CentOS - Aug 2013 - convert webpage to image

What is the easiest way to convert a webpage into a jpg
or png file?  I've seen several programs that can do
various conversions, but nothing open source that can
do it in a single conversion.

Just wondering if anyone on the list has suggestions
for something I can put into a script to convert a
webpage into a file I can use with my screensaver.

Perhaps use one of the PDF printing tools (where you can print to a PDF 
file) and then use convert from ImageMagick to convert the PDF file to a 
graphics format.?

I don't really think this is on topic, but regardless, have a look at
phantomjs' [1] rendering capabilities [2].

JPEG isn't an appropriate format for text. I'm not sure about PNG.

A script? You could easily take a window capture with the Gimp.

I wrote a few lines to do this, but it involves using firefox, and
'import' from ImageMagick.

The first script starts firefox in a virtual frame:

==Xvfb :2 -screen 0 1280x1024x24 > /dev/null 2>&1 &
export DISPLAY=localhost:2.0

firefox http://ip.of.your.page/page.html &
==
Then the second script captures/crops what I want:

==export DISPLAY=localhost:2.0
import -crop '1024x512+54+235' -window root /path/to/result.png
=
You'll have to adjust the crop values to what you want.

This will do exactly what you want without resorting to hackery or using
external services.  It has a component to convert to both pdf or an image
and uses webkit.

The binaries are standalone and require no special dependencies.  The
command line is sensitive to the order you place options, but otherwise it
works very well.
