Namespace MapLibreNative.Maui

Classes

MlnCache: Provides the default path of MapLibre's cache database. The map views and MlnOfflineManager both default to this path, so offline regions downloaded by the manager are served to the map automatically.

Wraps mln_frontend_t*.

Ownership note: once passed to MlnMap, the map takes ownership of the underlying native pointer and will destroy it via mln_map_destroy. Dispose() becomes a no-op after MapLibreNative.Maui.MlnFrontend.TransferOwnership() is called. Do not call Dispose() after Dispose().

MlnLayer: Non-owning handle to a layer inside a loaded style.

MlnMap: Wraps mln_map_t*. Dispose on the render thread.

MlnNetwork: Controls MapLibre's process-global network state. When offline, all network requests are suspended and only cached / offline resources are served; switching back online resumes queued requests.

MlnOfflineManager: Manages offline region downloads and the ambient cache. Wraps mln_offline_manager_t. Dispose when done; in-flight operations complete safely after disposal.

MlnOfflineRegion: An offline region stored in the cache database.

MlnOfflineRegionStatus: Download status of an offline region.

MlnRunLoop: Wraps mln_runloop_t*. Must be created and disposed on the map thread.

MlnSource: Non-owning handle to a source inside a loaded style.

MlnStyle: Provides access to sources and layers. This is a non-owning handle — do not dispose it; it is invalidated when the parent MlnMap is disposed.

NativeMethods: Raw P/Invoke bindings — prefer the typed wrappers in MlnMap etc.

TerrainIcon: Vector geometry for the on-map 3D-terrain control's icon, ported from maplibre-gl-js's src/css/svg/maplibregl-ctrl-terrain.svg so the control reads the same as the web map's.

Structs

BoundOptions: Camera bounds returned by GetBounds().

CameraResult: Camera result from a fit-to-points operation.

MlnOfflineError: Error payload for RegionError.

MlnOfflineProgress: Progress payload for RegionProgress.

Enums

GpsFollowZoomMode: How the GPS control chooses the camera zoom when Follow mode engages (via the on-map GPS button, or the first fix that arrives while following). Later fixes never change the zoom, so a manual pinch/scroll zoom sticks until Follow is re-entered.

MapControlCorner: The corner of the map that an on-map overlay control (navigation, GPS or attribution) is anchored to.

MlnDebugOptions: Bitmask of debug visualisation overlays. OR together the flags you want.

MlnLogLevel: Log severity levels emitted by MapLibre Native.

MlnRenderBackend: The renderer the loaded native library was built against.

MlnStatus: Return status from every mutating C ABI function. Non-zero means failure; call GetLastError() for a diagnostic message.

TerrainLoadMode: How much work 3D terrain is allowed to do per frame while it loads.

Delegates

NativeMethods.LogFn: Log intercept callback. Return non-zero to consume the record (suppress default output).

NativeMethods.MapObserverFn

NativeMethods.OfflineDoneFn: One-shot completion callback for offline operations with no payload.

NativeMethods.OfflineProgressFn: Recurring download-progress callback for an observed region.

NativeMethods.OfflineRegionErrorFn: Recurring download-error callback for an observed region. reason matches mbgl's Response::Error::Reason values (2=NotFound 3=Server 4=Connection 5=RateLimit 6=Other), or 100 when the Mapbox tile count limit was exceeded.

NativeMethods.OfflineRegionsFn: One-shot callback delivering a JSON array of offline regions.

NativeMethods.OfflineStatusFn: One-shot callback delivering a region status JSON object.
