Customizing Essence Language Symbol Stencils

Look at the file OpenGraph.js

inside the javascript, there are constructors for each symbols and you can find the logics for drawing graphics:

`/**

• 드로잉할 Shape 을 생성하여 반환한다.

• @return {OG.geometry.Geometry} Shape 정보

• @override */ OG.shape.essencia.Alpha.prototype.createShape = function () { var geom1, geomCollection = [];

  if (this.geom) { return this.geom; }

  geom1 = new OG.geometry.Rectangle([0, 0], 90, 100);

  geomCollection.push(geom1); geomCollection.push(new OG.geometry.Line([90, 50], [100, 0])); geomCollection.push(new OG.geometry.Line([90, 50], [100, 100]));

  this.geom = new OG.geometry.GeometryCollection(geomCollection);

  this.geom.style = new OG.geometry.Style({ 'r' : 20, 'label-position': 'center', 'stroke-width' : 2.5 });

  return this.geom; }; `
