsing |
18 |
# - wait for browser to load full page (useful on slow links) |

# 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=800 |
31 |
H=800 |

|
33 |
# and then resize it to |
34 |
