Protected Properties

Property Type Description
$precision integer Overwrite this property in extended class to adjust precision of numbers. !!!CAUTION!!! 1) Adjusting this value will not guarantee that third party libraries will understand the change. 2) Float point arithmetic IS NOT real number arithmetic. PHP's internal float precision may contribute to undesired rounding.

Public Methods

Method Description
decode ( string $string ) : array Reverse Google Polyline algorithm on encoded string.
encode ( array $points ) : string Apply Google Polyline algorithm to list of points.
flatten ( array $array ) : array Reduce multi-dimensional to single list
pair ( array $list ) : array Concat list into pairs of points
