Constructor detail
Projection()constructor
public function Projection(param:Object = null)

Abstract projection class constructor.

Creates new IProjection object with the default parameters. Properties defined in param object will override the default values.

Here is a list of properties you can specify in the param object:

Parameters
PropertyTypeDefaultDescription
tileSize uint 256 Specifies tile size in pixels.
repeatmap Boolean true Defines whether to repeat map horizontally.
transform ProjectionTransform null Specifies transformation object to use.
size Size Size(256,256) Specifies map image size. The scale of image is defined in the scale parameter. If you specify this parameter in the param object, map bounds will be recalculated.
bounds LatLngBounds LatLngBounds(LatLng(-90,-180), LatLng(90,180)) Specifies map bounds in geogrpahical coordinates.
param:Object (default = null) — Object that specifies properties of the Projection you need to override upon it's creation
