Svglib is a pure-Python library for reading SVG files and converting
them (to a reasonable degree) to other formats using the ReportLab Open
Source toolkit.
Used as a package you can read existing SVG files and convert them into
ReportLab Drawing objects that can be used in a variety of contexts,
e.g. as ReportLab Platypus Flowable objects or in RML.
As a command-line tool it converts SVG files into PDF ones (but adding
other output formats like bitmap or EPS is really easy and will be better
supported, soon).
Tests include a huge W3C SVG test suite plus ca. 200 flags from Wikipedia and some selected symbols from Wikipedia (with increasingly less pointing to missing features).
This release introduces many contributions by Claude Paroz, who stepped forward to give this project a long needed overhaul after ca. six years of taking a nap, for which I'm really very grateful! Thanks, Claude!
Previous versions were hosted at https://bitbucket.org/deeplook/svglib.
- convert SVG files into ReportLab Graphics
Drawingobjects - 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 PyTest test suite with over 90% code coverage
- test entire W3C SVG test suite after pulling from the internet
- test all SVG flags from Wikipedia after pulling from the internet
- test selected SVG symbols from Wikipedia after pulling from the net
- run on Python 2.7 and Python 3.5, 3.6 and 3.7
- support for stylesheets is still experimental. Please report any bug or shortcoming on the svglib issue tracker.
- clipping is limited to single paths, no mask support
- color gradients are not supported
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, renderPM
>>>
>>> drawing = svg2rlg("file.svg")
>>> renderPDF.drawToFile(drawing, "file.pdf")
>>> renderPM.drawToFile(drawing, "file.png", fmt="PNG")
Note that the second parameter of drawToFile can be any
Python file object, like a BytesIO buffer if you don't want the result
to be written on disk for example.
In addition a script named svg2pdf can be used more easily from
the system command-line. Here is the output from svg2pdf -h:
usage: svg2pdf [-h] [-v] [-o PATH_PAT] [PATH [PATH ...]]
svg2pdf v. 0.9.0
A converter from SVG to PDF (via ReportLab Graphics)
positional arguments:
PATH Input SVG file path with extension .svg or .svgz.
optional arguments:
-h, --help show this help message and exit
-v, --version Print version number and exit.
-o PATH_PAT, --output PATH_PAT
Set output path (incl. the placeholders: dirname,
basename,base, ext, now) in both, %(name)s and {name}
notations.
examples:
# convert path/file.svg to path/file.pdf
svg2pdf path/file.svg
# convert file1.svg to file1.pdf and file2.svgz to file2.pdf
svg2pdf file1.svg file2.svgz
# convert file.svg to out.pdf
svg2pdf -o out.pdf file.svg
# convert all SVG files in path/ to PDF files with names like:
# path/file1.svg -> file1.pdf
svg2pdf -o "%(base)s.pdf" path/file*.svg
# like before but with timestamp in the PDF files:
# path/file1.svg -> path/out-12-58-36-file1.pdf
svg2pdf -o {{dirname}}/out-{{now.hour}}-{{now.minute}}-{{now.second}}-%(base)s.pdf path/file*.svg

Svglib depends mainly on the reportlab package, which provides
the abstractions for building complex Drawings which it can render
into different fileformats, including PDF, EPS, SVG and various bitmaps
ones. Other dependancies are lxml which is used in the context of SVG
CSS stylesheets.
There are three ways to install svglib.
With the pip command on your system and a working internet
connection you can install the newest version of svglib with only
one command in a terminal:
$ pip install svglib
You can also use pip to install the very latest version of the
repository from GitHub, but then you won't be able to conveniently
run the test suite:
$ pip install git+https://github.com/deeplook/svglib
If you use Anaconda or Miniconda you are surely using its respective package
manager, Conda, as well. In that case you should be able to install svglib
using these simple commands:
$ conda config --add channels conda-forge $ conda install svglib
Svglib was kindly packaged for conda by nicoddemus. See here more about
svglib with conda.
Alternatively, you can install a tarball like svglib-0.9.0.tar.gz
after downloading it from the svglib page on PyPI or the
svglib releases page on GitHub and executing a sequence of commands
like shown here:
$ tar xfz svglib-0.9.0.tar.gz $ cs svglib-0.9.0 $ python setup.py install
This will install a Python package named svglib in the
site-packages subfolder of your Python installation and a script
tool named svg2pdf in your bin directory, e.g. in
/usr/local/bin.
The svglib tarball distribution contains a PyTest test suite
in the tests directory. There, in tests/README.rst, you can
also read more about testing. You can run the testsuite e.g. like
shown in the following lines on the command-line:
$ tar xfz svglib-0.9.0.tar.gz $ cd svglib-0.9.0 $ PYTHONPATH=. py.test ======================== test session starts ========================= platform darwin -- Python 3.5.2, pytest-3.0.5, py-1.4.32, pluggy-0.4.0 rootdir: /Users/dinu/repos/github/deeplook/svglib, inifile: plugins: cov-2.4.0 collected 36 items tests/test_basic.py ............................ tests/test_samples.py .s.s.s.s =============== 32 passed, 4 skipped in 49.18 seconds ================
Please report bugs on the svglib issue tracker on GitHub (pull
requests are also appreciated)!
If necessary, please include information about the operating system, as
well as the versions of svglib, ReportLab and Python being used!
