Re: [Therion] Metapost for sump/syphon hazard symbol

[Martin Sluka via Therion]

It is very simple conversion which don’t use Metapost’s options.  Odesláno z iPhonu 13. 4. 2024 v 8:49, Henry Bennett <he...@hbennett.com>:  if you could get the image into postscript then, you could use http://www.pstoedit.net/ to convert to Metapost. You should be able to get EPS by printing to a Postscript printer and then choosing print to file.
