A Python library to create SVG drawings.
|
||
|
|
|
||
|
|
SVG is a language for describing two-dimensional graphics in XML. SVG allows
|
||
|
|
for three types of graphic objects: vector graphic shapes (e.g., paths
|
||
|
|
consisting of straight lines and curves), images and text. Graphical objects
|
||
|
|
can be grouped, styled, transformed and composed into previously rendered
|
||
|
|
objects. The feature set includes nested transformations, clipping paths,
|
||
|
|
alpha masks, filter effects and template objects.
|
||
|
|
|
||
|
|
SVG drawings can be interactive and dynamic. Animations can be defined and
|
||
|
|
triggered either declarative (i.e., by embedding SVG animation elements in
|
||
|
|
SVG content) or via scripting.
|
||
|
|
|
||
|
|
.. seealso:: http://www.w3.org/TR/SVG11/intro.html#AboutSVG
|
||
|
|
|
||
|
|
a simple example::
|
||
|
|
|
||
|
|
import svgwrite
|
||
|
|
|
||
|
|
dwg = svgwrite.Drawing('test.svg', profile='tiny')
|
||
|
|
dwg.add(dwg.line((0, 0), (10, 0), stroke=svgwrite.rgb(10, 10, 16, '%')))
|
||
|
|
dwg.add(dwg.text('Test', insert=(0, 0.2)))
|
||
|
|
dwg.save()
|
||
|
|
|
||
|
|
SVG Version
|
||
|
|
-----------
|
||
|
|
|
||
|
|
You can only create two types of SVG drawings:
|
||
|
|
|
||
|
|
* *SVG 1.2 Tiny Profile*, use Drawing(profile= ``'tiny'``)
|
||
|
|
* *SVG 1.1 Full Profile*, use Drawing(profile= ``'full'``)
