getboundingbox v1.0.0

getboundingbox

This is a utility function to calculate the bounding box of series of 2D points

var getBounds = require('getboundingbox')

var path = [ [-100, 12], [-52, 25], [6, 13] ]
var box = getBounds(path)

The result will be:

{ 
    maxX: 6,
    maxY: 25, 
    minX: -100, 
    minY: 12 
}

Usage

bounds(path[, out])

Computes the min and max x, y points for the given path. If path is an empty array, the bounds will be empty (all zero).

You can specify out to re-use an object rather than creating a new one.

This is safe to with Array.map/filter/etc, e.g.

if (paths.map(bounds).some(intersect)) {
    ...
}
