Async-IMGKit: Python library of HTML to IMG wrapper
===================================================
|Build Status| |Code Coverage| |PyPI version|
Python 3 async wrapper for
`IMGKIT <https://github.com/jarrekk/imgkit>`__.
Installation
------------
1. Install async-imgkit:
.. code:: python
pip install async-imgkit
2. Install wkhtmltopdf:
- Debian/Ubuntu:
.. code:: bash
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 <http://wkhtmltopdf.org/>`__ site or you can use this
`script <https://github.com/jarrekk/imgkit/blob/master/travis/init.sh>`__.
- MacOSX
.. code:: bash
brew install wkhtmltopdf
- Windows and other options: check `wkhtmltopdf
homepage <http://wkhtmltopdf.org/>`__ for binary installers or `wiki
page <https://github.com/pdfkit/pdfkit/wiki/Installing-WKHTMLTOPDF>`__.
Usage
-----
Simple example:
.. code:: python
import async_imgkit.api as imgkit
await imgkit.from_url('http://google.com', 'out.jpg')
await imgkit.from_file('test.html', 'out.jpg')
await imgkit.from_string('Hello!', 'out.jpg')
You can pass a list with multiple URLs or files:
.. code:: python
await imgkit.from_url(['google.com', 'yandex.ru', 'engadget.com'], 'out.jpg')
await imgkit.from_file(['file1.html', 'file2.html'], 'out.jpg')
Also you can pass an opened file:
.. code:: python
with open('file.html') as f:
await imgkit.from_file(f, 'out.jpg')
If you wish to further process generated IMG, you can read it to a
variable:
.. code:: python
# Use False instead of output path to save pdf to a variable
img = await imgkit.from_url('http://google.com', False)
You can find all wkhtmltoimage options by type ``wkhtmltoimage`` command
or visit this
`Manual <http://madalgo.au.dk/~jakobt/wkhtmltoxdoc/wkhtmltoimage_0.10.0_rc2-doc.html>`__.
You can drop '--' in option name. If option without value, use *None,
False* or *''* for dict value:. For repeatable options (incl. allow,
cookie, custom-header, post, postfile, run-script, replace) you may use
a list or a tuple. With option that need multiple values (e.g.
--custom-header Authorization secret) we may use a 2-tuple (see example
below).
.. code:: python
options = {
'format': 'png',
'crop-h': '3',
'crop-w': '3',
'crop-x': '3',
'crop-y': '3',
'encoding': "UTF-8",
'custom-header' : [
('Accept-Encoding', 'gzip')
]
'cookie': [
('cookie-name1', 'cookie-value1'),
('cookie-name2', 'cookie-value2'),
],
'no-outline': None
}
await imgkit.from_url('http://google.com', 'out.png', options=options)
At some headless servers, perhaps you need to install **xvfb**:
.. code:: bash
# at ubuntu server, etc.
sudo apt-get install xvfb
# at centos server, etc.
yum install xorg-x11-server-Xvfb
Then use **IMGKit** with option **xvfb**: ``{"xvfb": ""}``.
By default, IMGKit will show all ``wkhtmltoimage`` output. If you don't
want it, you need to pass ``quiet`` option:
.. code:: python
options = {
'quiet': ''
}
await imgkit.from_url('google.com', 'out.jpg', options=options)
Due to wkhtmltoimage command syntax, **TOC** and **Cover** options must
be specified separately. If you need cover before TOC, use
``cover_first`` option:
.. code:: python
toc = {
'xsl-style-sheet': 'toc.xsl'
}
cover = 'cover.html'
await imgkit.from_file('file.html', options=options, toc=toc, cover=cover)
await imgkit.from_file('file.html', options=options, toc=toc, cover=cover, cover_first=True)
You can specify external CSS files when converting files or strings
using *css* option.
.. code:: python
# Single CSS file
css = 'example.css'
await imgkit.from_file('file.html', options=options, css=css)
# Multiple CSS files
css = ['example.css', 'example2.css']
await imgkit.from_file('file.html', options=options, css=css)
You can also pass any options through meta tags in your HTML:
.. code:: python
body = """
<html>
<head>
<meta name="imgkit-format" content="png"/>
<meta name="imgkit-orientation" content="Landscape"/>
</head>
Hello World!
</html>
"""
await imgkit.from_string(body, 'out.png')
Configuration
-------------
Each API call takes an optional config paramater. This should be an
instance of ``async_imgkit.api.config()`` API call. It takes the config
options as initial paramaters. The available options are:
- ``wkhtmltoimage`` - the location of the ``wkhtmltoimage`` binary. By
default ``async_imgkit`` will attempt to locate this using
which\ ``(on UNIX type systems) or where`` (on Windows).
- ``meta_tag_prefix`` - the prefix for ``async_imgkit`` specific meta
tags - by default this is ``imgkit-``
Example - for when ``wkhtmltopdf`` is not in ``$PATH``:
.. code:: python
config = imgkit.config(wkhtmltoimage='/opt/bin/wkhtmltoimage')
await imgkit.from_string(html_string, output_file, config=config)
Troubleshooting
---------------
- ``IOError: 'No wkhtmltopdf executable found'``:
Make sure that you have wkhtmltoimage in your ``$PATH`` or set via
custom configuration (see preceding section). *where wkhtmltoimage* in
Windows or *which wkhtmltoimage* on Linux should return actual path to
binary.
- ``IOError: 'Command Failed'``:
This error means that IMGKit 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 wkhtmltoimage versions this can be cause by
segmentation faults)
