Hi Floris,

directly generating SVG with ConTeXt LMTX is not possible.

But, using LMTX to generate SVGs has some advantages over MPOST.

You can use ConTeXt's advanced color management (transparency and more) and you can use the very nice font management.

So my "metapost" file is:

\startMPpage
% metapostcode
\stopMPpage

To get a nice SVG I used to key:

context metapost.tex

and

mutool convert -o metapost.svg -O text=path metapost.pdf

Hope it helps a little

Greetings Lutz
