Class: Box

Box

A Box consists of an x and y point (the top-left corner) and a width and height. The Box position can be relative to the canvas where the position stays static or to the map in which case the position moves with the map.

Attributes

Attribute Type Description
width Number Width of box (Default: 100)
height Number Height of box (Default: 100)
padding Number Sets paddedX and paddedY values (Default: 0)
position String|Object Where to place the box. See Position for details.
anchor String|Object Where the position should be anchored to the box.
color String|Color A string describing the color. See Color for details. (DOESN'T DO ANYTHING YET)

Position: If the position is on (i.e. relativeTo) the 'canvas', the box will be in a static position and will not move as the map is panned. String values (e.g. top-right, bottom-middle, etc) position the box appropriately. An object with xPercent and yPercent values between 0 and 100 will position the box along the x and y axes starting from the top-left. The string values are associated with specific offsets. For example,

  • top-left = {xPercent: 0, yPercent: 0}
  • middle-center = {xPercent: 50, yPercent: 50}
  • bottom-right = {xPercent: 100, yPercent: 100}

If position is on (i.e. relativeTo) the 'map', the box will move with the map as it's panned. The position will consist of

  • lengthPercent: 0 - start of map; 50 - middle of map; 100 - end of map
  • mapOffset or bbOffsetPercent: distance from the thbackbone
