Path definition

\n * A parameterized path is defined like this:\n *
\n   * 'GATEWAY_PARALLEL': {\n   *   d: 'm {mx},{my} {e.x0},0 0,{e.x1} {e.x1},0 0,{e.y0} -{e.x1},0 0,{e.y1} ' +\n          '-{e.x0},0 0,-{e.y1} -{e.x1},0 0,-{e.y0} {e.x1},0 z',\n   *   height: 17.5,\n   *   width:  17.5,\n   *   heightElements: [2.5, 7.5],\n   *   widthElements: [2.5, 7.5]\n   * }\n   * 
\n *

It's important to specify a correct height and width for the path as the scaling\n * is based on the ratio between the specified height and width in this object and the\n * height and width that is set as scale target (Note x,y coordinates will be scaled with\n * individual ratios).

\n *

The 'heightElements' and 'widthElements' array must contain the values that will be scaled.\n * The scaling is based on the computed ratios.\n * Coordinates on the y axis should be in the heightElement's array, they will be scaled using\n * the computed ratio coefficient.\n * In the parameterized path the scaled values can be accessed through the 'e' object in {} brackets.\n *

    \n *
  • The values for the y axis can be accessed in the path string using {e.y0}, {e.y1}, ....
  • \n *
  • The values for the x axis can be accessed in the path string using {e.x0}, {e.x1}, ....
  • \n *
\n * The numbers x0, x1 respectively y0, y1, ... map to the corresponding array index.\n *

Use case

\n *

Use case is to scale the content of elements (event, gateways) based\n * on the element bounding box's size.\n *

\n *

Why not transform

\n *

Scaling a path with transform() will also scale the stroke and IE does not support\n * the option 'non-scaling-stroke' to prevent this.\n * Also there are use cases where only some parts of a path should be\n * scaled.

\n *\n * @param {String} pathId The ID of the path.\n * @param {Object} param

\n * Example param object scales the path to 60% size of the container (data.width, data.height).\n *

\n   *   {\n   *     xScaleFactor: 0.6,\n   *     yScaleFactor:0.6,\n   *     containerWidth: data.width,\n   *     containerHeight: data.height,\n   *     position: {\n   *       mx: 0.46,\n   *       my: 0.2,\n   *     }\n   *   }\n   *   
\n *
    \n *
  • targetpathwidth = xScaleFactor * containerWidth
  • \n *
  • targetpathheight = yScaleFactor * containerHeight
  • \n *
  • Position is used to set the starting coordinate of the path. M is computed:\n *
      \n *
    • position.x * containerWidth
    • \n *
    • position.y * containerHeight
    • \n *
    \n * Center of the container
     position: {\n   *       mx: 0.5,\n   *       my: 0.5,\n   *     }
    \n * Upper left corner of the container\n *
     position: {\n   *       mx: 0.0,\n   *       my: 0.0,\n   *     }
