Tiler

object Tiler extends AnyRef

Used to create tiled rasters, as well as tilesets on the filesystem, based on a source raster.

These files (on disk) can be used by a TileSetRasterData, or loaded into an array of rasters to be used by TileArrayRasterData.

A tile set has a base path (e.g. "foo/bar") which is used along with the "tile coordinates" (e.g. tile 0,4) to compute the path of each tile (in this case "foo/bar_0_4.arg").

    Write a TiledRasterData to disk as a tile set, using the provided path and name to determine what filenames to use.

  31. def writeTilesFromFunction(pixelCols: Int, pixelRows: Int, re: RasterExtent, name: String, path: String, f: (Int, Int, TileLayout, RasterExtent) ⇒ Raster): Unit

    Write a TiledRasterData to disk as a tile set, creating each tile's data by executing a function that returns a raster.

    Write a TiledRasterData to disk as a tile set, creating each tile's data by executing a function that returns a raster.

    Note that the function will need to generate its RasterExtent from the ResolutionLayout, e.g. val rl = tileLayout.getResolutionLayout(re) val tileRasterExtent = rl.getRasterExtent(col, row)
