In this article, we will see how we can restrict to SVG file version in pycairo using Python.
Pycairo is a Python module providing bindings for the cairo graphics library. This library is used for creating SVG i.e vector files in python. The easiest and quickest way to open an SVG file to view it (read-only) is with a modern web browser like Chrome, Firefox, Edge, or Internet Explorer—nearly all of them should provide some sort of rendering support for the SVG format.
The SVG specification was updated to version 1.1 in 2011. There are two ‘Mobile SVG Profiles,’ SVG Tiny and SVG Basic, meant for mobile devices with reduced computational and display capabilities.
In order to use the we will use restrict_to_version with SVG surface object
Syntax : restrict_to_version()
Argument : It takes SVG version as argument
Return : It returns non
Python3
# importing pycairoimport cairo# getting all the svg versions availableversions = surface.get_versions()# Selecting version from listversion = versions[1]# creating a SVG surface# here geek95 is file name & 700, 700 is dimensionwith cairo.SVGSurface("geek95.svg", 700, 700) as surface: # Restriction to version surface.restrict_to_version(version) # creating a cairo context object context = cairo.Context(surface) # creating a rectangle(square) context.rectangle(10, 10, 100, 100) # setting color of the context context.set_source_rgba(0.4, 1, 0.4, 1) # stroke out the color and width property context.fill()# printingprint("SVG version") |
Output:
SVG version
Note : This function should only be called before any drawing operations have been performed on the given surface. The simplest way to do this is to call this function immediately after creating the surface.
