SVGFace error

[biofilos]

I am trying to replicate the procedure posted here (https://groups.google.com/forum/#!topic/etetoolkit/rPNdMWzCirk), but I get the error ` from ete3 import Tree, SVGFace t = Tree("((A, B), (C, D));") f = SVGFace("svg.svg", width=10) f2 = SVGFace("svg.svg", height=10) f3 = SVGFace("svg.svg", height=20, width=10)

If I change my environment from anaconda (which I used for the example above) to virtualenv (Python 3.6.4), the image is generated, but the svg is still rendered as a bitmap

Yes, that's a limitation of the SVG redering options in Qt. I am not sure if there is any easy way to solve it...

Hi Guys,

I am having the same issue. I'm working with anaconda 4.3 on Windows 10. Switching to a virtual env based on python 3.6.4 as the original poster suggests did not fix my issue.:

I have now also tested the SVGFace function on my virtual machine running Ubuntu - with the same results. SVG rendering is a great additon to the ete3 framework and would be useful to me so I hope we can find a solution to this problem. Thanks for your help.
