function proj4js_load_definition in Proj4JS 7

Load a definition. The definition is made available in the client when behaviors load. Note due to Drupal loading behaviours in random order you need to call Drupal.behaviors.proj4js.attach yourself when your behaviours depend on the presence of the projection definitions. See the discussion in #1940410 for details.

Parameters

String $identifier: For example "EPSG:2056".

String $definition: Proj4 definition.

File

Code

function proj4js_load_definition($identifier, $definition) {
  static $included_definitions = array();
  if (!in_array($identifier, $included_definitions)) {
    libraries_load('proj4js');
    drupal_add_js(proj4js_load_definition_js_settings($identifier, $definition), 'setting');

    // Track previously loaded projections because they contain the same
    // settings anyway and emitting them twice does not yield a benefit.
    $included_definitions[] = $identifier;
  }
