GeoTiffImageLayer

open class GeoTiffImageLayer : TiledImageLayer

Displays a tiled GeoTIFF — an orthophoto, a scanned chart, a colour-mapped raster — as an ordinary image layer. Tiles are resampled straight out of the file's own tile grid at the overview level closest to each tile's resolution, so the layer costs the same per frame whether the source is 50 MB or 50 GB.

The layer holds the dataset open for as long as it is displayed; close releases the underlying file. A clone shares the dataset with its original, so close only once.

Properties

cachedSourceInfo

val TiledImageLayer.cachedSourceInfo: CachedSourceInfo?

Cache identity of this layer's tile source, or null when the layer isn't wired through a cache (network-only). Walks the layer's tile factory chain, looking for a CachedSourceInfoProvider — typically a CachedTileSource that wraps an IDB / gpkg / filesystem TileStore.

count

val count: Int

dataset

val dataset: GeoTiffDataset

The open GeoTIFF backing this layer.

displayName

open override var displayName: String?

isDynamic

open override var isDynamic: Boolean

isEnabled

open override var isEnabled: Boolean

isPickEnabled

open override var isPickEnabled: Boolean

maxActiveAltitude

open override var maxActiveAltitude: Double

minActiveAltitude

open override var minActiveAltitude: Double

opacity

open override var opacity: Float

sector

val sector: Sector

Geographic bounds of the imagery.

tiledSurfaceImage

var tiledSurfaceImage: TiledSurfaceImage?

type

val type: String?

Functions

addAllRenderables

fun addAllRenderables(layer: RenderableLayer)

fun addAllRenderables(iterable: Iterable<Renderable>)

addRenderable

fun addRenderable(renderable: Renderable)

fun addRenderable(index: Int, renderable: Renderable)

clearRenderables

fun clearRenderables()

clone

open override fun clone(): GeoTiffImageLayer

fun close()

Release the underlying file. The layer renders nothing afterwards.

contentEntry

fun TiledImageLayer.contentEntry(contentManager: ContentManager? = null): ContentEntry?

One-stop accessor for "this image layer's content view." Lookup order:

getRenderable

fun getRenderable(index: Int): Renderable

getRenderablesByDisplayName

fun getRenderablesByDisplayName(name: String): List<Renderable>

getUserProperty

open override fun getUserProperty(key: Any): Any?

hasUserProperty

open override fun hasUserProperty(key: Any): Boolean

indexOfRenderable

fun indexOfRenderable(renderable: Renderable): Int

indexOfRenderableNamed

fun indexOfRenderableNamed(name: String): Int

indexOfRenderableWithProperty

fun indexOfRenderableWithProperty(key: Any, value: Any): Int

isEmpty

fun isEmpty(): Boolean

isWithinActiveAltitudes

open override fun isWithinActiveAltitudes(rc: RenderContext): Boolean

iterator

open operator override fun iterator(): MutableIterator<Renderable>

launchBulkRetrieval

fun TiledImageLayer.launchBulkRetrieval(sector: Sector, resolution: ClosedRange<Angle>, scope: CoroutineScope = GlobalScope, maxRetries: Int = 3, retryTimeoutShort: Duration = 5.seconds, retryTimeoutLong: Duration = 15.seconds, overrideCache: Boolean = false, onProgress: (downloaded: Long, skipped: Long, total: Long) -> Unit? = null): Job?

Download every tile within sector across the resolution range into the layer's underlying TileStore (when the layer was constructed with a CachedTileSource). Returns the launched Job for cancellation; returns null when the layer's tile factory isn't backed by a TileSourceFactoryAdapter (i.e. no source-based wiring, so bulk-via-source is impossible).

putUserProperty

open override fun putUserProperty(key: Any, value: Any): Any?

removeAllRenderables

fun removeAllRenderables(renderables: Iterable<Renderable>): Boolean

removeRenderable

fun removeRenderable(renderable: Renderable): Boolean

fun removeRenderable(index: Int): Renderable

removeUserProperty

open override fun removeUserProperty(key: Any): Any?

render

open override fun render(rc: RenderContext)

setOfflineOnly

fun TiledImageLayer.setOfflineOnly(offlineOnly: Boolean = true)

Toggle the cache-only flag on a cache-attached layer or coverage.

setRenderable

fun setRenderable(index: Int, renderable: Renderable): Renderable
