Path definition

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

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

+ *

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

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

Use case

+ *

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

+ *

Why not transform

+ *

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

+ * + * @param {string} pathId The ID of the path. + * @param {Object} param

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