Class
ShumateMapSource
Description [src]
abstract class Shumate.MapSource : GObject.Object {
parent_instance: GObject
}The base class for all map sources. Map sources fill ShumateTile objects
with images from various sources: a web API, for example, or a test pattern
generated on demand.
The most common map source is ShumateRasterRenderer, which fetches tiles
using a ShumateTileDownloader.
