CrsSimple class

A simple CRS that maps longitude and latitude into x and y directly. May be used for maps of flat surfaces (e.g. game maps).

Note that the y axis should still be inverted (going from bottom to top). distance() returns simple euclidean distance.

Properties

code → String
Crs code
no setteroverride
hashCode → int
The hash code for this object.
no setterinherited
infinite → bool
If true, the coordinate space will be unbounded (infinite in both axes).
no setteroverride
latBounds → Tuple2<double, double>?
Returns a Tuple2<double 1, double 2) where longitude has been wrapped according to the CRS's wrapLng properties, if they are outside the CRS's bounds.
no setteroverride
lngBounds → Tuple2<double, double>?
Returns a Tuple2<double 1, double 2) where latitude has been wrapped according to the CRS's wrapLat properties, if they are outside the CRS's bounds.

Methods

distance(LatLng position, LatLng destination) → double
Returns the distance between two geographical coordinates.
override
getProjectedBounds(double? zoom) → Bounds?
Returns the projection's bounds scaled and transformed for the provided zoom.
inherited
latlngToPoint(LatLng? position, double? zoom) → UPoint
Projects latlng coordinates into pixel coordinates for a given zoom.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
pointToLatLng(UPoint point, double? zoom) → LatLng?
The inverse of latlngToPoint. Projects pixel coordinates on a given zoom into latlng coordinates.
inherited
project(LatLng? latlng) → UPoint?
Projects geographical coordinates into coordinates in units accepted for this CRS (e.g. meters for EPSG:3857, for passing it to WMS services).
inherited
scale(double? zoom) → double
Returns the scale used when transforming projected coordinates into pixel coordinates for a particular zoom.
override
toString() → String
A string representation of this object.
inherited
unproject(UPoint point) → LatLng?
Given a projected coordinate returns the corresponding LatLng. The inverse of project.
inherited
wrapLatLng(LatLng latlng) → LatLng
Returns a LatLng where lat and lng has been wrapped according to the CRS's wrapLat and wrapLng properties, if they are outside the CRS's bounds.
inherited
wrapLatLngBounds(LatLngBounds bounds) → LatLngBounds
Returns a LatLngBounds with the same size as the given one, ensuring that its center is within the CRS's bounds.
inherited
zoom(double scale) → double
Inverse of scale(), returns the zoom level corresponding to a scale factor of scale.
override

Operators

operator ==(Object other) → bool
The equality operator.
