screenshot.py

Taking a screenshot of a webpage.

screenshot.py is a wrapper script that calls phantomjs and convert to do the real job. The advantage of screenshot.py is its very simple usage.

Usage

• screenshot.py -h

  Help.

• screenshot.py -full http://reddit.com full.jpg

  Screenshot of the entire page (can be very high).

• screenshot.py -window http://reddit.com window.jpg

  Screenshot of the area that you see in the browser.

• screenshot.py -thumb http://reddit.com thumb.jpg

  Thumbnail of the area that you see in the browser.

• Sometimes there is a problem with the JavaScript on the given webpage, which can cause PhantomJS to crash :( In this case disable JS rendering with the --nojs extra option. Then use the script as explained above.

  Example:

  screenshot.py --nojs -thumb http://buggy-js.com thumb.jpg

Customization

Check out the beginning of the source code. You may want to change WIDTH and THUMB_WIDTH.

Requirements

screenshot.py relies on PhantomJS and the command convert. convert is part of the ImageMagick package. See http://phantomjs.org/build.html for more information on how to install PhantomJS. We also need the rasterize.js script that comes with PhantomJS. You can find a copy of it in the assets/ folder. I also put a customized version of the rendering script to the assets/ folder called rasterize-nojs.js that disables JavaScript rendering on the given webpage.
