mozgrab.pl: a web page screen shot grabber using Mozilla
mozgrab.pl is a UNIX command-line utility that can be used to make automated
screen shots of web pages, without web browser menus or other decorations.
The screen shot can be up to 30 pages (32000 pixels) high. It invokes Mozilla
to download and show a web page, and then mozgrab.pl makes screen shots and
concatenates them vertically to form a PPM file.
The newest version of this web page is available from
Developing mozgrab.pl was the homework assignment
of the author
for the ATHENS ENSAM3 course in November 2004.

- can start up Mozilla automatically
- does not grab window manager and browser decorations
- can make the grab taller than a single screen
- web pages taller than 32000 pixels will be cropped (this is an
inherent X11 limitation)
- the amount of time spent waiting for Mozilla to render the pages are
- a running X11 session is required
- two instances of mozgrab.pl cannot run concurrently
- a local copy of Mozilla is required
- Mozilla sometimes fails to render the page (especially the letters) --
mozgrab.pl has to be run again.
