Method Details
latLngToPoint (lat, lng, opt_out) : {H.math.Point}
This method transforms geographical lat/lng coordinates to a projected point in the range [0...1].
- Parameters:
-
lat: -
{number} - latitude A value indicating the latitude
-
lng: -
{number} - longitude A value indicating the longitude
-
opt_out: -
{H.math.Point=} [optional] - An optional point to receive the result
- Returns:
-
{H.math.Point} - An object containing the result of the conversion
xyToGeo (x, y, opt_out, opt_noWrap) : {H.geo.Point}
This method transforms projected x/y coordinates in the range [0...1] to a geographical point.
- Parameters:
-
x: -
{number} - A value indicating the x coordinate
-
y: -
{number} - A value indicating the y coordinate
-
opt_out: -
{H.geo.Point=} [optional] - An optional point object to receive the result
-
opt_noWrap: -
{boolean=} [optional] - Indicates whether to treat the world as wrapped along the longitude axis. When set to false, x-coordinates are normalized to the range [0..1]. When set to true, x-coordinates are clamped to the range [0..1]. Default is false.
- Returns:
-
{H.geo.Point} - An object containing the results of the conversion
pointToGeo (point, opt_out, opt_noWrap) : {H.geo.Point}
This method transforms a projected point in the range [0...1] to a geographical point.
- Parameters:
-
point: -
{H.math.IPoint} - An object representing the point to convert
-
opt_out: -
{H.geo.Point=} [optional] - An optional geographical point object to receive the results
-
opt_noWrap: -
{boolean=} [optional] - Indicates whether to treat the world as wrapped along the longitude axis. When set to false, x-coordinates are normalized to the range [0..1]. When set to true, x-coordinates are clamped to the range [0..1]. Default is false.
- Returns:
-
{H.geo.Point} - A geographical point object containing the results of the conversion
geoToPoint (geoPoint, opt_out) : {H.math.Point}
This method transforms a geographical point to a projected point in the range [0...1].
- Parameters:
-
geoPoint: -
{H.geo.IPoint} - An object containing geographical coordinates
-
opt_out: -
{H.math.Point=} [optional] - An optional point to receive the result
- Returns:
-
{H.math.Point} - An object containing the results of the conversion
