About

Svglib is an experimental library for reading SVG files and converting them (to a reasonable degree) to other formats using the Open Source ReportLab Toolkit. As a package it reads existing SVG files and returns them converted to ReportLab Drawing objects that can be used in a variety of ReportLab-related contexts, e.g. as Platypus Flowable objects or in RML2PDF. As a command-line tool it converts SVG files into PDF ones.

Tests include a vast amount of tests from the W3C SVG test suite. It also accesses around 200 flags from Wikipedia.org for test purposes (some of them hinting at more work to be done).

This release changes the license from GPL 3 to LGPL 3, introduces tiny bug fix reported by Harald Armin Massa and adapts to changed URLs for Wikipedia SVG flags used for test purposes.

Features

  • convert SVG files into ReportLab Graphics Drawing objects
  • handle plain or compressed SVG files (.svg and .svgz)
  • allow patterns for output files on command-line
  • install a Python package named svglib
  • install a Python command-line script named svg2pdf
  • provide a Unittest test suite
  • test on some standard W3C SVG tests available online
  • test on some Wikipedia sample SVG symbols available online
  • test on some Wikipedia sample SVG flags available online

Examples

You can use svglib as a Python package e.g. like in the following interactive Python session:

>>> from svglib.svglib import svg2rlg
>>> from reportlab.graphics import renderPDF
>>>
>>> drawing = svg2rlg("file.svg")
>>> renderPDF.drawToFile(drawing, "file.pdf")

In addition a script named svg2pdf can be used more easily from the system command-line like this (you can see more examples when typing svg2pdf -h):

$ svg2pdf file1.svg file2.svgz
$ svg2pdf -o "%(basename)s.pdf" /path/file[12].svgz?

Installation

There are two ways to install svglib, depending on whether you have the easy_install command available on your system or not.

1. Using easy_install

With the easy_install command on your system and a working internet connection you can install svglib with only one command in a terminal:

$ easy_install svglib

If the easy_install command is not available to you and you want to install it before installing svglib, you might want to go to the Easy Install homepage and follow the instructions there.

2. Manual installation

Alternatively, you can install the svglib tarball after downloading the file svglib-0.6.3.tar.gz and decompressing it with the following command:

$ tar xfz svglib-0.6.3.tar.gz

Then change into the newly created directory svglib and install svglib by running the following command:

$ python setup.py install

This will install a Python module file named svglib.py in the site-packages subfolder of your Python interpreter and a script tool named svglib in your bin directory, usually in /usr/local/bin.

Dependencies

Svglib depends on the reportlab package, which, as of now, you have to install manually, before you can use svglib. Unfortunately, up to its latest release, reportlab 2.2, this package cannot be installed automatically using easy_install.

Testing

The svglib tarball distribution contains a Unittest test suite in the file test_svglib.py which can be run like shown in the following lines on the system command-line:

$ tar xfz svglib-0.6.3.tar.gz
$ cd svglib/src/test
$ python test_svglib.py
