Providers

When we use OpenLayersMap we must provide to our root module an OL_CONFIG config in our app.module.ts we pass

import {OL_CONFIG} from '@ansyn/ol';

...
providers: [
  {
    provide: OL_CONFIG,
    useValue: {}
 }
...
]

We can pass an empty object to use the default config or pass an object with the structure:

{
    tilesLoadingDoubleBuffer: {
        debounceTimeInMs: number;
        timeoutInMs: number;
    };
    floatingPositionSuffix?: string;
}

• tilesLoadingDoubleBuffer: time to wait when loading tiles before show them
  • debounceTimeInMs: add delay to the event.
  • timeoutInMs: start showing the tiles.
• floatingPositionSuffix: string to concat to the coordinates position.
