Zoom limitation

By default, the minimum and maximum zoom levels are set to 0.25 and 3.0, respectively. These limitations are convenient not to show the objects too small or too large.

Set the minimum and maximum zoom levels.

  zoom: {
    max: 2.0,
    min: 0.5
  },

Background style

By default, the field has a border and radial gradient background.

  style: "border: solid 1px silver; background: radial-gradient(white, silver);"
