Menu
I want to convert following HTML to PNG image in Python.
<html>
<b>Bold text</b>
</html>
This HTML is, of course, an example.
I have tried 'pisa' but it converts html to PDF, not to image. I can convert HTML to PDF and then convert PDF to PNG, but I was wondering if there is any direct solution (i.e HTML to PNG). Any built-in or external module will work nicely.
If this can be done in Graphicsmagick or Imagemagick, then it will be perfect.

webkit2png. The original version is OSX-only, but luckily there is a cross-platform fork: https://github.com/AdamN/python-webkit2png

To expand on vartec's answer to also explain how to use it...
Install webkit2png
The easiest way is probably to simply clone the github repo and run the setup.
mkdir python-webkit2png
git clone https://github.com/adamn/python-webkit2png.git python-webkit2png
python setup.py install
This requires python and git to already be installed. For cygwin, this will add webkit2png as a command to the path. I haven't tested this for other terminals/OS.
Run it
Say you have your website in the current directory. (I had a html file that was using a css stylesheet - but there's no need to think about the css file.)
webkit2png something.html -o something.png
Optionswebkit2png -h informs us:
Options:
--version show program's version number and exit
-h, --help show this help message and exit
-x WIDTH HEIGHT, --xvfb=WIDTH HEIGHT
Start an 'xvfb' instance with the given desktop size.
-g WIDTH HEIGHT, --geometry=WIDTH HEIGHT
Geometry of the virtual browser window (0 means
'autodetect') [default: (0, 0)].
-o FILE, --output=FILE
Write output to FILE instead of STDOUT.
-f FORMAT, --format=FORMAT
Output image format [default: png]
--scale=WIDTH HEIGHT Scale the image to this size
--aspect-ratio=RATIO One of 'ignore', 'keep', 'crop' or 'expand' [default:
none]
-F FEATURE, --feature=FEATURE
Enable additional Webkit features ('javascript',
'plugins')
-c COOKIE, --cookie=COOKIE
Add this cookie. Use multiple times for more cookies.
Specification is value of a Set-Cookie HTTP response
header.
-w SECONDS, --wait=SECONDS
Time to wait after loading before the screenshot is
taken [default: 0]
-t SECONDS, --timeout=SECONDS
Time before the request will be canceled [default: 0]
-W, --window Grab whole window instead of frame (may be required
for plugins)
-T, --transparent Render output on a transparent background (Be sure to
have a transparent background defined in the html)
--style=STYLE Change the Qt look and feel to STYLE (e.G. 'windows').
--encoded-url Treat URL as url-encoded
-d DISPLAY, --display=DISPLAY
Connect to X server at DISPLAY.
--debug Show debugging information.
--log=LOGFILE Select the log output file
Notable options are the setting of width and height.
Troubleshooting
Using cygwin, I encountered webkit2png: cannot connect to X server :0.0.
To fix this (I had already performed export DISPLAY=0.0), I had to start an X-Server. On cygwin, this can be done by running startxwin in a second terminal. Make sure to install it first via the cygwin setup.
