Render SVG from file to Cairo canvas in Julia

Is there a way to load an SVG from file and then render it to a Cairo canvas? Ideally something like:

image = read_from_svg("my.svg")
set_source_surface(cr, image, 0, 0)
paint(cr)

There is the Rsvg.jl package that wraps the rsvg library. The package can be installed with Pkg.add("Rsvg"). You might have to troubleshoot the installation of the native Cairo and Rsvg libraries -- the package will attempt to do this automatically, but it is a difficult problem based on the multitude of different configurations.

Using that package, it seems be possible to do what you want. From the package's README:

using Rsvg
using Cairo

filename_in = "a4.svg"

r = Rsvg.handle_new_from_file(filename_in);
d = Rsvg.handle_get_dimensions(r);
cs = Cairo.CairoImageSurface(d.width,d.height,Cairo.FORMAT_ARGB32);
c = Cairo.CairoContext(cs);
Rsvg.handle_render_cairo(c,r);
