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.
