translate property

@override List<double> translate

The projection's translation offset.

The translation offset is specified as an two-element array [tx, ty], which determines the pixel coordinates of the projection’s center. The default translation offset places ⟨0°,0°⟩ at the center of a 960×500 area.

Implementation

@override
get translate => _lower48.translate;

@override void translate=(List<double> _)

Implementation

@override
