[NTG-context] Filter Module with Openscad

26 Apr 2023

      I am using OpenSCAD to create drawings with the filter module with the
following MWE:

\usemodule[filter]
\defineexternalfilter[openscad]
  [filtercommand={/context/openscad/openscad -o \externalfilteroutputfile},
   output={\externalfilterbasefile.png},
   cache=force,
   readcommand=\ReadImage]
\define[1]\ReadImage{\externalfigure[#1]}

\starttext
\startopenscad
  square(4,2);
\stopopenscad
\stoptext

This works fine. I now want to use the following options added to the
command line: --view axes,edges,scales --viewall

When I create an Openscad file test.scad, I can run it fine with the
following command line at a CLI window:

openscad.com test.scad -o test.png --view axes,edges,scales --viewall

When I add this to the filtercommand as following

[filtercommand={/context/openscad/openscad -o
\externalfilteroutputfile --view axes,edges,scales --viewall}

I cannot get it to run. Is there anything I am missing?

Thanks
