Introduction

This tool is used to generate graphic representation of web pages. It can create bitmap formats such as PNG or JPEG and PDF documents.

Requirements

WebKitTool requires Mac OS X Tiger (v10.4) or later and runs on Intel and PPC Macs.

Installation

WebKitTool consists of a single file which can be installed anywhere, preferably in /usr/local/bin or ~/bin - make sure the file is executable.

Usage

WebKitTool is a command line tool which is invoked like this:

./WebKitTool [OPTIONS] <web address> <output path>

The file extension of the output path defines the output format (pdf, png or jpg).

The general options are:

• -w, --browserwidth

  Specifies the width in pixel of the virtual browser window.

For PDF files, you can use following options:

• -p, --paginage

  Creates multiple pages (A4 format) instead of one big page.

• -o, --orientation

  Sets the page orientation: 'portrait' (default) or 'landscape'.

• --header-left-js, --header-right-js, --footer-left-js, --footer-right-js

  Sets a JavaScript expression to be evaluated for setting header and footer texts. The window object has an additional object called printInfo with the properties currentPage and pageCount.

Examples

Creating a PNG image of www.google.com:

./WebKitTool www.google.com google.png

Creating a single page PDF of www.google.com:

./WebKitTool www.google.com google.pdf

Creating a multipage PDF of www.engadget.com with headers and footers:

./WebKitTool -p \
  --header-left-js document.title \
  --header-right-js "new Date().toLocaleString()" \
  --footer-left-js document.location.href \
  --footer-right-js "'Page ' + window.printInfo.currentPage + ' of ' + window.printInfo.pageCount" \
  http://www.engadget.com engadget.pdf

Additional Information

If a web page you want to capture uses Flash, you might see the following output in the Terminal:

Debugger() was called!

There is nothing to worry about.
