[reportlab-users] SVG export in comparison to PDF?

[Ilya Flyamer]

PDF weighs 10.5 Mb, SVG file for 10% of that data weighs 17 Mb.

No, I haven't, how do I do that? Where can I find that file?

I use Python 2.7
Bio.__version__  is 1.62b
reportlab.Version is 2.7

No, there were some issues with fonts, but It seems, I successfully solved
them.

Best,
Ilya
