[OpenLayers-Users] OL 4.2 with TypeScript:How to extend index.d.ts?

[Olivier Guyot]

You could try using *tileGrid.getTileRangeForExtentAndResolution(extent,
resolution)* instead, although this is not part of the public API either.

Whichever way you chose, it doesn't make sense that your code gives you an
execution error on *tileGrid.getFullTileRange* but not on
*tileGrid.getTileCoordForCoordAndResolut**ion*, as a ol.tilegrid.TileGrid
should have both functions on its prototype. Are you sure this is the error
you're getting?
