   not off the top of my head, could you provide the font + command that you are running?

   I was using your code exactly but a font called norwester. I then went and tried your font and found that its a negative space font. So it was working as expected by creating the gcode from the fill area. I was using the gcanvas example to create the same effect by putting a rectangle behind.

     roundRect(ctx, 0,0,180,60,5);
     ctx.fill('evenodd');
   
   function roundRect(ctx, x, y, w, h, r) {
     if (w < 2 * r) r = w / 2;
     if (h < 2 * r) r = h / 2;
     ctx.moveTo(x+r, y);
     ctx.arcTo(x+w, y,   x+w, y+h, r);
     ctx.arcTo(x+w, y+h, x,   y+h, r);
     ctx.arcTo(x,   y+h, x,   y,   r);
     ctx.arcTo(x,   y,   x+w, y,   r);
     ctx.closePath();
   }
   

   I can't seem to recreate it with your code any ideas.

   very interesting - I tried to repro what you are doing and downloaded https://www.fontsquirrel.com/fonts/norwester - is that the font you are using?

   I ran into an opentype.js error on 0.3.x and 0.8.x:

   Ya i don't get any errors, i'm running newest version of opentype. That is the font i was using also. And it works as expected. I had to put in a feed to preview in the visualization but thats it.

   I can't only get inset code still playing around with it. any ideas
