If a source (based on `ol/source/TileImage` or `ol/source/Image`) has a projection different from the current `ol/View`’s projection then the reprojection happens automatically under the hood.

### Custom projection
The easiest way to use a custom projection is to add the [Proj4js](http://proj4js.org/) library to your project and then define the projection using a proj4 definition string. It can be installed with

A possible general solution would be to calculate the forward transformation for every vertex as well - but this would significantly decrease performance (especially for computationally expensive transformations).
Therefore a recommended workaround is to define a proper visibility extent on the `ol.layer.Tile` in the view projection.
Setting such a limit is demonstrated in the [reprojection demo example](https://openlayers.org/en/main/examples/reprojection.html).

### Resolution calculation
When determining source tiles to load, the ideal source resolution needs to be calculated.
