LoadImage loads an image from a file.
LocationToTileID converts a lat/lon location into a tile ID.
MercatorLocationToPixel converts a lat/lng/zoom location (in degrees) to a pixel location in the global space.
MercatorLocationToTileID builds on MercatorLocationToPixel to fetch the TileID of a given location.
MercatorPixelToLocation converts a given (global) pixel location and zoom level to a lat and lng (in degrees).
NewFileCache creates a new file cache instance.
NewMaps Create a new Maps API wrapper.
NewTile creates a tile with a base RGBA object.
PixelToHeight Converts a pixel to a height value for mapbox terrain tiles Equation from https://www.mapbox.com/blog/terrain-rgb/.
SaveImageJPG writes an image instance to a jpg file.
SaveImagePNG writes an image instance to a png file.
StitchTiles combines a 2d array of image tiles into a single larger image Note that all images must have the same dimensions for this to work.
TileIDToLocation converts a tile ID to a lat/lon location.
WrapTileID wraps tile IDs by level for api requests eg.

# Variables
Center preconfigured centering helper.
# Structs
DrawConfig configures image drawing.
FileCache is a simple file-based caching implementation for map tiles This does not implement any mechanisms for deletion / removal, and as such is not suitable for production use.
Maps api wrapper instance.
Tile is a wrapper around an image that includes positioning data.
# Interfaces
Cache interface defines an abstract tile cache This can be used to limit the number of API calls required to fetch previously fetched tiles.
# Type aliases
Interpolate function to be passed to generic line interpolator.
Justify sets image offsets for drawing.
MapFormat specifies the format in which to return the map tiles.
MapID selects which map to fetch from the API.
