Properties

left
{Number} Minimum horizontal coordinate.
bottom
{Number} Minimum vertical coordinate.
top
{Number} Maximum vertical coordinate.

Functions

ZOO.Bounds

Construct a new bounds object.

Parameters

left {Number} The left bounds of the box. Note that for width calculations, this is assumed to be less than the right value.
bottom {Number} The bottom bounds of the box. Note that for height calculations, this is assumed to be more than the top value.
right {Number} The right bounds.
top {Number} The top bounds.
clone
clone:function()

Create a cloned instance of this bounds.

Returns

{ZOO.Bounds} A fresh copy of the bounds

equals
equals:function(bounds)

Test a two bounds for equivalence.

Parameters

bounds {ZOO.Bounds}

Returns

{Boolean} The passed-in bounds object has the same left, right, top, bottom components as this. Note that if bounds passed in is null, returns false.

toString
toString:function()

Returns

{String} String representation of bounds object. (ex. <i>”left-bottom=(5,42) right-top=(10,45)”</i>)

toBBOX
toBBOX:function(decimal)

Parameters

decimal {Integer} How many significant digits in the bbox coords? Default is 6

Returns

{String} Simple String representation of bounds object. (ex. <i>”5,42,10,45”</i>)

toGeometry
toGeometry: function()

Create a new polygon geometry based on this bounds.

Returns

{ZOO.Geometry.Polygon} A new polygon with the coordinates of this bounds.

getWidth
getWidth:function()

Returns

{Float} The width of the bounds

getHeight
getHeight:function()

Returns

{Float} The height of the bounds (top minus bottom).

add
add:function(x,y)

Parameters

x {Float}
y {Float}

Returns

{ZOO.Bounds} A new bounds whose coordinates are the same as this, but shifted by the passed-in x and y values.

extend
extend:function(object)

Extend the bounds to include the point, lonlat, or bounds specified. Note, this function assumes that left < right and bottom < top.

Parameters

object {Object} Can be Point, or Bounds.

intersectsBounds
intersectsBounds:function(bounds,inclusive)

Determine whether the target bounds intersects this bounds. Bounds are considered intersecting if any of their edges intersect or if one bounds contains the other.

Parameters

bounds {ZOO.Bounds} The target bounds.
inclusive {Boolean} Treat coincident borders as intersecting. Default is true. If false, bounds that do not overlap but only touch at the border will not be considered as intersecting.

Returns

{Boolean} The passed-in bounds object intersects this bounds.

containsBounds
containsBounds:function(bounds,partial,inclusive)

Determine whether the target bounds is contained within this bounds.

Parameters

bounds {ZOO.Bounds} The target bounds.
partial {Boolean} If any of the target corners is within this bounds consider the bounds contained. Default is false. If true, the entire target bounds must be contained within this bounds.
inclusive {Boolean} Treat shared edges as contained. Default is true.

Returns

{Boolean} The passed-in bounds object is contained within this bounds.
