Importing SVG

[vilim]

There doesn't seem to be a way to import external vector assets and use them with compose. Would it be necessary to write an e.g. SVG to Compose parser to implement this?

[lobingera]

a) there was recently a discussion about a SVG parser on discourse
b) not all SVG elements have counterparts in Compose right now, so some intermediate steps might be needed.
c) with Rsvg+Cairo you could get to a simple CairoScript notation that would be easier to parse (it's a few key words and numbers)

        using Rsvg
        using Cairo
        io = IOBuffer()
        cs = CairoScriptSurface(io,500.0,500.0)
        r = Rsvg.handle_new_from_file("../.julia/dev/Rsvg/data/star.svg")
        c = Cairo.CairoContext(cs)
        Rsvg.handle_render_cairo(c,r)
        seek(io,0)
        println(String(read(io)))

outputs
