transform property

GeoTransform? transform

A transform applied to any input geometry before it is rendered.

The null transform represents the identity transformation: the input geometry is not transformed and is instead rendered directly in raw coordinates. This can be useful for fast rendering of pre-projected geometry, or for fast rendering of the equirectangular projection.

Is typically one of built-in geographic projections; however, any object that implements GeoTransform can be used, enabling the use of custom projections.

Implementation

GeoTransform? get transform => _transform;

void transform=(GeoTransform? _)

Implementation

set transform(GeoTransform? _) {
  if (_ == null) {
    _transform = null;
    _transformStream = identity;
  } else {
    _transformStream = (_transform = _);
  }
}
