Methods

getMaxZoomTileCoord(z, x, y)

Returns the TileCoord of the oblique maximum zoom level if z coordinate is above the maximum zoom level, or the same as input if not. The maximum zoom level in an oblique is the one that shows the image at best possible resolution. There can be extra zoom levels, but those are a resampling of resolution at maximum zoom level.

Parameters:
