// Transparent Proj4js support:

// Now when we create an ol.proj.Projection instance with the 'EPSG:21781' code,

|
// OpenLayers will pick up parameters like units and transform functions from
|
|
// Proj4js.
|

|
|
// determine the view resolution for zoom level 0. Recommended values for a

// projection's validity extent can be found at http://epsg.io/.
