Methods

experimental staticol.proj.addProjection(projection)

src/ol/proj/proj.js, line 376

Name	Type	Description
projection	ol.proj.Projection	Projection.

experimental staticol.proj.configureProj4jsProjection(options){ol.proj.Projection}

src/ol/proj/proj.js, line 721

Name	Type	Description
options	Proj4js projection options. Name Type Description code string The SRS identifier code, e.g. EPSG:31256. extent ol.Extent | undefined The validity extent for the SRS. global boolean | undefined Whether the projection is valid for the whole globe. Default is false.

Returns:

experimental staticol.proj.get(projectionLike){ol.proj.Projection}

src/ol/proj/proj.js, line 474

Name	Type	Description
projectionLike	ol.proj.ProjectionLike	Either a code string which is a combination of authority and identifier such as "EPSG:4326", or an existing projection object, or undefined.

experimental staticol.proj.getTransform(source, destination){ol.TransformFunction}

src/ol/proj/proj.js, line 556

Given the projection-like objects this method searches for a transformation function to convert a coordinates array from the source projection to the destination projection.

Name	Type	Description
source	ol.proj.ProjectionLike	Source.
destination	ol.proj.ProjectionLike	Destination.

experimental staticol.proj.getTransformFromProjections(sourceProjection, destinationProjection){ol.TransformFunction}

src/ol/proj/proj.js, line 573

Searches a function that can be used to convert coordinates from the source projection to the destination projection.

Name	Type	Description
sourceProjection	ol.proj.Projection	Source projection.
destinationProjection	ol.proj.Projection	Destination projection.

experimental staticol.proj.transform(point, source, destination){ol.Coordinate}

src/ol/proj/proj.js, line 693

Name	Type	Description
point	ol.Coordinate	Point.
source	ol.proj.ProjectionLike	Source.
destination	ol.proj.ProjectionLike	Destination.

experimental staticol.proj.transformWithProjections(point, sourceProjection, destinationProjection){ol.Coordinate}
