Wkhtmltopdf python wrapper to convert html to pdf using the webkit rendering engine and qt
Project description
Python 2 and 3 wrapper for wkhtmltopdf utility to convert HTML to PDF using Webkit.
This is adapted version of ruby PDFKit library, so big thanks to them!
Installation
Install python-pdfkit:
$ pip install pdfkit
Install wkhtmltopdf:
Debian/Ubuntu:
$ sudo apt-get install wkhtmltopdf
Warning! Version in debian/ubuntu repos have reduced functionality (because it compiled without the wkhtmltopdf QT patches), such as adding outlines, headers, footers, TOC etc. To use this options you should install static binary from wkhtmltopdf site or you can use this script.
Windows and other options: check wkhtmltopdf homepage for binary installers
Usage
For simple tasks:
import pdfkit
pdfkit.from_url('http://google.com', 'out.pdf')
pdfkit.from_file('test.html', 'out.pdf')
pdfkit.from_string('Hello!', 'out.pdf')
You can pass a list with multiple URLs or files:
pdfkit.from_url(['google.com', 'yandex.ru', 'engadget.com'], 'out.pdf') pdfkit.from_file(['file1.html', 'file2.html'], 'out.pdf')
Also you can pass an opened file:
with open('file.html') as f:
pdfkit.from_file(f, 'out.pdf')
If you wish to further process generated PDF, you can read it to a variable:
# Use False instead of output path to save pdf to a variable
pdf = pdfkit.from_url('http://google.com', False)
You can specify all wkhtmltopdf options. You can drop ‘–’ in option name. If option without value, use None, False or ‘’ for dict value:
options = {
'page-size': 'Letter',
'margin-top': '0.75in',
'margin-right': '0.75in',
'margin-bottom': '0.75in',
'margin-left': '0.75in',
'encoding': "UTF-8",
'no-outline': None
}
pdfkit.from_url('http://google.com', 'out.pdf', options=options)
By default, PDFKit will show all wkhtmltopdf output. If you dont want it, you need to pass quiet option:
options = {
'quiet': ''
}
pdfkit.from_url('google.com', 'out.pdf', options=options)
Due to wkhtmltopdf command syntax, TOC and Cover options must be specified separately:
toc = {
'xsl-style-sheet': 'toc.xsl'
}
cover = 'cover.html'
pdfkit.from_file('file.html', options=options, toc=toc, cover=cover)
You can specify external CSS file when converting files or strings using css option.
Warning This is a workaround for this bug in wkhtmltopdf. You should try –user-style-sheet option first.
css = 'example.css'
pdfkit.from_file('file.html', options=options, css=css)
You can also pass any options through meta tags in your HTML:
body = """
<html>
<head>
<meta name="pdfkit-page-size" content="Legal"/>
<meta name="pdfkit-orientation" content="Landscape"/>
</head>
Hello World!
</html>
"""
pdfkit.from_string(body, 'out.pdf') #with --page-size=Legal and --orientation=Landscape
Configuration
Each API call takes an optional configuration paramater. This should be an instance of pdfkit.configuration() API call. It takes the configuration options as initial paramaters. The available options are:
wkhtmltopdf - the location of the wkhtmltopdf binary. By default pdfkit will attempt to locate this using which (on UNIX type systems) or where (on Windows).
meta_tag_prefix - the prefix for pdfkit specific meta tags - by default this is pdfkit-
Example - for when wkhtmltopdf is not on $PATH:
config = pdfkit.configuration(wkhtmltopdf='/opt/bin/wkhtmltopdf')) pdfkit.from_string(html_string, output_file, configuration=config)
Troubleshooting
IOError: 'No wkhtmltopdf executable found':
Make sure that you have wkhtmltopdf in your $PATH or set via custom configuration (see preceding section). where wkhtmltopdf in Windows or which wkhtmltopdf on Linux should return actual path to binary.
IOError: 'Command Failed'
This error means that PDFKit was unable to process an input. You can try to directly run a command from error message and see what error caused failure (on some wkhtmltopdf versions this can be cause by segmentation faults)
