Generating PDFs from SVG input

Solution 1:

Have you considered svglib?

It looks quite promising, especially as reportlab is the featured pdf tool in Django's docs.

from svglib.svglib import svg2rlg
from reportlab.graphics import renderPDF

drawing = svg2rlg("file.svg")
renderPDF.drawToFile(drawing, "file.pdf")

Solution 2:

Yes, I would also suggest using svglib and the reportlab library for this task although there is very little documentation of the svglib library. I would actually suggest doing the following in your Django view:

from svglib.svglib import SvgRenderer
from reportlab.graphics import renderPDF
import xml.dom.minidom
@csrf_exempt
def export_svg(request):
    # Get data from client side via POST variables
    svg = request.POST.get("svg")
    doc = xml.dom.minidom.parseString(svg.encode( "utf-8" ))
    svg = doc.documentElement
    # Create new instance of SvgRenderer class
    svgRenderer = SvgRenderer()
    svgRenderer.render(svg)
    drawing = svgRenderer.finish()

    # Instead of outputting to a file, we simple return
    # the data and let the user download to their machine
    pdf = renderPDF.drawToString(drawing)
    response = HttpResponse(mimetype='application/pdf')
    response.write(pdf)     

    # If one were to remove the 'attachment; ' from this line
    # it would simple invoke the browsers default PDF plugin
    response["Content-Disposition"]= "attachment; filename=converted.pdf"
    return response

This way you never need to save a temporary file on the server for the user to just download locally anyway. The svglib example that is given requires providing a path to a file... but why not just provide the file itself?

I have documented the steps I have taken using Django and the Raphael SVG library here.

My answer may help someone on macOS:

I user CairoSVG

Firstly, install it with:

pip install cairosvg

Then you can use it in Python:

>>> import cairosvg
>>> cairosvg.svg2pdf(url='image.svg', write_to='image.pdf')

from its documentation:

on macOS, you’ll have to install cairo and libffi (with Homebrew for example)

Solution 4:

You will need to add "import string" for version 0.6.3 to work with python 2.7.

you can use my frok until the pypy is updated.

pip install git+git://github.com/ddehghan/libsvg.git
